Frequently Asked Questions

The Biosense® device measures breath acetone, which is produced as a byproduct of ketogenesis. The concentration of acetone in the breath indicates your level of nutritional ketosis. The device represents breath acetone in scaled units called ACEs, from 0-40. The higher your ACEs, the more fat is being burned for fuel in your body. On the device you can easily see which ACE level corresponds to light, advanced or deep ketosis.

Biosense® contains a highly sensitive chemical sensor. To protect your device from potential contamination from solvents, such as hand sanitizer, nail polish and other harmful chemicals, store BIOSENSE® in the protective Mylar bag provided with the device. The Mylar bag is impermeable to most solvents and will provide better protection than other permeable bags and containers.

The Biosense® device uses patent-pending Deep Lung Sampling technology to perform breath acetone measurements. The consistent sampling of only the latter part of the exhalation enables the most accurate level of breath acetone detection for nutritional ketosis monitoring.

The Biosense® system is intended for self-testing of acetone (ketone bodies) in the breath. It is intended for home (lay user) or professional use in the management of patients seeking to reach or maintain nutritional ketosis. The system should not be used to diagnose or treat any disease or condition. Follow your healthcare professional’s advice before making any changes to your disease management program.

Biosense® is an FDA registered Class 1 medical device.

Battery life depends upon the preparation time, the number of measurements you make each day and the standby time (how long your device is asleep between each measurement.) From fully charged, and testing between 1-5 measurements each day, your battery should last 2-4 days between charges.Note that your Biosense device runs additional sensor diagnostics when asleep and plugged in to the charger. Plugging your device in each night, or every few nights, will therefore help reduce preparation time for measurements and maintain accuracy.

Plug the device into a power source using the provided micro-USB charging cable.

To preserve the performance of the device it is best to clean it once a week. Remove the mouthpiece from the device before cleaning by gently squeezing its base and pulling it away from the device. Use a cloth and water to clean your mouthpiece. Do not use cleaning wipes that contain alcohol as this can negatively impact device performance.

If your device determines that extra sensor warmup or clearing is necessary, it will automatically activate the Smart Clean process. Periodic Smart Clean activations are a normal part of regular device use and do not indicate device malfunction.

Please, remember solvents like hand sanitizer, nail polish remover, and other aromatics may react with the sensor and force the device into this cycle.

Biosense® contains a highly sensitive chemical sensor. Solvents like hand sanitizer, nail polish remover, and other aromatics may react with the sensor and interfere with sensor preparation and clearing. If the sensor is affected by environmental solvent exposure or is otherwise unable to adequately prepare, a red indicator will appear on the screen and direct you to run a sensor Clean. On your device select Settings, scroll down to Clean, and select. This process takes approximately 10 minutes to complete and requires your device to be plugged into the charger.

Testing after consuming certain foods or drinks can result in false high measurements. For best results, wait 60 minutes after:

• Eating
• Smoking/vaping
• Drinking sodas or flavored waters
• Consuming items with flavorings such as:
  • Toothpaste
  • Mouthwash
  • Cough drips
  • Breath mints/Chewing gum
  • Lip balm
  • Artificial sweeteners

Do not test after consuming alcohol. For best results, wait until the next morning.

The color scale on the Biosense device gives you a quick and easy indication of your state of ketosis.

Once you connect to the Biosense® mobile app, your device’s clock will be automatically updated with the current time on your mobile device. The Biosense® will retain this clock setting until it is fully powered off or until it completely loses its battery. If you prefer to use the device without the mobile app, you will need to manually set the device clock. You can do this by pressing the MENU button on the device and selecting Set Time.

Yes! You can view your past 10 measurements by pressing the MENU button on the device and selecting History.

Up to 50 measurements can be stored on the device.

The device vibration is caused by an activated pump, which pulls your breath sample from the mouthpiece into the device interior. The pumping mechanism is a key component of the patent-pending Deep Lung Sampling technology, which enables highly accurate breath acetone sensing. The pump also activates during the sensor preparation phase. Two short vibrations also indicate that an action is required by the user.

In order to ensure the most accurate breath acetone sensing available, the Biosense® device must prepare its highly selective sensor to receive a breath sample. Failure to adequately prepare the sensor leads to performance that does not meet our accuracy standards.

Biosense® cannot be used while charging due to the safety risk associated with placing a charging device into your mouth.

The device Menu can be accessed from the PRESS START screen. Simply press the SETTINGS (gear) button to access. Scroll with the settings (gear) button and select with the checkmark button.

To provide the most accurate breath measurement possible, your Biosense® device uses a pump to clean the ketone sensor both before and after the measurement, and also to pull a breath sample into the device. The buzzing sound you hear is simply the pump doing its job! You can hear the pump running during the three stages of the measurement:

1) During the “PREPARING DEVICE” phase, the pump will run periodically to make sure the sensor is clean and ready for a measurement.

2) When you reach the “BLOW” screen, blowing into Biosense® will activate the pump again in order to pull a breath sample into the sensor for analysis.  Make sure to keep blowing until the buzzing stops (the pump will buzz twice when sampling is complete) to get the best measurement.

3) Once your results are shown, Biosense® will run the pump a final time in order to clean the breath sample out of the sensor. Cleaning the sensor at the end of the measurement maintains the accuracy of your sensor and helps to speed up the warm-up for your future measurements.

The Biosense® app offers ketone trends, personalized insights and individual goal setting. You can see how long and deep you are in ketosis on any given day, comparing days, weeks and months of your ketosis journey. The daily ketone trends let you easily see the impact of different foods and exercise routines on your ketone levels. The app allows users to add notes and track your meals, fasts, and exercise with your ketone measurements.

First, pair your device to the Biosense® app by tapping the device sync icon located on the navigation bar in the app.

In order to sync data, your device must be paired and the app must be open. If the Biosense® app is in the background or your phone is asleep, the app will not be able to receive data from the device.

Once you have paired your device and opened the app, the Biosense® device will send all previously unsent data during device wakeup AND/OR after a measurement is taken.

Download and open the “Biosense by Readout” app from the app store or google play store. Open the app and navigate to the Home screen. Turn on your Biosense by pressing the check button for three seconds. The device should display “PAIR TO APP TO SET TIME.” On the app, select the pairing icon in the bottom right corner. The popup message will show all devices in range. Your device will broadcast as “B” or “BIOSENSE” + your device’s serial number. Select your device from the list. The popup message will display “Your device is connected.” A blue dot on the Biosense screen indicates that the Biosense is paired to the app. For more details, visit mybiosense.com/pairing.

2. Tap on the icon of preference to access next screen and select done to save.

You can activate the Apple Health Kit and Google Fit integrations in the Biosense onboarding process or in settings by tapping on “Connected Apps” and activating the toggle switch.  The integration will automatically add in your profile information which includes birthday, weight, height and gender.  Exercise data is not included with this integration, but will be available in the future.

To edit your Actions, tap on the “Me” icon in the navigation bar at the bottom of your home screen. Next, tap on “Edit” to the right of “My Actions” near the bottom of the screen. Then tap on the minus sign next to the action you would like to edit. Finally, tap on “Edit” to modify your action and tap “Save” to save your changes.

You will measure 0 ACEs if you are primarily using carbs to fuel your body. This is normal and based on a standard diet which is typically high in carbohydrates and sugars. Even with exercise and fasting, it can be difficult to burn through all the carbs and stored glucose.  

Expert Tip: Reduce your carbohydrate intake from your usual amount and increase your physical activity. It can take 1 to 5 days to see an impact on your ACEs. 

Most people can safely increase their ACEs in three ways:  

1. 1) by eating less carbohydrates and sugars,  
2. 2) by fasting, and  
3. 3) by increasing activity.  

Depending on how many carbohydrates and sugars you are consuming at baseline, it may be difficult to raise your ACEs only through fasting and exercise.  

Expert Tip: Experiment. Log your foods and drinks for a few days and find out how many carbs you are eating in a day. That is your baseline. Next, you can cut back on your carbohydrates. It may take 1-5 days to see the results of your efforts and the ACEs rise. Then, to get to higher ACEs values, incorporate fasting and more physical activity. 

Biology 101, Simplified: 

Getting into a fat burn state or increase the fat burning going on can generally be achieved in three ways: 1) by limiting carb intake, 2) by fasting, and 3) by increasing exercise intensity or duration or both. Some people choose to incorporate all three practices to more quickly achieve fat burn, but it’s not required. 

Why limit carb intake? What you eat has a profound impact on your ability to increase ketones. The carbs you eat, get broken down into sugars, like glucose, fructose and galactose in the blood stream. So, a diet high in carbs can feed your body a steady dose of glucose. 

Your body prioritizes burning glucose for fuel. If there is enough glucose, your body will burn that BEFORE it turns to the backup fuel. Glucose comes from the carbs and sugars you eat and from the glycogen stores (glucose storage).  

If you limit the carbs and sugars you eat, your body begins to run low on the fuel, glucose.  When your body needs a backup fuel supply, it will burn your fat cells to produce ketones to use as backup fuel. The more ketones your body uses for fuel, the more fat you’re burning and the higher your ACEs will be. 

CAUTION: If you take medications for heart failure or diabetes or blood sugar, please consult your healthcare provider before restricting carbohydrates. Your medications may need to be adjusted or discontinued.   

Expert Tip: When you limit the carbs and sugars in your diet enough, you will see your ACEs begin to increase in 1-5 days.  

How many carbs should you have? That depends. Your metabolism is unique to you and processes carbohydrates in its own way.  

Expert Tip: That’s why taking at least 3 Biosense ACEs measurements throughout the day is recommended. This will allow you to observe exactly how your personal carb intake affects your ketone levels over the course of one day.  

Expert Tip: If you are blowing all zero’s for more than 5 days, you are likely consuming more carbs and sugars than your body can tolerate. That may mean you are storing more fat than you are burning. Cut back on your carbs further or try another method to elevate your ACEs. 

What about fasting? Practicing a fasting regimen alongside a low carb diet may hasten ketone production and increase your ACEs number even more.  

CAUTION: IF you have a history of an eating disorder, fasting is NOT recommended. IF fasting causes you to lose control when you do eat, then fasting is also NOT recommended. IF you are pregnant or nursing, fasting is NOT recommended. IF you have an uncontrolled medical condition, please consult your health care professional before you consider any fasting protocols.  

Expert Tip: Fasting is about the number of hours you decide NOT to eat or drink anything- other than water, black coffee or unsweet tea. There are multiple ways to fast (various intermittent fasting, prolonged fasting, alternate day fasting, 5:2 fasting, spiritual fasting, etc.).  You might consider exploring different methods to see which one works best for you. You may also choose to do some kind of fasting on some days, but not every day. Find what fits your schedule.  

What about exercise? Increasing the intensity or total duration of your exercise may also boost your ketone production, as it depletes muscles of glycogen. Glycogen is excess glucose that is stored in muscle and liver tissue, and is quickly used up during physical activity or a workout to supply the body with energy.  

Expert Tip: Keep in mind that it is common to see a dip in ACEs following a workout. This is because during exercise, muscle glycogen particles break down and release glucose back into the bloodstream, causing ACEs to decrease. This effect, however, is usually temporary. 

It is normal for ACEs to go up and down throughout the day and over time. ACEs are influenced by what you eat and do, but are also affected by stress, hormones, and sleep.  

Expert Tip: It is more useful to examine trends in ACEs rather than to focus on individual measurements. 

Biology 101, Simplified: 

Some people find that their ACEs fluctuate quite a bit even within a 5 minute time frame. There are several factors that may contribute to this. 

1. Too many carbs. If you’ve noticed a rapid downward trend in your ACEs numbers, it is possible that your body has started to burn glucose for energy instead of fat. Your body burns glucose first. If you’re providing your body with any amount of glucose – even tiny amounts – in the form of carbs on your plate or in your glass, that may be enough to turn off fat burning and go right back into glucose-burning mode. Your ACEs will plunge.

Expert Tip: Abstaining from the more obvious carb-laden foods and drinks like cookies, cakes, breads, pasta, potatoes, sweetened soda, and fruit juice is a critical first step in exhausting your body’s supply of glucose so that it can burn fat.  

But equally important is making sure you’re not consuming carbs that often sneakily hide in less-obvious places like sauces, dressings, and even some vegetables. 

Expert Tip: Sugar alcohols may also adversely impact your ACEs. Many commercially-available keto-friendly food products contain sugar alcohols like erythritol and xylitol for sweetening. Some artificial sweeteners like sucralose are in “low carb” foods. While these are low in carbs, some people find that consuming them even in small amounts leads to a drop in their ACEs. 

Expert Tip: Check your ACE value before eating. Paying closer attention to carb counts and ingredients before you eat and drink may help you figure out which foods work or don’t work for getting your ACEs back on track. One hour after eating, check your ACE value and see what happened to the number.  

2. Residual glycogen stores. If you’ve been following a low carb diet but are still noticing declining ACEs numbers, it is also possible that your body has still not yet burned through your entire supply of glycogen. Glycogen is the excess glucose that is stored in your muscle and liver tissues. 

Expert Tip: Lower ACEs numbers may indicate that your body is still storing glycogen or you just may need more time to burn it off.  Use your Biosense device to monitor. Increasing exercise intensity may speed up glycogen depletion as your muscles use the stored glycogen for energy. 

3. Operational use of Biosense. ACEs measurements may be inaccurate and fluctuate any time the contact between the Biosense sensor and your breath is compromised. This can be caused by:

• Food stuck in the mouth piece 
• Recent consumption of food or drink* 
• Recent smoking or vaping* 
• Recent use of gum or breath mints* 
• Recent use of toothpaste and/or mouthwash* 
• Exposure to environmental aromatics and solvents like cleaners, perfumes, hand sanitizers, or nail polish remover.  

*Wait at least 1 hour after any of these before you blow into your device.  

You’ll begin using fat for energy when your body has used up most of its stored glucose. Different people have different amounts of stored glucose depending on their recent dietary choices and levels of exercise. For most people, it will take between 1 to 5 days for diet and exercise changes to have an impact on ACEs. 

How quickly your ACEs number increases will largely depend on your lifestyle and metabolic state prior to starting your fat burn journey. If you are used to eating a diet heavy in carbs (starches and sugary foods) and are not following a regular exercise regimen, it will likely take longer for your body to deplete its glycogen stores (glucose stored in your liver and muscles) and it may require more days to see improvements in ACEs.  

Research shows that acetone levels change throughout the day. To get a complete picture of your fat burning patterns, it is best to measure at least 3 times a day; first thing in the morning, before lunch, and before going to bed. 

Biology 101, Simplified: 

Since ketone levels may fluctuate up to 50% during the course of a single day, it is recommended that you measure your ACEs at least 3 times daily to ensure the most accurate assessment of your time in ketosis. 

When should you be taking your ACEs measurements? That depends on your goals. 

Expert Tip: If you’re on the path toward weight loss, aim to measure at least 3 times a day before meals. 

Expert Tip: If your goal is to track how exercise impacts your ketone production, take measurements before and after your workouts to gain that insight. 

Expert Tip: If you’d like to know exactly how a fast affects your ability to burn fat, be sure to measure both at the start and the end of the fast to monitor your progress and determine the best fast duration and pre-fast meals that yield the best results. 

Whatever your reasons to measure ketones, be aware that it can take several hours for your ACEs number to reflect your day’s meals and workouts. 

When should you NOT take your ACEs measurement? 

For the most accurate results, the contact between the Biosense sensor and your breath should not be compromised.  

Expert Tip: This means you should refrain from measuring for at least 1 hour after you’ve: 

• Eaten food 
• Consumed alcohol, sodas, or flavored waters 
• Smoked or vaped 
• Used toothpaste or mouthwash 

• Chewed gum or breath mints 
• Exposure to aromatics and solvents like cleaners, perfumes, hand sanitizers, or nail polish remover may also affect the quality of your ACEs measurements. Make sure your environment is clear of any such exposures before taking a measurement.

The Ketone Dose is a summary of how long and how deeply you’ve been in a fat burn state (ketosis) on any given day. It is estimated from your ACEs measurements. Think of it as the “dose” of ketones your body got for that day.

To see your personalized depth and duration of nutritional ketosis, perform a measurement at least 3-5 times per day with at least 1 hour between measurements. For best results, include a measurement before breakfast, lunch and dinner. To learn about how different foods and exercise routines affect your individual metabolism, test right before and then again 1 to 3 hours after each meal or exercise session. There is no upper limit to the number of tests per day. Your Biosense® device stores 100 measurements and shows up to 10 measurements in the History, which is accessible via the MENU button. Once you connect your device to the Biosense® app, you can view all your past measurements.

In addition to carbohydrates and fat, ketones represent a third class of energy substrates for your metabolism. Under conditions of carbohydrate restriction, your liver converts fats into the ketones acetoacetate (AcAc) and beta-hydroxybutyrate (BHB), which can be used for energy. Acetoacetate also breaks down into acetone, which is volatile and can be measured in the breath. AcAc and BHB both circulate in the blood and can interconvert within cells. Blood ketone meters measure BHB. Unused AcAc is excreted in the urine where it can be detected using urinary dipsticks. Urine tests provide a range of ketone levels rather than a discrete value. Further, AcAc levels in the urine decline after several weeks of keto-adaptation, which limits the utility of urine strips to track nutritional ketosis over time.

Our ACE unit is approximately 10x the blood ketone value. For example, if the Biosense® device reads 10 ACEs, that corresponds to about 1.0mmol in blood. Keep in mind that this correspondence is dependent upon the individual and on several other factors. For example, blood and breath ketones do not change at the same rate. If you keep these factors in mind, 10x is a good rule of thumb.

Our research shows high correlations between BhB and acetone. One of the key findings was that breath and blood ketones appear to be offset in time, with blood ketones usually changing first followed by breath ketones. You will likely see this with measurements. You may want to experiment…try measuring your blood ketones 1-2 hours before a breath measurement. There are many biological factors that affect the rate and equivalency of ketones.

We recommend waiting to take ketone measurements 1 hour after eating or drinking.

There are two possible reasons why your Biosense device may occasionally ask you to Try Again.

1. If the device was not able to fully prepare the sensor to receive a breath sample, you will see a Try Again message. After this message, Biosense® will perform additional sensor preparation steps.
2. If the device does not detect a breath at the Blow screen, you will see a Try Again message. This can happen if you blow too gently or if you simply forget to blow. After the Try Again message, Biosense® will revert back to the Press Start screen where you can attempt another breath sample.
3. The alcohol in the hand sanitizer and the acetone in the nail polish remover can interfere with the Biosense® sensor and trigger a Try Again message. You should avoid using the Biosense® device immediately after using these products.

Blood and breath ketones are different. The short answer to this question is not always. To find out more check out our article about the differences and similarities of breath, blood and urine ketone measurements.

The condensation that appears is from the moisture of your breath. This is very common with the Biosense® device and the moisture should disappear after time. This does not affect the performance of the device. If you find that the markings do not disappear after each use please reply back to our support team and we will investigate further.

If your device determines that extra sensor warmup or clearing is necessary, it will automatically activate the Smart Clean process. Periodic Smart Clean activations are a normal part of regular device use and do not indicate device malfunction.

Please, remember solvents like hand sanitizer, nail polish remover, and other aromatics may react with the sensor and force the device into this cycle.

On your device select Settings, scroll down to Clean, and select. This process takes approximately 10 minutes to complete and requires your device to be plugged into the charger.

To power off your Biosense® device press and hold the Start button for about 12 seconds. You can power off your device from any screen. To power back on, press and hold the Start button for about 3 seconds.

An overly gentle blow may not be detected. Make sure you are blowing with moderate strength. Continue blowing until you feel two short vibrations, which signals that a breath sample has been correctly obtained. If the device continues to report ‘Blow Undetected’, please, perform a Hard Reset. Press and hold the Checkmark/Start button for 13 seconds. You will see the logo disappear. Once the device is reset, press the checkmark button once more for 3 seconds until you see the Biosense® logo. Then, take a ACEs measurement.

If Biosense® does not detect your blow after three attempts, reset the device by holding the start (check mark) button on the device until the screen is off.

Make sure you have previously paired your Biosense® device to the app (See: How do I pair my Biosense® device to the app?). In order to sync data, the app and device must be paired and the app must be open. If device and app are paired and the app is open, the Biosense® device will send all previously unsent data to the app upon device wakeup AND after a measurement is taken.

Android/iOS If you are having difficulty pairing your device with the Biosense® app, turn off Bluetooth in your phone’s settings and close the Biosense® app. Go back to your phone’s settings and turn Bluetooth back on.
