Initial test requirements based upon standards adopted by the federal Substance Abuse and Health Services Administration in “Mandatory Guidelines for Federal Workplace Drug Testing Programs,” 88 FR 70768, Section 3.4, and displayed in the following table are hereby adopted as standards for determining detectable levels of controlled substances in a person’s urine in the division of criminal investigation criminalistics laboratory initial testing or analysis for controlled substances detected by the presence of the following: marijuana metabolites, cocaine metabolites, codeine/morphine, hydrocodone/hydromorphone, oxycodone/oxymorphone, 6-acetylmorphine, phencyclidine, amphetamine/methamphetamine, and MDMA/MDA. The following table shows the minimum levels of these substances that will result in a finding that a controlled substance is present at a detectable level:

Initial test analyte

Initial test cutoff1

Marijuana metabolites (THCA)2

50 ng/mL3

Cocaine metabolites (Benzoylecgonine)

150 ng/mL3

Codeine/Morphine

2000 ng/mL

Hydrocodone/Hydromorphone

300 ng/mL

Oxycodone/Oxymorphone

6-Acetylmorphine

10 ng/mL

Phencyclidine

25 ng/mL

Amphetamine/Methamphetamine

500 ng/mL

MDMA4/MDA5

500 ng/mL

1 

For grouped analytes (i.e., two or more analytes that are in the same drug class and have the same initial test cutoff):

Immunoassay: The test must be calibrated with one analyte from the group identified as the target analyte. The cross-reactivity of the immunoassay to the other analyte(s) within the group must be 80 percent or greater; if not, separate immunoassays must be used for the analytes within the group. 

Alternate technology: Either one analyte or all analytes from the group must be used for calibration, depending on the technology. At least one analyte within the group must have a concentration equal to or greater than the initial test cutoff or, alternatively, the sum of the analytes present (i.e., equal to or greater than the laboratory’s validated limit of quantification) must be equal to or greater than the initial test cutoff. 

2 

An immunoassay must be calibrated with the target analyte, D-9-tetrahydrocannabinol-9-carboxylic acid (THCA).

3 

Alternate technology (THCA and benzoylecgonine): The confirmatory test cutoff must be used for an alternate technology initial test that is specific for the target analyte (i.e., 15 ng/mL for THCA, 100 ng/mL for benzoylecgonine).

4 

Methylenedioxymethamphetamine (MDMA).

5 

Methylenedioxyamphetamine (MDA).

    157.7(2) Reserved.
