Diagnostic Testing Medical

Test name: Progesterone

Order Code: PROG

Preferred Specimen: 2mL serum in a Serum Separator Tube (SST or Tiger-top)

CPT Code: 84144

Collection: Allow SST to clot in an upright position for 30 min, then centrifuge sample within 2 hours of collection. Refrigerate.

Special Instructions and Considerations: Samples should not be taken from patients receiving therapy with high biotin doses (i.e. > 5 mg/day) until at least 8 hours following the last biotin administration. Phenylbutazone at therapeutic dosage levels showed interference with the assay (progesterone values depressed).

Transport Temperature: Refrigerated

Specimen Stability: 1 day under room temperature; 5 days refrigerated
