Why then measure lower values? With the ultra sensitive PSA test, normally fluctuations will occur. How will you deal with 0.01 at one test and three months later 0.04? You probably becomes anxious! Unnecessarily. With your pathology - avoid PSA stress and anxiety by continuing with the regular test. PSA at .01 and .02ng are still very low and as noted waiting for another test is the best thing to do, anxiety associated with the waiting and anticipation aside! IMO, Do NOT look for an ultra-sensitive PSA test as it provides no useful diagnostics and only adds to the anxiety when you see that third digit move around. PSA density: This number compares the amount of PSA to the size of the prostate on MRI or ultrasound, as cancers usually make more PSA per volume of tissue than normal prostate cells. This test is somewhat limited as a prostate ultrasound or MRI are needed to make the comparison. My surgeon uses the ultra sensitive PSA, but I had him put a note on my chart to just tell me "undetectable" or not. Regular Member. Joined : Nov 2012. Posts : 31. Posted 12/16/2013 2:20 PM (GMT -8) I have had three psa tests since my operation. The first two were >.002. Now I have a .2 psa. If you have an abnormal PSA score, your doctor may recommend another newer test that gives a better sense of your prostate cancer risk . The prostate health index (PHI) is one such test that is a more accurate blood test and measures your risk for having prostate cancer. Firstly ultra-sensitive PSA tests ie. to two decimal places or more, do vary so .07 to .08 may not be truly significant. DHT is dihydrotestosterone, a kind of super-charged testosterone that usually runs about 10% of regular testosterone and is thought to be a major fuel to PCa cells. So if a man's normal T = 700, DHT is expected to be 70 vppm.
