The testing was quite easy and showed that pepsin was present. Therefore a positive test. I took the results to my doctor who disregarded the test and said she would have to read the letters i was sent and ask further professionals if they consider it. So my experience follwing the test has got me no further forward with this.
Beverley C. (verified owner) –
The test arrived quickly and well packaged. The instructions were easy to follow and the results were back within a week. After several tests by my Gp which all came back negative, I was pleased to have this professional test result to support my case that something is wrong with my digestive tract. My Gp has read the letter and I’m awaiting a referral to the hospital for more specific investigations. I’m so pleased that I found Peptest, thank you

It really helps to be able to narrow down the cause of one’s symptoms. Very easy to carry out.
Duncan (verified owner) –
Delivery was fast, results were super fast. The process is straightforward. I hope I have some evidence now to be heard by my GP and ENT.

Clear easy instructions. Helped me to understand when my symptoms were more severe
Philippa (verified owner) –
Fantastic service. Clear easy instructions and really quick results, which I appreciated. After months of doctors telling me I didn’t have reflux, I had proof and certainty that I did have it and how severe it was, through the peptest.
Once I cleared the SIBO that was causing the reflux the pep test was again great to remove my anxiety that it was still happening by confirming negative tests. Excellent. Thank you.

It confirmed that pepsin was the problem which made it possible for me to eliminate all acid from my diet for about 3 weeks and stop the annoying perpetual cough the pepsin in my throat was causing

The test was easy to administer and I received the results quickly. Now I can take proper action. I would say don’t wait for doctors instead be actively engaged with trying to get a diagnosis. I wish I knew sooner about the Peptest!

I waited a long time for my results. They probably ended up in my spam folder. However, I received the test results immediately after inquiring.
The test procedure was simple.
