Test Name: Sunquest Test Code Epic Procedure Code Or ID CPT Code:  

PROSTATIC ACID PHOS

ORDERING INFORMATION:
Sunquest Test Code:
PAP      Geisinger Epic Procedure Code: 84066.02         Geisinger Epic ID: 17214

SPECIMEN COLLECTION
Specimen type:
Serum
Preferred collection container:
Alternate Collection Container:
6 mL red-top (plain, non-serum separator) tube
Specimen required:
1 mL aliquot of serum; minimum 0.5 mL. Please submit a separate frozen aliquot for this test. It may not be combined with any other test requiring a frozen aliquot.
Special notes:
Samples should be obtained before rectal examination, biopsy, prostatectomy, or prostatic massage, since manipulating the prostate gland may lead to elevated PAP levels persisting up to 24-48 hours.

Test includes:
Prostatic acid phosphatase.
Methodology:
Immunoassay
Synonyms:
ACID PHOS, PROSTATIC
Quest test code 208
Clinical significance:
High concentrations of acid phosphatase are found in the prostate gland. Significant amounts are also found in platelets, bone, spleen, kidney and liver. Prostatic Acid Phosphatase (PAP) is a component of total acid phosphates and is a major constituent in seminal fluid and is also secreted in the urine. PAP is normally found in serum in very low levels. PAP measurement has found clinical application in the management of prostatic cancer patients. Serum PAP measurements have been useful in monitoring remission or relapse of a prostatic malignancy and in assessing the effectiveness of various treatment regimes. Thus, normalization in serum PAP levels has been observed following successful therapeutic intervention, while recurrent or residual disease has been associated with elevated levels of PAP.
