Finally, a Reflux Test
You Can Do at Home.
Laryngopharyngeal reflux — sometimes called “silent reflux” — is notoriously hard to diagnose. The symptoms overlap with a dozen other conditions, traditional tests can be uncomfortable and inconclusive, and many people spend years looking for an explanation.
PepsinCheck by Peptest is a different kind of reflux test. You collect a saliva sample at home, ship it back in the prepaid packaging included in your kit, and get laboratory results that can provide real biological evidence of whether reflux is reaching your throat and airway.
No probes. No sedation. No clinic visit or prescription required.
How It Works
PepsinCheck detects pepsin in your saliva. Pepsin is a digestive enzyme produced exclusively in the stomach — so finding it in your saliva is a meaningful signal that stomach contents are reaching your upper airway.
You collect your samples in the simple materials included in the kit, then send them back using the prepaid return package. The samples are analyzed in a certified laboratory using lateral flow technology, the same reliable method used in many modern diagnostic tests.
A positive result provides objective biological evidence of reflux — something that can be difficult to establish through symptoms alone, especially with LPR.
What It Can Help You Understand
PepsinCheck is particularly useful if you’re experiencing:
- Chronic cough
- Hoarseness
- Frequent throat clearing
- Globus sensation (the feeling of something stuck in your throat)
- Shortness of breath
- Sleep disruption related to reflux
- Dental concerns (Enamel erosion)
Having objective evidence of reflux can be a meaningful step toward getting the right answers — and the right care.
Who It's For
PepsinCheck works well for patients who want to investigate their symptoms before or between doctor’s visits, as well as for clinicians looking for a non-invasive diagnostic option to incorporate into an LPR evaluation. It doesn’t replace a full clinical workup, but it can be a valuable piece of the puzzle — especially when standard methods haven’t provided clear answers.
Each kit includes saliva collection materials and prepaid return shipping. Additional information and support are available if you need them.
