Diagnostic testing at U-Breathe


Pulmonary Function Test

The test consists of a series of non-invasive breathing maneuvers to objectively measure how well the lungs are working.


Methacholine Challenge Test
The test consists of a series of non-invasive breathing maneuvers while a small amount of inhaled medication (Methacholine) is given to test for reactive airways.


Fraction of Exhaled Nitric Oxide

A test that measures the level of nitric oxide gas in an exhaled sample of your breathe.


Arterial Blood Gas 
The test is used to check how well the lungs are able to move oxygen into the blood and remove carbon dioxide. It is a blood test that measures the acidity, levels of oxygen (O2) and carbon dioxide (CO2) from an artery.


Cardio-Pulmonary Exercise Test
The test consists of controlled exertion while monitoring breathing and vitals.


The 6 Minute Walk Test gives the doctor an objective measure of your functional capacity. It measures the distance that you can walk quickly on a flat hard surface in a period of 6 minutes. Your oxygen level is monitored during this test.

6 Minute Walk Test


Spirometry is a physiological test that measures inhaled and exhaled volumes of air as a function of time. It is just one component of a complete pulmonary function test. 



This is measurement of breathing muscle strength using measurements of maximum inspiratory pressure (MIP or PImax), and maximum expiratory pressure (MEP or PEmax).

Maximum inspiratory pressure  and Maximum expiratory pressure 


Bronchoscopy is a procedure that looks inside the lung airways. It involves inserting a bronchoscope tube, with its light and small camera, through your nose or mouth, down your throat into your trachea, or windpipe, and to the bronchi and bronchioles of your lungs.



In a level 3 sleep study (a home sleep study) a small machine is used in the comfort of your home at night to monitor oxygen saturation, heart rate, air flow and effort while also recording details about snoring and position. It will help your doctor diagnose obstructive sleep apnea and even assess severity.
