Secondary / Primary Bile Acids (Ratio)
This ratio reflects the conversion of primary bile acids by gut bacteria into secondary bile acids. A higher ratio may indicate increased microbial conversion or slowed bile acid turnover, while a lower ratio can indicate reduced bacterial activity or impaired bile flow. Maintaining balance is important for gut–liver communication, lipid metabolism, and overall digestive health.
Description
This ratio indicates how efficiently intestinal bacteria transform primary bile acids into secondary bile acids. It offers insight into the relationship between the gut microbiota and liver metabolism.
A higher ratio may suggest increased bacterial conversion, reduced bile acid turnover, or changed intestinal reabsorption. It can also arise in instances of microbial overactivity or impaired bile acid clearance.
A lower ratio may indicate reduced bacterial activity, the use of antibiotics, or impaired bile flow from the liver. It can also suggest decreased microbial diversity or alterations in gut-liver communication.
Maintaining a diverse gut microbiota, ensuring adequate hydration, and consuming sufficient dietary fibre can support healthy bile acid metabolism. Supporting liver function and avoiding excessive intake of processed fats also helps preserve a balanced ratio.

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 Europe. 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.
