Alpha-Gal blood test measuring IgE antibodies to alpha-Gal and 3 red meat allergens to determine alpha-Gal Syndrome or red meat allergy.
This alpha-Gal panel measures immune responses to alpha-Gal and 3 meats (beef, lamb, pork) that commonly trigger alpha-Gal-associated meat allergy. It's also called tick-bite meat allergy because it typically starts when a tick transmits alpha-Gal, a sugar molecule in mammals. This triggers an immune response, causing reactions after red meat consumption. The test helps identify potential alpha-Gal allergy. A healthcare provider will review results with your medical history to diagnose and prescribe treatment if needed.

No fasting required. Continue eating your normal diet for at least 2–4 weeks before testing — avoiding suspected trigger foods can cause false negatives. Inform the clinic of any antihistamines or immunosuppressants you're taking, as these can affect results.
Biomarkers Tested
4A group of proteins in blood including antibodies (immunoglobulins), transport proteins, and enzymes. Elevated globulin can indicate chronic infection, inflammation, or blood cancers. Calculated by subtracting albumin from total protein.
Immunoglobulin E (IgE) is a protein associated with allergic reactions that is normally found in very small amounts in the blood. IgE functions as part of the body's immune system (its defence against 'intruders').
