Test ID: FFTLB
Toluene, Occupational Exposure, Blood
Specimen Type 
Describes the specimen type needed for testing
WB Sodium Heparin
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.
Draw blood in 2 green top (sodium heparin) tubes.
Tubes should be filled to prevent loss of volatile compound into
headspace. Send 20 mL of sodium heparin whole blood refrigerated.
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.
2.5 mL NOTE: Submission of the minimum volume results in an elevated reporting limit and inability to repeat analysis.
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
