Tryptase is an enzyme that is mainly produced by mast cells, which are part of our immune system. These cells help in fighting infections and play a role in allergic reactions. Tryptase can serve as a biomarker to measure the activity of mast cells in the body.
Tryptase testing can be useful when there is a suspicion of mastocytosis, a rare condition where there is an abnormal accumulation of mast cells in the body. This can also be relevant after a severe allergic reaction, to assess the involvement of mast cells.
A tryptase test can help in diagnosing mastocytosis and other conditions that affect mast cell activity. It can also be used to evaluate the risk of severe allergic reactions.
A high level of tryptase in the blood may indicate mastocytosis, an increase in mast cells due to an allergic reaction, or be an indication of another medical condition affecting mast cells.
A low tryptase level is generally considered normal and indicates that there is no increased activity of mast cells in the body.
Answers to what people usually want to know.
After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.
Usually very quickly. Collection points typically have slots within a few days, sometimes even same-day. It depends on how busy the location is. For a few specialist analyses we first ship collection materials, which takes a bit longer.
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.

That depends on the test. Whether fasting is required, and from what time, is clearly stated in the instructions you receive after ordering. No surprises at the counter.
It varies per analysis: from same-day to a few working days. Standard values often come back quickly; analyses that go to an external lab can take a bit longer. You get an email with a link to your digital result, including a short explanation per value.
We work with 1,000+ collection points across the Netherlands. After ordering you'll see which locations near you are available and you pick where you'd like to go.
