A genetic test to see if your body is predisposed to mold toxicity.

Availability
Available in all U.S. states except Arizona, New York, New Jersey, Hawaii, and Rhode Island.

What it measures

• HLA-DR/DQ gene variants – These determine how well your immune system can recognize and clear mold toxins.
• Identifies if you are among the ~24% of people genetically susceptible to mold-related illness.

Why it matters
Your genetics play a huge role in recovery. If you carry mold-susceptibility genes, your body has difficulty clearing toxins, meaning symptoms can persist even after you leave exposure. Knowing this helps explain why some patients don’t improve without targeted treatment.

How it works

1. Order your test online
2. Receive your requisition
3. Visit a nearby Labcorp location for your blood draw
4. Get detailed results within 2-3 weeks
