A trial of a low histamine diet is used to determine the presence of histamine intolerance. There are currently no proven tests to diagnose histamine intolerance. It is possible to measure blood DAO activity (one of the enzymes listed above), and histamine levels. These results do not seem to correlate with symptoms.
What are the symptoms of high histamine levels?
Symptoms of histamine intolerance
- headaches or migraines.
- nasal congestion or sinus issues.
- digestive issues.
- irregular menstrual cycle.
Can you test for histamine levels?

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.
What triggers histamine release?
Histamine release occurs when allergens bind to mast-cell-bound IgE antibodies. Reduction of IgE overproduction may lower the likelihood of allergens finding sufficient free IgE to trigger a mast-cell-release of histamine.
What foods should I avoid with histamine intolerance?

- fermented dairy products, such as cheese (especially aged), yogurt, sour cream, buttermilk, and kefir.

Does exercise increase histamine levels?
Both tryptase and histamine concentrations increased during exercise, supporting the idea that mast cells are an important source of histamine responses to exercise in humans. The stimulus for the release or synthesis of histamine by specific cells in skeletal muscle in response to dynamic exercise is still unknown.
Does stress cause high histamine levels?
When you’re all stressed out, your body releases hormones and other chemicals, including histamine, the powerful chemical that leads to allergy symptoms. While stress doesn’t actually cause allergies, it can make an allergic reaction worse by increasing the histamine in your bloodstream.
