What is this test?

The Amylase-Triggered Leukotriene Release Test measures the amount of leukotrienes (inflammatory chemicals) released by your white blood cells when stimulated with amylase. Leukotrienes are signaling molecules that play a key role in inflammation, allergic reactions, and immune responses. This test helps doctors understand how your immune cells respond to specific triggers.

How is the test performed?

A healthcare professional will draw a small blood sample from a vein in your arm. The blood sample is then sent to a laboratory where white blood cells are separated and exposed to amylase. Technicians measure the leukotrienes released by these cells. The entire process is similar to a routine blood test and typically takes only a few minutes to collect the sample.

What do the results mean?

High levels of leukotriene release indicate that your white blood cells are hyperresponsive and may be involved in allergic reactions or inflammatory conditions. Normal or low levels suggest normal immune cell function. Your doctor will interpret the results based on your symptoms, medical history, and other test results.

Are there any risks?

The risks are minimal and similar to routine blood tests, including slight bruising, bleeding, or infection at the puncture site. Some people may feel lightheaded during or after the blood draw. These risks are generally temporary and resolve quickly.
