A tryptase level test measures the amount of tryptase, an enzyme released by certain immune cells called mast cells, in your blood. It is usually ordered to help evaluate severe allergic reactions, repeated flushing or hives, or a suspected mast cell disorder.

What it measures

  • Total tryptase — The overall amount of tryptase enzyme in your blood.
  • Baseline tryptase — A level taken when you are well, used for comparison over time.
  • Acute tryptase — A level taken soon after symptoms, which may be higher during a reaction.
  • Tryptase change over time — How much the level rises or falls between samples.

Who it is for

Tryptase testing is typically ordered by allergists, immunologists, emergency or internal medicine clinicians, and other specialists evaluating severe allergic reactions or possible mast cell conditions.

Preparation

No fasting is usually required. Timing matters: your clinician may ask for a sample during or shortly after symptoms and another sample later when you feel well, so follow the specific timing instructions you are given.

Results and what they mean

Results are reported as a number, often in nanograms per milliliter (ng/mL), and may be compared with a previous sample or a reference range. A single value does not confirm or rule out a condition; a clinician interprets it alongside your symptoms, timing, and other tests. This is general information only and not medical advice.

Frequently asked questions

Do I need to fast for a tryptase test?

Fasting is not usually needed. Ask your clinician if any other tests on the same day require fasting.

Why might I need more than one tryptase sample?

Comparing a sample taken during symptoms with one taken when you are well can show whether tryptase rises during a reaction.

What can affect my tryptase result?

Timing of the sample, recent allergic reactions, and some other health conditions can affect the level. Tell your clinician about recent symptoms and medicines.

How long do results take?

Results are commonly available in about 1 to 3 business days, though this can vary by laboratory.
