Thanks for the words of encouragement - it really, really helps. It is especially helpful to see the PSA numbers of others.
I have posted on this before, but I may again consider searching out a urologist who uses the "conventional" PSA test with a sensitivity threshold of 0.1. While attempting to switch assays earlier, I personally found a general lack of knowledge surrounding PSA tests and statistics in the medical community. I guess the type of information that I and some others are looking for comes from research scientists/doctors and statisticians, more so than the urologist/GP/nurse who is on the "front line", at least in my opinion. As others have experienced, I have had PSA numbers reported to me incorrectly on two occasions, as if there is not enough anxiety and uncertainty already. This time, I may first at least wait until I (hopefully) see a plateau or reduction in an ultrasensitive test result, and then switch doctors to go for the "conventional" test.
Does anyone know of a urologist in Silicon Valley that uses the "conventional" PSA test?
