Thank you for your question. 6 weeks from your operation should be the soonest you will be able to get a reliable reading of your post op PSA. It is likely your PSA will continue to fall as the PSA made by your prostate before it was removed is still in your circulation. you should visit with your doctor after the 6 weeks post operative PSA results are available.
