Tryptase

Optimal Result: 2.2 - 13.2 ug/L.

This test measures the amount of tryptase in the blood.

Other names: 

- Mast Cell Tryptase 

- Alpha Tryptase 

- Beta Tryptase 

- Mature Tryptase

Tryptase is an enzyme that is released, along with histamine and other chemicals from mast cells when they are activated as part of a normal immune response as well as in allergic responses. 

What are mast cells?

Mast cells, which are granulocytes found in peripheral tissue, play a central role in inflammatory and immediate allergic reactions. 

They are present in the highest amounts in:

- the skin 

- the lining of the intestine

- air passages, 

- and the bone marrow

They contain granules (=particles) that store a number of chemicals, including tryptase and histamine. When mast cells are activated, they release their contents. If a person has too many mast cells (=mastocytosis) and/or the cells are activated inappropriately, the chemicals that are released (especially histamine) may cause symptoms that range from moderate to life-threatening.

Normal conditions:

Normally, the level of tryptase in the blood is very low.

What does it mean if your Tryptase result is too high?

- When mast cells are activated, the level increases rapidly, rising within 15 to 30 minutes, peaking at 1 to 2 hours, and returning to normal after several hours to a couple of days. In people with severe allergies, activation of many mast cells can cause an extreme form of allergic reaction (=anaphylaxis), which can cause low blood pressure, hives (blisters on the skin), severe narrowing of the air passages, and even death. Tryptase levels will be very high in people with anaphylaxis.

- In some cases, tryptase levels will be high in persons with mast cell activation disorders, in which mast cells become activated without apparent allergies or other reasons.

- Tryptase levels can also be significantly and persistently increased with mastocytosis, a rare group of disorders associated with an abnormal increase in the number of mast cells. These cells may accumulate in the skin (=cutaneous mastocytosis) or in organs throughout the body (=systemic mastocytosis).

Symptoms:

While cutaneous mastocytosis typically only causes skin problems (particularly hives), people with systemic mastocytosis or a mast cell activation disorder may experience anaphylaxis and its associated symptoms. These symptoms may be persistent and are related to the organs affected by mast cell accumulation. Systemic mastocytosis may progress slowly or may be aggressive, causing organ dysfunction and, in rare cases, causing a form of leukemia.

Tryptase Levels in Clinical Practice

Tryptase is a enzyme primarily released by mast cells, making it a valuable biomarker for mast cell activation and mast cell disorders. In clinical practice, elevated tryptase levels are typically of more concern than low levels, as they often indicate significant mast cell activation or underlying disorders.

Normal Tryptase Levels

The normal range for serum tryptase is generally considered to be 1-15 ng/mL. Levels below this range are not typically flagged as abnormal or clinically significant. Sample timing is crucial, as levels can fluctuate throughout the day and in response to various stimuli.

Low Tryptase Levels

There is limited scientific evidence regarding the clinical significance of low tryptase levels. Some key points to consider:

  1. Biological Variation: Tryptase levels can vary naturally between individuals. Studies have found that serum tryptase has very low within-subject variation (3.7%) but considerable between-subject variation (31.5%).
  2. Lack of Clinical Significance: Low tryptase levels are generally not considered clinically significant on their own and do not necessarily indicate a health problem.
  3. Mast Cell Disorders: In the context of mast cell disorders, tryptase levels are typically elevated rather than low. However, baseline levels are important for comparison during acute events.
  4. Anaphylaxis: While elevated tryptase can be indicative of anaphylaxis, low levels do not rule it out. The change in tryptase levels during an acute event compared to baseline is more informative than the absolute value.
