A Mission
in Health You Can Trust
It was recently brought to our
attention that men are interested in variations in PSA values that
are obtained from different machines. If the equipment in your doctor's
office is different from the equipment at the lab your specimen
is sent to you may receive results that fluctuate 1 point or more!
Here is the data from the New York State Tumor Marker Proficiency
Test conducted in January 2005:
