Is there a blood test for histamine intolerance?

Histamine Intolerance Test

At this time there are no proven tests to diagnose histamine intolerance. A trial of a low histamine diet is used to determine the presence of histamine intolerance. It is possible to measure blood DAO activity (one of the enzymes listed above), and histamine levels.

What does a high histamine level mean?

Bacterial overgrowth is another contributing factor for developing a histamine intolerance. Bacteria grows when food isn’t digested properly, causing histamine overproduction. Normal levels of DAO enzymes can’t break down the increased levels of histamine in your body, causing a reaction.

What is a normal histamine level?

Because some nor- mal individuals had values greater than 13.5 ng/mL, we considered a higher value for defining elevated total tryptase values as being greater than 15 ng/mL. The normal range for histamine (≤10 nm/mL) was obtained from the manufacturer.
