Test ID: FFTOL
Toluene, Occupational Exposure, Serum
Specimen Type 
Describes the specimen type needed for testing
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 1 of the following specimens:
Plasma
Draw blood in a green-top (sodium heparin) tube(s). (Plasma gel
tube is not acceptable.) Spin tubes immediately and fill 2
transfer tubes completely to prevent loss of volatile compound into
headspace. Send 20 mL sodium heparin plasma refrigerated.
Note: 1. Indicate plasma on request form.
2. Label specimen appropriately (plasma).
Serum
Draw blood in a plain, red-top tube(s). (Serum gel tube is not
acceptable.) Spin tubes immediately and fill 2 transfer tubes
completely to prevent loss of volatile compound into headspace.
Send 20 mL of serum refrigerated.
Note: 1. Indicate serum on request form.
2. Label specimen appropriately (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.
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
