Histamine-producing bacteria
Histamine-producing bacteria are gut microbes capable of converting the amino acid histidine into histamine, a biogenic amine that plays a central role in immune responses and allergic reactions. While histamine is a necessary signaling molecule, excess production in the gut can contribute to symptoms resembling allergies, such as rashes, headaches, or digestive discomfort. These bacteria may thrive in the presence of chronic stress, poor gut barrier function, or diets rich in histidine-containing foods. Elevated levels are associated with conditions like histamine intolerance or pseudoallergies. Maintaining a balanced microbiome and proper gut barrier integrity may help reduce histamine load from microbial sources.
Description
These are specific gut microbes that convert the amino acid histidine into histamine, which can affect immune function and inflammatory responses.
Excessive histamine production by gut bacteria can contribute to symptoms such as bloating, skin reactions, headaches, or food intolerances, even in the absence of a typical allergy.
A high percentage indicates an overgrowth of histamine-producing bacteria, which may suggest dysbiosis, increased intestinal permeability ("leaky gut"), or histamine intolerance.
It indicates that these microbes are neither currently overactive nor abundant, which could be beneficial for people with histamine sensitivity.
Diet, chronic stress, and microbial imbalance in the gut all contribute. Reducing histamine-rich foods and enhancing gut health may help regulate histamine production.

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 USA. 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.
