Testing for Alpha-Gal

Clinicians typically order a blood test measuring IgE to galactose-α-1,3-galactose (“alpha-gal”). Major labs include Labcorp and Quest. Always discuss testing and results with a board-certified allergist.

Find testing locations

Use the lab location finders to schedule a nearby blood draw (most don’t require fasting). These tools do not expose public APIs, so we link directly to their official finders:

• Labcorp Locations
• Quest Diagnostics Locations

Direct-to-consumer option

Some users prefer to purchase the test directly and bring results to their clinician. Availability varies by state. Always pair results with clinician guidance.

Find an allergist

Board-certified allergists can help interpret results and manage alpha-gal syndrome.

Important context

• Tick presence maps do not equal guaranteed risk, but they correlate with alpha-gal hotspots. See our map and CDC overview.
• Test interpretation should consider clinical history, exposures, cofactors, and timing of reactions.
