Biometry is an easy to use breath test for asthma

Sensor + Device + App


Find the Right Medication

Not all patients respond to inhaled steroids, and the wrong medication or dose is just as costly as poor adherence.

Test Adherence

Determine if the cause of symptoms or attacks is related to misuse of inhaler, adherence, ineffective dose, or the wrong medication.

Monitor Risk of Attack

Just because patients don't have symptoms doesn't mean they're not at risk. Over 82% of patients who have severe asthma attacks think their disease is controlled.1


What we measure

FeNO, a biomarker of airway inflammation that is reduced by anti-inflammatory medications. Elevated levels indicate risk of an asthma attack that is independent of symptoms. The biomarker was added to the Global Initiative for Asthma Guidelines in 2017.



Over 82% of patients who had a severe asthma attack thought their disease was controlled.1

Biometry changes perceptions about asthma severity by showing patients when they are at risk for an attack regardless of symptoms.

Biomarker is elevated. Patient is at risk of having an attack even if they don't have symptoms.


Patients understand they need to use their controller medications even if they feel fine.


Biomarker levels are reduced within 1 day. Patients can visualize the anti-inflammatory effect of the drug and how it reduces risk of an attack. 


Physicians and Payers

Most patients don’t adhere to asthma therapy. When patients do use their inhalers, over 70% make a critical error that prevents the drug from reaching their lungs and having a therapeutic effect.2 This leads to poorly controlled asthma which costs between $893 and $7,138 per patient per year depending on severity.3,4

Physicians don’t know if asthma symptoms and attacks are caused by non-adherence, misuse of inhaler, or disease severity requiring more potent drugs. This results in approximately 50% of medical treatment being either unnecessary or preventable.1-5

Biometry's data provides objective information to physicians to prevent attacks and reduce unnecessary treatment.
