Histamine (Blood)
The Histamine (Blood) test measures the level of histamine circulating in the bloodstream. Histamine is a naturally occurring chemical released by immune cells and plays an important role in allergic reactions, inflammation, and regulation of stomach acid.
In some individuals, histamine levels may become elevated or poorly regulated, contributing to symptoms such as flushing, headaches, itching, hives, nasal congestion, digestive discomfort, or unexplained allergic-type reactions.
This test is often used when histamine intolerance, mast cell activation, or unexplained allergy-like symptoms are suspected. It may also be requested as part of a broader investigation into chronic inflammatory or allergic conditions.
Because histamine levels can fluctuate and may be influenced by diet, medications, and stress, results are always interpreted alongside symptoms, clinical history, and other relevant investigations.
