Dear John and DaveBaxt
Sound advice John although I can understand your being worried DaveBaxt when your reading was taken after just 4 weeks.
My first PSA was 6 weeks post op. Reading was given as 0.02. I am pleased to read in thread here that a reading of <0.1 is regarded as undetectable so even more pleased.
My urologist has called for next PSA in 4 months.
Best wishes. Let us know how you get your reading.
Cheers
Grant
