What is this test?
The Bahia grass triggered histamine release test is a specialized blood test used to diagnose an allergy to Bahia grass. When someone is allergic to a substance (allergen), their immune system reacts by releasing chemicals like histamine. This test measures the amount of histamine released when your blood is exposed to Bahia grass allergens in a laboratory setting.
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 it is mixed with Bahia grass allergens. If you are allergic to Bahia grass, your blood cells will release histamine in response. The laboratory measures this histamine level to determine whether you have an allergy.
Why might I need this test?
You may need this test if you experience symptoms of grass allergy, especially during seasons when Bahia grass is prevalent. Common symptoms include sneezing, runny nose, itchy eyes, nasal congestion, and asthma-like symptoms such as wheezing and shortness of breath. This test helps identify whether Bahia grass is the specific trigger for your allergic reactions.
Reference range
Negative: < threshold value indicating no significant histamine release above baseline; positive results reported as quantitative units/volume or as percent histamine release relative to control. Reference values vary by laboratory and allergen concentration used.N/A
No fasting required. Patients should inform their healthcare provider of all current medications, particularly antihistamines, corticosteroids, and leukotriene modifiers, as these may suppress histamine release and lead to false-negative results. Discontinuation of antihistamines should be discussed with the ordering physician prior to testing.
