Drug Screen 9 Panel, Serum or Plasma - Immunoassay Screen with Reflex to Mass Spectrometry Confirmation/Quantitation
Ordering Recommendation
Use to monitor patient compliance. This test does not distinguish between the delta-8 and delta-9 forms of THC or their metabolites.
New York DOH Approval Status
Specimen Required
Gray (sodium fluoride/potassium oxalate). Also acceptable: Plain red, green (sodium heparin), lavender (EDTA), or pink (K2EDTA).
Remove plasma from cells ASAP or within 2 hours of collection. Transfer 4 mL plasma to an ARUP Standard Transport Tube. (Min: 3 mL) Also acceptable: Serum.
Refrigerated.
Specimens exposed to repeated freeze/thaw cycles. Separator tubes. Plasma or whole blood collected in lt. blue (sodium citrate). Hemolyzed specimens.
Cocaine and cocaethylene are more stable in fluoride-preserved plasma than serum.
After separation from cells: Ambient: 1 week; Refrigerated: 2 weeks; Frozen: 3 years

Interpretive Data
Drugs/Drug classes reported as "Positive" are automatically reflexed to mass spectrometry confirmation/quantitation. An unconfirmed positive immunoassay 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 (GC/MS and/or LC-MS/MS). The concentration value must be greater than or equal to the cutoff to be reported as positive. Interpretive questions should be directed to the laboratory.
For medical purposes only; not valid for forensic use.
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
Laboratory Developed Test (LDT)
Note
Screen-positive specimens are automatically confirmed by GC/MS and/or LC-MS/MS; additional charges may apply.
