Hello everyone. My husband, Andy, had a Retzius sparing RARP on 9.6.25 and has just received the result of his first post-op PSA test. It has come back as <0.03. I know this is a good result, but I have today read online that it isn't considered undetectable until it reaches 0.01 and I'm now a bit worried and don't know if I should be.

Do not worry. The only important bit is the < (less than) symbol. This means it is undetectable on the testing machine that they use. Some hospitals use different testing machines, so you may see other values quoted as undetectable, but in reality the < symbol is what is important.

Once you get below 0.1 the test machines have random errors so a lot of hospitals now consider <0.1 as undetectable.

Zoogirl, good to hear things are going ok, if your tests are being done at city you will never get a 0.01 result, they only test down to 0.025, and I don't think all the machines are capable of testing down to that level. 

There is a support meeting on Thursday at the university. I Will attach the details, I think the speaker this week is talking about why the NHS is broken.

Thanks Chris

Hi Zoogirl.

It's a fantastic undetectable result for Andy. Long may they continue.👍

As Dave says its the < arrow that matters, it means it's the lowest that particular lab measures down to.

I've had post op PSA tests at two labs. One measures down to 0.04 and the other to 0.02. My reading from the first was <0.04, my readings from the second were all <0.02. All undetectable, and I'm now over two and a half years post-op.

Best of luck to you both.👍

It's a good result. The sensitivity of these tests seem to vary depending who the provider is mine, only goes down to <0.04. 

Following my RP I was expecting my reading to be 0. If it wasn't for this forum I would not have realised '<' (less than) is the key component in the reading.
