Desulfomonas pigra
Desulfomonas pigra is a species of sulphate-reducing bacteria (SRB) found in anaerobic environments, including the human gut. It plays a role in sulphur metabolism by reducing sulphate to hydrogen sulphide (H₂S). While hydrogen sulphide is a naturally occurring compound in the colon, elevated levels produced by SRBs like D. pigra can disrupt intestinal barrier function and contribute to gastrointestinal inflammation or discomfort. Increased abundance of Desulfomonas pigra may indicate an overgrowth of sulphur-reducing microbes, potentially associated with diets high in sulphur-containing foods or imbalances in gut microbiota.
Description
It is a sulphate-reducing bacterium in the gut that produces hydrogen sulphide as part of its metabolism.
To assess levels of sulphur-reducing bacteria that may contribute to gut dysbiosis or inflammation.
It may suggest excessive sulphur metabolism in the gut and a possible imbalance in the microbial composition.
In high amounts, it can produce excessive hydrogen sulphide, which may damage the gut lining and promote inflammation.

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the UK. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

Absolutely perfect, results came after few days and finally after a lots of times visited GP, we finally know why my son has eczema - he is allergy to carrot. Thanks a lot.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.
