Fraction of Exhaled Nitric Oxide (FeNO)

The experts at Carolina Diagnostic Solutions offer a wide range of screening and diagnostic devices for asthma care to provide comprehensive and easy-to-use testing in conjunction with spirometry.

Our primary goal is to increase the quality of care provided and, in turn, the quality of life for the patients we serve.

We work directly with healthcare organizations and primary care physicians to train employees to maximize pulmonary care for patients.


Asthma: it's all about the inflammation

Asthma is caused by airway inflammation, but conventional tests like spirometry are checking for obstruction rather than inflammation. That's why it is SO important to have FeNO in your practice. (1-3)

More accurate diagnosis and better management (6-8) 
Asthma is seven times more likely when FeNO is >40 ppb (9). Up to a 50% reduction in exacerbations with FeNO. (10)
