What it measures
- HLA-DR/DQ gene variants.
- How well your immune system can recognize and clear mold toxins.
- Whether you are among the ~24% of people genetically susceptible to mold-related illness.
Why it matters
The result can help explain why the same water-damaged building affects people differently. If you carry mold-susceptibility variants, the next question is usually whether your current symptoms and biomarkers fit the same pattern.

Before you order
These answers keep the HLA result in the right lane: susceptibility context, not a standalone diagnosis.
Does HLA-DR mean I will get sick from mold?
No. It helps explain susceptibility, not certainty. Exposure level, health history, and total clinical context still matter.
Do I need to repeat HLA testing?
No. HLA type is genetic context and does not change over time.
Add the genetic piece once
Use the result as durable context alongside exposure history, symptoms, blood markers, and provider guidance.
