This test is not the same as Acid Phosphatase.
Values obtained with different assays should not be used interchangeably in serial testing. It is recommended that only one assay method be used consistently to monitor each patient's course of therapy. This procedure does not provide serial monitoring; it is intended for one-time use only. If serial monitoring is required, please use the serial monitoring number 480152.
2 - 3 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
0.2 mL (Note: This volume does not allow for repeat testing.)
Red-top tube or gel-barrier tube; do not use acid phosphatase transport tube.
If a red-top tube is used, transfer separated serum to a plastic transport tube. Specimen should be free of hemolysis and lipemia.
An adjunct in the evaluation of possible prostatic malignancy and useful in monitoring therapeutic progress
Immunochemiluminometric assay (ICMA)
Prostatic acid phosphatase has been used as a tumor marker ever since the observation by Gutman in 19381 that elevated levels of this enzyme are found in patients with metastatic prostate cancer. PAP determination in conjunction with PSA measurements is useful in assessing the prognosis of prostate cancer.2 Measurement of two markers allows identification of prostate cancer patients who have an elevation of PAP but not of PSA, and thus help monitoring the course of disease and response to treatment. PAP is more specific than PSA and less false-positives are seen due to benign prostatic hyperplasia.
