The Mandelin Reagent is not designed as a specific field test, but rather a general screening test to direct you to the presumptive field tests for Methadone, Amphetamines or Methamphet-amine. 10 tests/box.

Like all our NARK narcotic field tests, the Mandelin Reagent is meant for presumptive field drug testing.

NOTE: ALL TEST RESULTS MUST BE CONFIRMED BY AN APPROVED ANALYTICAL LABORATORY! The results of this test are merely presumptive. NARK® only tests for the possible presence of certain chemical compounds. Reactions may occur with, and such compounds can be found in, both legal and illegal products. This test must be administered following its specific instructions and may be used in conjunction with other reagents in the NARK® II Sequential Testing System.
