Prostatic Acid Phosphatase : 0070120

Mnemonic: PAP

Methodology: Chemiluminescent Immunoassay
Performed: Sun-Sat
Reported: Within 24 hours
Specimen Required: Patient Prep:  Specimen should be obtained before rectal examination, biopsy, prostatectomy or prostatic massage, since manipulation of the prostrate gland may lead to elevated PAP levels persisting up to 24-48 hours.

Collect:  One 4 mL serum separator tube.

Storage/Transport Temperature:  1 mL serum, frozen. (Min: 0.5 mL) Submit specimen in an ARUP Standard Transport Tube.

Remarks:  Separate specimens must be submitted when multiple tests are ordered.  Allow specimen to clot completely at room temperature before centrifuging.

Unacceptable Conditions:  Specimens ambient greater than 3 hours or refrigerated greater than 24 hours.

Stability (collection to initiation of testing):  After separation from cells: Ambient: 3 hours; Refrigerated: 24 hours; Frozen: 6 months
Reference Interval:
0.0-3.5 ng/mL
Interpretive Data: The Siemens Immulite® 2000 PAP chemiluminescent immunoassay method is used.  Results obtained with different assay methods or kits cannot be used interchangeably.  Measurement of PAP has been shown to be clinically relevant in the management of patients with prostatic adenocarcinoma.  Benign prostatic hyperplasia, prostate massage, and prostatic infarction may result in elevated PAP concentrations.  The PAP assay value, regardless of level, should not be interpreted as evidence for the presence or absence of malignant disease.
CPT Code(s): 84066
Cross References: Acid Phosphatase, Prostatic, PAP
