It has been my experience that many GPs have less knowledge of the intricacies of PCa and the related testing than many of the members here on Healingwell. And no wonder, in the normal course of events they really do not need to. All their day to day orders for a PSA test would involve results that would be "normal" or "abnormal" (ie high, requiring referral to a specialist). I have not seen a urologist for many years, but rather have had my GP request the PSA. But I constantly remind him to word the order as "Ultrasensitve PSA (post prostatectomy)". And I always ensure I get a hard copy of the result.
Sadly, many receptionists are indifferent or even callous when dealing with patients and react with anger when what they say is queried.
Very often the PSA result, even when tested with an Ultrasensitive assay, is rounded up to 1 decimal place. ie an undetectable result on very low sensitivity equipment will simply be reported as <.1 (with 0.4 to 4 being the expected normal intact prostate test result).
In the early days of my testing (2008/9) the lab my then GP used had the Siemens Immulite 2000 which had a lower sensitivity detection level of .003. My results have always been undetectable but they constantly reported <.1. It took quite a bit of me jumping up and down (via the GP) before they started giving the actual ultrasensitve result.
