Calibration Information
Drugs of Abuse (DOA) Assays
Ethanol
The Ethanol assay is a quantitative assay and uses the Ethanol
0 and 100 calibrators.
Qualitative Assays
Calibration of the qualitative DOA assays is performed by
running the calibrators in duplicate. The Multi DOA Cutoff
calibrator is configured as “0” (zero) in the Target Value field of
the
CALIBRATOR/CONTROL
screen for the
Amphetamine/Methamphetamine, Barbiturates,
Benzodiazepines, Cannabinoids (THC50), Cocaine,
Methadone, Opiates 2,000, Phencyclidine, and Propoxyphene
assays. The Opiates 300 calibrator is configured as “0” (zero)
for the Opiates 300 assay.
For Amphetamine/Methamphetamine, Barbiturates,
Benzodiazepines, Cannabinoids (THC50), Cocaine,
Methadone, Opiates 300, Opiates 2,000, Phencyclidine, and
Propoxyphene assays, any result value equal to or greater than
the Multi DOA Cutoff calibrator is positive; the specimen
contains drug. Any result below the cutoff level for the assay
being tested is interpreted as negative; the specimen does not
contain drug, or drugs present yield a response less than that
of the cutoff calibrator for the assay being tested.
The calibration is verified by running Multi DOA Verifiers I
and II (recommended) and controls. Two levels of controls
should also be run, with one control level 25% above the
cutoff concentration and the other control level 25% below
the cutoff concentration. Verifiers I and II and control results
should show appropriate responses relative to one another, as
shown:
Verifier I < – 25% Control < Cutoff Calibrator < + 25% Control < Verifier II
