Test Code PSAD 
Test PROSTATE-SPECIFIC ANTIGEN (PSA), DIAGNOSTIC, SERUM 
Methodology Electrochemiluminescence Immunoassay 
Description Useful for aiding in the detection of early-stage prostate cancer in conjunction with digital rectal examination (DRE), and for indicating tumor recurrance and response to therapy for patients with a history of prostate cancer.

NOTE: This test, when ordered on Medicare patients, is subject to the National Coverage Determination (NCD) policy "Prostate Specific Antigen (Diagnostic)". Please verify that the diagnosis code (ICD-9) you have chosen demonstrates medical necessity for the test as documented in the physician's patient record. The CMS web site or the NorDx Limited Coverage Documentation Guide are available to assist you with this verification. A properly executed Advance Beneficiary Notice (ABN) must be submitted with the specimen if medical necessity is not demonstrated by the ICD-9 code chosen. 

Specimen Draw blood in either a plain, red-top or serum gel tube. Spin down and send 1.0 mL (minimum volume: 0.5 mL) of serum refrigerated. PSA specimens should be drawn prior to prostatic manipulations such as DRE, prostatic massage, transrectal ultrasound (TRUS), and prostatic biopsy. These procedures may falsely elevate PSA valuesl.

NOTE: No sample should be collected on patients receiving therapy with high biotin doses (i.e. > 5 mg/day) until at least 8 hours after the last biotin administration.
