MethChek Immunoassay Wipe Kit for
Methamphetamine Residue on Surfaces
Developed by the U.S. National Institute for Occupational Safety and Health (NIOSH), Centers for Disease Control (CDC), MethChek wipe kits identify methamphetamine residue on surfaces at or above relevant state cleanup levels. Ideal for pre and post-remediation evaluation of clandestine meth lab sites, MethChek provides on-the-spot answers without waiting for lab results. MethChek kits are available with a 0.05, 0.1, 0.5, or 1.5 microgram per 100 cm lower limit of identifi cation (LLOI).

pattern
b. Left to right in a “Z”
pattern
Do not trap or push surface residue under edges of template.

Extracting the Sample
1. Insert gauze pad containing sample into syringe.
2. Insert syringe plunger and gently push gauze pad toward base of syringe.
Press enough to loosely compact gauze pad.
3. Remove syringe plunger.
c. Repeat left to right in a
“W” pattern
Insert gauze into syringe.
