Portable FeNO Monitoring System Approved for a 6-Second Breath Test
~ St. Paul, MN (FEBRUARY 27, 2026) — MGC Diagnostics, a leading provider of cardiorespiratory diagnostic solutions, today announced the U.S. availability of Fenom Flo™, the only portable FeNO device approved for a 6-second breath test in adults and pediatric patients ages 7 years and older. By combining a shorter breath test with a handheld, point-of-care design, Fenom Flo supports objective measurement of fractional exhaled nitric oxide (FeNO) in more patients and across more care environments.
Fenom Flo provides non-invasive, point-of-care FeNO measurement to support respiratory assessment using a simple breath maneuver. The shorter, approved 6-second breath test helps enable testing in patients who may struggle with longer exhalations, including pediatric and other difficult-to-test populations.
“The U.S. launch of Fenom Flo represents an important expansion of our respiratory diagnostics portfolio,” said Raul Carreras, President of MGC Diagnostics. “By combining an FDA-approved 6-second breath maneuver with true portability, Fenom Flo supports point-of-care FeNO testing and reflects our commitment to delivering clinically meaningful innovation for real-world care settings.”
Unlike traditional FeNO systems that may rely on longer breath maneuvers or fixed laboratory setups, Fenom Flo is designed for use at the point of care, including exam rooms and outpatient clinics. Its compact, handheld design allows clinicians to perform FeNO testing during routine patient visits without the need for specimen collection or preparation, supporting respiratory evaluation across a variety of practice settings as an adjunct to established clinical assessment.
The U.S. introduction of Fenom Flo underscores MGC Diagnostics’ continued focus on expanding access to objective respiratory insights through practical, patient-friendly diagnostic solutions.
