@scooter are you using a greater than or less than symbol? I'm testing this now < the less then symbol gave us issues before.

It doesn't seem to be the < or > symbol that is the issue. Are you using another special character? Please send me the text you wish to post using this form and I'll get it figured out.

Had a recurrence 2.5 years ago after prostatectomy. Radiation and 9 months of hormone therapy was the treatment. My latest PSA result was less than .1, the last three PSA test results were all less than .01.

Due to an insurance change I went to a new Doctor and a new lab performed the PSA test on 05/02/2023 which resulted in the less than .1 result. Could this be due to the new lab or should I be concerned.

I believe it was the less than symbol. Thanks.

Thats a good psa. You will get a bump in psa here and there.

It may be an apples to oranges comparison. If the new lab is saying less than .1, it may not be as sensitive a test as the previous lab was doing. Less than .1 could actually equal less than .01 if the tests aren't the same sensitivity.

I realize it's not always doable, but, I go to the same lab, same time and day of the week for as much consistency as possible.

First less than .1 is good. Different labs use different methods. My first 2 PSA tests reported values of less than 0.1. My last test was .03 but the reference range of the test was shown with my result. The range was .03 to 4.0. So my PSA was as low as the sensitivity of the test I took. So it is very possible the sensitivity of the test you just took was 0.1 like the first 2 tests I took after my RALP.

Thinking about it now, as I said I have a new doctor and they probably ordered a regular PSA test which I believe only detects to less than .1

Every other ultra sensitive test that I have had read to 2 decimal places which was giving me readings of less than .01

Will be confirming with the doctor when I see her this Thursday as to which test they ordered.

I believe you are right.

I agree with @web265 it is important to keep using the same lab. I would have thought measuring to .010 would be the standard. My lab measures to less than .008.
