The HHScertified laboratory shall apply the confirmatory cutoff levels specified in this paragraph, except as permitted in paragraph (a)(2) of this section or the licensee or other entity has established more stringent cutoff levels. (1) A specimen that is identified as positive on an initial drug test must be subject to confirmatory testing for the class(es) of drugs for which the specimen initially tested positive. (iii) The laboratory shall report the numerical values obtained from this special analysis to the MRO. (ii) If any immunoassay response is equal to or greater than 40 percent of the cutoff calibrator, the laboratory shall conduct confirmatory drug testing of the specimen to the LOQ for those drugs and/or drug metabolites and (i) If initial validity testing indicates that a specimen is dilute, or if a specimen is collected under direct observation for any of the conditions specified in § 26.115(a)(1) through (3) or (a)(5), the laboratory shall compare the immunoassay responses of the specimen to the cutoff calibrator in each drug class tested (2) HHS-certified laboratories shall conduct special analyses of specimens as follows: Or greater than the initial test cutoff or, alternatively,Ģ An immunoassay must be calibrated with the target analyte, delta-9-tetrahydrocannabinol (THC).ģ Alternate technology (THC and 6–AM): The confirmatory tests cutoff must be used for an alternate technology initial test that is specific for the target analyte ( i.e., 2 ng/mL for THC, 2 ng/mL for 6–AM).Ĥ Amphetamine (AMP) and methamphetamine (MAMP).ĥ Methylenedioxymethamphetamine (MDMA) and methylenedioxyamphetamine (MDA). Within the group must have a concentration equal to ![]() Alternative technology: Either one analyte or allĪnalytes from the group must be used for calibration,ĭepending on the technology.Or greater if not, separate immunoassays mustīe used for the analytes within the group. The other analyte(s) within the group must be 80 percent The cross reactivity of the immunoassay to One analyte from the group identified as the targetĪnalyte. ![]()
