Special Info
Specimens which are hemolyzed, exposed to repeated freeze/thaw cycles, or collected in gel separator tubes will be rejected. This test is New York DOH approved.
Clinical Info
This test is useful to monitor patient compliance. This test does not distinguish between the delta-8 and delta-9 forms of THC or their metabolites. Drugs/Drug classes reported as "Positive" are automatically reflexed to mass spectrometry confirmation/quantitation testing. An immunoassay unconfirmed positive screen result may be useful for medical purposes but does not meet forensic standards. The absence of expected drug(s) and/or drug metabolite(s) may indicate noncompliance, inappropriate timing of specimen collection relative to drug administration, poor drug absorption, or limitations of testing. The concentration at which the screening test can detect a drug or metabolite varies within a drug class. Specimens for which drugs or drug classes are detected by the screen are automatically reflexed to a second, more specific technology (mass spectrometry) at additional cost. The concentration value must be greater than or equal to the cutoff to be reported as positive.
Clinical Limitation
This is a blood drug screen. In most situations, urine drug screening is recommended due to the longer window of detection, faster turnaround time, and ability to test without invasive sampling. If your patient is not anuric or oliguric, please consider ordering Toxicology Screen, Urine (UTOX2) or an appropriate confirmation test. This test is for medical purposes only; not valid for forensic use. Cocaine and cocaethylene are more stable in fluoride-preserved plasma than serum.
