Ochratoxin A is a mycotoxin produced by certain Aspergillus and Penicillium species, which are fungi that can grow in damp or poorly ventilated spaces. This toxin can persist on indoor surfaces long after mold growth is removed. SimpleLab’s Ochratoxin A Mycotoxin Surface Wipe Test provides specialized, laboratory-based analysis for a surface wipe sample, helping you confirm whether residues remain in your environment.

How to Test for Ochratoxin A the Right Way

Testing for mycotoxins like ochratoxin A requires certified laboratory analysis. This mail-to-lab kit includes everything needed to collect a single wipe sample, ship it safely, and receive a verified result. 

Each kit includes: 

  • Sampling materials
  • Prepaid 2-day return shipping
  • Clear, easy-to-follow instructions

Once received at the laboratory, your sample is analyzed using LC-MS/MS (EMSL Method)—a highly sensitive technique capable of detecting ochratoxin A at levels as low as 0.005 µg/wipe.

Who Should Use This Test

This test is ideal for homeowners, building managers, or remediation professionals who suspect or have remediated mold growth from Aspergillus or Penicillium species and want to ensure surfaces are clean and safe.

Frequently Asked Questions

Can I use DIY test strips for mycotoxins?

No. Mycotoxin detection requires sensitive lab instrumentation like LC-MS/MS. At-home test strips cannot provide reliable or quantitative results.

Where should I collect my surface wipe sample?

Common sampling areas include HVAC returns, drywall, furniture surfaces, or spaces previously affected by water damage or visible mold.

How long will it take to get results?

Shipping to the lab takes about two days, and laboratory analysis is completed within ten business days. Results are delivered digitally through your secure SimpleLab dashboard.
