MethChek 50 Results
MethChek® 50 Kits are semi-quantitative immunoassay tests that detect low levels of methamphetamine residue on surfaces at the lowest state cleanup guideline of 0.05 µg/100cm2 (other sensitivities are available). The kits may be used to determine the need for cleaning in a specific area or the need for further cleaning on-site to reach state cleanup guidelines. Some states and counties require lab results from quantitative wipe sampling before issuing a re-entry certificate. Consult state meth cleanup guidelines.

Combine MethChek with MethAlert™ for easy pre-assessment and cleanup plan development.
Using MethChek 50 Results
MethChek 50 is ideal for health department inspectors and industrial hygienists. Below are just some of the applications:
- Pre-cleanup assessment of clandestine methamphetamine lab sites to determine areas of minimal contamination versus areas of heavy contamination
- Aid the consultant in creating a cleanup plan
- Determine the appropriate level of PPE for the cleanup crews
- Immediate post-cleanup assessment to determine if cleanup crews can be released or if more cleaning is required to reach state cleanup levels
