Prostatic Specific Antigen, Total (PSA)
Test Name Prostatic Specific Antigen, Total (PSA)
Specimen Type / Requirements Container Type = Serum Minimum Testing Volume = 1mL Serum Tube must fill to at least ½ or greater of its vacuum capacity
Specimen Handling Collection Instructions: Serum is the recommended sample. Serum collected with or without gel separator. Plasma samples should not be used. Ensure both samples and requisitions are lebeled properly. Write your initials, date and time of collection on the collection label. Laboratory Staff Instructions: Separate plasma as soon as possible. Turbid serum samples or samples containing particulate matter should be centrifuged prior to assay. Repeated freeze-thaw cycles have no effect on free PSA, total PSA, or % free PSA. Transportation: Transport at room temperature ASAP. Place on ice if time of collection to time sample get to lab exceeds 2hrs Stability: PSA is stable at room temperature for 24 hours, refrigerated for 5 days and frozen at -20 C for 5 months. Specimens to be held for longer than 5 months should be frozen at -70C. Sample Rejection Criteria: Plasma, unlabeled or Not Sufficient Quantity Samples will be rejected
