I had a PSA test at Quest Diagnostics in Mpls area yesterday. My PSA was 5.1. My December PSA at Mayo was 6.2. Quest has an explanation attached that they use the WHO system which is 20% lower than the Beckman Coulter system. Its important to know which system your baseline came from. I'm not sure What Mayo uses, AI says they use the Beckman. I haven't seen this mentioned anywhere . One more question to add to your lists.

This is a reason why they tell people to go to the same place to get their blood test every time. PSA results don’t always agree between Labs, Looks like you may have found one reason. I don’t think most people have any idea what technology is used for their blood test.
Interesting information.
