Drug Detection Panel by High-Resolution Time-of-Flight Mass Spectrometry, Serum or Plasma
Ordering Recommendation
Qualitative Liquid Chromatography-Time of Flight Mass Spectrometry
1-4 days
New York DOH Approval Status
This test is New York DOH approved.
Specimen Required
Patient Preparation
Gray (sodium fluoride/potassium oxalate). Also acceptable: Plain red, green (sodium heparin), lavender (EDTA), or pink (K2EDTA).  
Specimen Preparation
Remove plasma from cells ASAP or within 2 hours of collection. Transfer 4 mL plasma to an ARUP Standard Transport Tube. (Min: 2 mL) Also acceptable: Serum.  
Storage/Transport Temperature
Unacceptable Conditions
Specimens exposed to repeated freeze/thaw cycles. Separator tubes. Plasma or whole blood collected in lt. blue (sodium citrate).  
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  
Reference Interval
Interpretive Data
Methodology: Qualitative Liquid Chromatography-Time-of-Flight Mass Spectrometry

The absence of expected drug(s) and/or drug metabolite(s) may indicate non-compliance, inappropriate timing of specimen collection relative to drug administration, poor drug absorption, or limitations of testing. The concentration must be greater than or equal to the cutoff to be reported as present. If specific drug concentrations are required, contact the laboratory within two weeks of specimen collection to request confirmation and quantification by a second analytical technique.

For medical purposes only; not valid for forensic use.

Drugs covered and range of cutoff concentrations. Note that some drugs are identified based on the presence of unique drug metabolites not listed below.
