Desyrel, Trazodone, Antrim #17061, EPIC: LAB5427, SOFT: TRAZO
Specimen Collection Criteria
Collect: One plain Red-top tube. (Minimum Whole Blood: 2.0 mL)
Do not use Serum Separator Tubes.
Time of Collection: Trough, just prior to the next dose.
Record the exact time of specimen collection on the tube or in the computer system.
Physician Office/Drawsite Specimen Preparation
Let specimens clot 30-60 minutes. Centrifuge specimen to separate serum from cells. Refrigerate (2-8°C or 36-46°F) the centrifuged collection tube within two hours of collection. (Min: 0.5 mL serum)
Preparation for Courier Transport
Transport: Centrifuged collection tube, refrigerated (2-8°C or 36-46°F). (Min: 0.5 mL serum)
- Serum Separator (SST) tubes.
- Severely lipemic or hemolyzed specimens.

Critical Value: Greater than 5.0 mcg/mL.
Liquid Chromatography/Tandem Mass Spectrometry (LC/MS/MS)
This test was developed and its performance characteristics determined by Beaumont Health. It has not been cleared or approved by the FDA. The Laboratory is regulated under CLIA as qualified to perform high-complexity testing. This test is used for clinical purposes and should not be regarded as investigational or for research.
This assay measures Trazodone concentrations in serum. Trazodone is metabolized to an active metabolite, m-chlorophenylpiperazine (m-CPP), which is not measured. Trazodone concentrations have been shown to average ten times that of m-CPP.
Trazodone is indicated for the treatment of depression. This assay is used for the therapeutic monitoring and toxicity assessment of trazodone.
