Sec.  40.87  What are the cutoff concentrations for initial and confirmation tests?

     (a) As a laboratory, you must use the cutoff concentrations displayed in the following table for initial and confirmation drug tests. All cutoff concentrations are expressed in nanograms 

[[Page 615]] 

per milliliter (ng/mL). The table follows: 

------------------------------------------------------------------------

                                     Initial

    Type of drug or metabolite         test         Confirmation test

------------------------------------------------------------------------

(1) Marijuana metabolites........           50  ........................

(i) Delta-9-tetrahydrocanna-binol-              15

 9-carboxylic acid (THC).

(2) Cocaine metabolites                    300  150

 (Benzoylecgonine).

(3) Phencyclidine (PCP)..........           25  25

(4) Amphetamines.................         1000  ........................

(i) Amphetamine..................  ...........  500

(ii) Methamphetamine.............  ...........  500 (Specimen must also

                                                 contain amphetamine at

                                                 a concentration of

                                                 greater than or equal

                                                 to 200 ng/mL.)

(5) Opiate metabolites...........         2000  ........................

(i) Codeine......................  ...........  2000

(ii) Morphine....................  ...........  2000

(iii) 6-acetylmorphine (6-AM)....  ...........  10 (Test for 6-AM in the

                                                 specimen. Conduct this

                                                 test only when specimen

                                                 contains morphine at a

                                                 concentration greater

                                                 than or equal to 2000

                                                 ng/mL.)

------------------------------------------------------------------------

 

    (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.
