Cairn Diagnostics

Test with Confidence. 
CAIRN Diagnostics 13C-Spirulina Gastric Emptying Breath Test (GEBT) is intended for use in the measurement of the rate of gastric emptying of solids and as an aid in the diagnosis of delayed gastric emptying (gastroparesis) in adults. GEBT is now guideline recommended for the diagnosis of gastroparesis.  It is an FDA-approved, non-radioactive, non-invasive, orally administered, standardized test. GEBT was validated against the 4-hour gold standard reference method of gastric scintigraphy.  GEBT can be administered in the physician’s office or “at-home” virtually through Cairn’s FDA approved telehealth program.  Breath samples are sent by overnight courier to Cairn’s CLIA clinical laboratory and analyzed. Results are sent within 24-48 hours to the ordering physician through a secure online portal. GEBT has received a dedicated CPT code and Medicare reimbursement.
