UCMC Collection Instructions
1. Collect sample following standard collection methods
2. Within 2 hours of collection the sample must be received in
Laboratory Service Center
3. Transport room temperature (15 – 25˚C)
Test Usage
Use for screening when no disease or symptoms indicated.
Indicated for the measurement of total PSA in conjunction with
digital rectal examination (DRE) as an
aid in the detection of
prostate cancer in men aged 50 years or older. Prostate biopsy
is
required for diagnosis of prostate cancer. The test is further
indicated for serial measurement of PSA
to aid in the management of
cancer patients.

Test Limitations
The measured PSA value of a
patient���s sample can vary
depending on the testing procedure used. PSA values determined
on
patient samples by different testing procedures cannot be
directly
compared with one another and could be the cause of erroneous
medical interpretations. An inflammation or trauma of the
prostate
(e.g. in cases of urinary retention or following rectal
examination, cystoscopy, coloscopy, transurethral biopsy, laser
treatment or ergometry) can lead to PSA
elevations of varying
duration and magnitude. It is known that in rare cases PSA isoforms
do exist which may be measured differently by different
PSA tests.
Findings of this kind have occasionally been reported for
PSA tests
from various manufacturers.
