Urticaria Histamine Release Test

Urticaria Histamine Release Test

The urticaria histamine release test refers to a specialised diagnostic method designed to detect chronic urticaria (hives) brought on by histamine release. This test is essential for identifying the leading cause of ongoing skin reactions. It also helps develop effective treatment strategies.

What is Histamine Releasing Urticaria?

Histamine-releasing urticaria is a condition in which the immune system triggers the release of histamine, resulting in the appearance of hives or welts on the skin. Idiopathic (unknown) factors, autoimmune responses or allergies could be the cause of this reaction.

Why Is Urticaria Histamine Release Test Performed?

The urticaria histamine release test is usually suitable for those having chronic or unexplained hives or welts. Symptoms prompting this test may involve:

  • Recurrent itchy, red, or elevated welts on the skin.
  • Angioedema (swelling of the skin).
  • Flare-ups prompted by stress, heat, pressure or certain foods.
  • Hives that persist for over six weeks.

How Urticaria Histamine Release Test Work

  • Blood sample collection: This involves drawing a small blood sample from the vein, often in the arm.
  • Lab examination: Analysing the sample to check histamine release and identify any immune system triggers.

Interpreting Results

  • Positive results: Signify histamine release is the reason for chronic urticarial and is possibly linked to autoimmune or allergic reactions.
  • Negative results: Indicate the need for additional diagnostic testing in order to investigate other possible causes like mast cell disorders or allergen sensitivities.

Preparation and Risks

Preparation:

No distinctive preparation is required for this test. However, it’s important to tell your GP about any drugs you’re taking, particularly antihistamines, since these may affect the test results.

Risks:

The risks associated with this test are minimal and may include discomfort or mild bruising at the blood collection site.

Advantages of the Urticaria Histamine Release Test

  • Reliable diagnosis: Identifies histamine’s involvement in persistent hives.
  • Customised care: Assists your medical professional in developing a focused treatment strategy.
  • Better quality of life: Reducing symptoms and enhancing day-to-day living can be achieved by determining and treating the root cause of the problem.
