Tryptase Blood Test

Mast Cell Tryptase


Test Code: 004280
Specimen Type: Blood

Description:

Tryptase Blood Test

This test measures the level of Tryptase in the blood.  Tryptase is an enzyme that is released by mast cells as part of the body's normal immune response or when someone is having an allergic reaction.  Mast cells also release Histamine, a chemical that causes allergy symptoms.  If a person has mastocytosis, a condition in which they have too many mast cells, the release of high levels of histamine during an allergic reaction can cause anaphylaxis.  Anaphylaxis can cause lowered blood pressure, hives, narrowing of the airways, and may become fatal.  Other conditions can cause mast cells to release chemicals without proper stimulation.  Measuring tryptase levels when a person is having severe allergy symptoms can help to determine if their condition is caused by mastocytosis or mast cell activation disorder.

 A Tryptase blood test may be ordered when a person has symptoms of anaphylaxis, especially when these symptoms do not seem to be caused by an obvious trigger.  Other tests such as a CBC, CMP, and specific allergen blood tests are often ordered at the same time.

Turnaround for this test is typically 3-5 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.

Requirements:

Samples for this test should be collected as soon as possible after experiencing allergy-related symptoms.

Tryptase Blood Test

This test measures the level of Tryptase in the blood.  Tryptase is an enzyme that is released by mast cells as part of the body's normal immune response or when someone is having an allergic reaction.  Mast cells also release Histamine, a chemical that causes allergy symptoms.  If a person has mastocytosis, a condition in which they have too many mast cells, the release of high levels of histamine during an allergic reaction can cause anaphylaxis.  Anaphylaxis can cause lowered blood pressure, hives, narrowing of the airways, and may become fatal.  Other conditions can cause mast cells to release chemicals without proper stimulation.  Measuring tryptase levels when a person is having severe allergy symptoms can help to determine if their condition is caused by mastocytosis or mast cell activation disorder.

 A Tryptase blood test may be ordered when a person has symptoms of anaphylaxis, especially when these symptoms do not seem to be caused by an obvious trigger.  Other tests such as a CBCCMP, and specific allergen blood tests are often ordered at the same time.

Turnaround for this test is typically 4-8 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
