(a) As a laboratory, you must use the cutoff concentrations displayed in the following table for initial and confirmatory drug tests. All cutoff concentrations are expressed in nanograms per milliliter (ng/mL). The table follows:
| Initial test analyte | Initial test cutoff concentration | Confirmatory test analyte | Confirmatory test cutoff concentration |
|---|---|---|---|
| Marijuana metabolites | 50 ng/mL | THCA 1 | 15 ng/mL. |
| Cocaine metabolites | 150 ng/mL | Benzoylecgonine | 100 ng/mL. |
| Opiate metabolites | |||
| Codeine/Morphine 2 | 2000 ng/mL | Codeine | 2000 ng/mL. |
| Morphine | 2000 ng/mL. | ||
| 6-Acetylmorphine | 10 ng/mL | 6-Acetylmorphine | 10 ng/mL. |
| Phencyclidine | 25 ng/mL | Phencyclidine | 25 ng/mL. |
| Amphetamines 3 | |||
| AMP/MAMP 4 | 500 ng/mL | Amphetamine | 250 ng/mL. |
| Methamphetamine 5 | 250 ng/mL. | ||
| MDMA 6 | 500 ng/mL | MDMA | 250 ng/mL. |
| MDA 7 | 250 ng/mL. | ||
| MDEA 8 | 250 ng/mL |
1 Delta-9-tetrahydrocannabinol-9-carboxylic acid (THCA).
2 Morphine is the target analyte for codeine/morphine testing.
3 Either a single initial test kit or multiple initial test kits may be used provided the single test kit detects each target analyte independently at the specified cutoff.
4 Methamphetamine is the target analyte for amphetamine/methamphetamine testing.
5 To be reported positive for methamphetamine, a specimen must also contain amphetamine at a concentration equal to or greater than 100 ng/mL.
6 Methylenedioxymethamphetamine (MDMA).
7 Methylenedioxyamphetamine (MDA).
8 Methylenedioxyethylamphetamine (MDEA).
(b) On an initial drug test, you must report a result below the cutoff concentration as negative. If the result is at or above the cutoff concentration, you must conduct a confirmation test.
(c) On a confirmation drug test, you must report a result below the cutoff concentration as negative and a result at or above the cutoff concentration as confirmed positive.
(d) You must report quantitative values for morphine or codeine at 15,000 ng/mL or above.
