That _is_ an "ultra-sensitive" test; the regular PSA test would give "
Assays that measure PSA to concentrations below 0.1 ng/mL are denoted ultrasensitive PSA (USPSA). The use of USPSA cutpoints below currently recommended PSA thresholds may be helpful in identifying cases of early biochemical recurrence and for selecting patients with adverse clinicopathologic risk factors for secondary therapy.

Hi All, Five months ago I posted that I went from an ultra sensitive psa of The ultrasensitive test is used for post-treatment monitoring of patients who are at the extreme low end, when we are looking for small changes from (say) 0.02 to 0.05. For patients like your father who is in the hundreds, the 'standard' test is fine. Pabz01 Regular MemberIf a test can measure only to 0.1, and the level measured is somewhere below that (0.00 - 0.099), it will come back to you as < 0.1 (Less Than 0.1). That is undetectable according to the test. There are others that are good down to 0.03, so again, 0.00-0.029, if it were there, would be undetectable.
1) I'm suspicious that you got a standard vs ultra sensitive PSA post surgery. The lower limit of a standard PSA is .1. 2) First PSA at 6 weeks is a little early. Sometimes their is residual tissue left over from the surgery. My PSA has been hovering around 0.241 since my robotic surgery.
The regular test's lowest reading is < 0.1 not < 0.02. Each lab can have a different cutoff. Some may have a < 0.01 cutoff. Based on the fact PSA can fluctuate 0.01-0.02 and having nothing to do with Prostate Cancer, I would prefer to not see results beyond two decimals, especially while under 0.02. 1 Reactions.
CONCLUSIONS: Agreement between prostate specific antigen doubling time calculated using ultrasensitive vs traditional prostate specific antigen values is poor. Ultrasensitive prostate specific antigen doubling time is often significantly more rapid than traditional prostate specific antigen doubling time, potentially overestimating the risk of
Is there an advantage to getting the ultrasensitive PSA instead of the total PSA? Knowing just that the result is less than 0.1 seems a bit like a dummy light on a car that goes on only when things really need attention. Maybe its better to know what, if anything, is happening at a lower level than 0.1?oBMaOr5.
