Test ID: FDS9R    
Drug Screen 9 Panel, Serum or Plasma-Immunoassay Screen with Reflex to Mass Spectrometry Confirmation/Quantitation

Specimen Type Describes the specimen type needed for testing

Varies

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Submit only one of the following:

 

Plasma

Draw blood in a gray top potassium oxalate/sodium fluoride, green (sodium heparin), lavender (EDTA), or pink (K2EDTA) tube(s). Spin down and send 4 mL of plasma refrigerate in a plastic vial.

 

Serum

Draw blood in a plain, red-top tube(s). Spin down and send 4 mL of serum refrigerate in a plastic vial.

 

Note: Cocaine and cocaethylene are more stable in fluoride-preserved plasma than serum.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

3 mL

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
