A rapid DOT look-alike is a test that closely mimics the drugs & cut-off levels of the industry standard laboratory DOT drug test. For a rapid test to be considered a look-alike, it must match all of the DOT drugs and must have cut-off levels that are equal to lower than the DOT levels. Labb has created a 28-pt scale that outlines the rapid test requirements for being a true DOT look-alike.
Laboratories generally group certain drugs together regardless of the test type being a "DOT look-alike" or not. Laboratories, like the DOT, group Opiates & Amphetamines into classes with specific drugs & specific cut-off levels for each. In rapid testing, many of the drugs the laboratories consider a single drug group are actually multiple rapid drug test assays. In total, there are 14 specific analytes that comprise the DOT test-panel requirement.
In rapid drug testing, there are target analytes & cross-reactions. Many of the Opiate & Amphetamine tests that target a specific analyte, also detect alternate Opiates & Amphetamines through cross-reactions. For example, the rapid test for HMO or Hydromorphone has a greater affinity to detect Oxymorphone than the OXY or Oxycodone assay. The Oxymorphone, Hydrocodone & Hydromorphone DOT requirement are satisfied on the UA:10C and 16C is using a single test assay for HOM or Hydromorphone. With Labb's special UA Series rapid tests, all 14 drugs of the DOT can be detected using only 10 rapid drug test assays.
