It is mostly curiosity about the difference between my ultra sensitive and regular psa tests results. The ultra has always been 3 decimal points and the regular 2 decimal points. All of the blood draws were at the same place and the tests sent to the same lab. As I said before, in 2016 I had one blood draw that gave two different results. ( rechecked for accuracy) ultra was .178 and the regular was .19. The ultra sensitive has always been lower. I get both results because different Docs ordered different tests. No one at the lab can explain the difference. It makes you wonder about the accuracy.
I'm with you there, lifeguyd. It's maddening (see my signature). That's why clear trends established over time matter so much more than any particular result.
Btw, now you can see, perhaps, why DWI defense lawyers (I was one, for a short while) pull their hair out when a judge or jury unquestioningly accepts a BAC result marginally over the .08 limit with slim assurance of its accuracy, and when state laws restrict defendants' access to equipment maintenance records etc.
