O.1 means one part in ten, 0.10 means 10 parts in 100 and 0.100 means 100 parts in 1000. Its all the same thing. So, if someone got a PSA score of 0.12 This is 12 parts in 100 or 12/100's. If this same result was reported with three decimal places it would be 0.120 The third value after the decimal is much less significant than the second value It yields the PSA score to one decimal point. For example, my pre-surgery PSA reading was 4.4. After surgery, I was switched to the ultra-sensitive PSA test at Quest Diagnostics which yields a PSA reading to two decimal places. My first reading, post-surgery was less than or equal to 0.10. In order to detect ultra-low concentrations of the cancer biomarker PSA, we utilized SiMoA, a recently developed ultra-sensitive ELISA based on single molecule counting technology 9. The test is very sensitive and can pick up small changes in PSA levels. Doctors will usually want to know how quickly levels of PSA in the blood are rising. To find this out, a person will need to Ok, my lab was doing the <.01 sensitivity and I get it done monthly. As of Oct. - lab started to go down to .xxx . Oct and Nov --- .006 Dec test comes back and is <.015 PSA is a type of protein that's made by both normal cells in the prostate gland and cancer cells. It can be found in your blood and semen, and its measurement is often used to check for new or The difference between 0.05 and 0.07 is well with the standard deviation of the sensitive PSA testing criteria. My oncologist does not use the ultra sensitive PSA test and I get tested every 90 days. But I would also be religious about verifying PSA scores on a very regular basis and if that began to change I would seriously consider When my urologist saw my PSA come back at .3 she referred my to a radiologist who apparently didn't care for the regular PSA test and not I o only take the ultra sensitive PSA test. It is a Roche Post Protatectomy ultra sensitive PSA test. Reply (1) Report. VLBIV in reply to Takenca 8 months ago. Thank you. If my next PSA result is low, I I always get an ultra sensitive test--to two decimal places. Due to the uro's office staff checking the wrong box on the lab form, Quest did only a standard test to just one decimal place. They reported the result as 0.1 without a <. My uro had them retest with the ultra sensitive test I was meant to have and the result came back as 0.05. To form the complex between the liposomes and anti-PSA monoclonal antibody-immobilized wells (used as purchased 12 strips × 8 wells) in the presence of PSA, 100 μL of PSA solution was first ki72OGS.
