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 Member
I just received results with PSA at

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 first ultrasentive test was the Post Prostatectomy PSA with HAMA Treatment (eliminates interference from human anti-mouse antibodies (HAMA) that may be present in patients who have received mouse monoclonal antibody preparations) and, later my family doctor did a Post Prostatectomy PSA ultra-sensitive. Since this last ultra-sensitive test
The ZERO - The End of Prostate Cancer Support Community connects patients, families, friends and caregivers to enhance the quality of life for all those affected by prostate cancer.

It is currently detected using a blood test that measures PSA levels. Although it provides early diagnosis, the PSA blood test has a low specificity (high false positives) with about 75 per cent

My urologist threshold was PSA=0.06 in RP success judgement but some use a threshold of 0.03. However, both numbers indicate remission. As far as I am aware of, the two decimal places (0.XX) ultra sensitive assays, independently of the maker (Abott, Boehringer,Cobas, etc), got tolerances in the LLD of (0.01, 0.02 and 0.05). LLD of

The optimal cut-off values for detecting prostate cancer were defined as 4.92 ng/mL in PSA2 (sensitivity, 65.4%; specificity, 56.5%; area under curve (AUC), 0.64; P=0.002), 0.155 ng/mL/g in PSAD (sensitivity, 73.1%; specificity, 71.2%; AUC, 0.762; P Specifically, some institutions use the ultra sensitive PSA that measures down to .015. Others use the regular PSA that goes to 0.1. Some say the ultra sensitive test detects a possible recurrence at an earlier time.

Just had my 9 month PSA test and it is still undetectable. There are other things to consider like tumor volume, pre surgery PSA and Gleason score. The waiting is the worst. Also, be aware that even if the first test does show some detectable PSA that it might mean that some prostate tissue was left behind and is still producing PSA.

Once again, a cutoff of 0.03 ng/ml on a first ultrasensitive PSA test seems to be an excellent indicator of eventual traditional biochemical recurrence (0.2 ng/ml). In other words, if the PSA reaches 0.03, it will most likely (77% of the time) reach 0.2. Treating before PSA reaches 0.2 offers good lead time advantage, increasing the probability
In the late 1980s and early 1990s, the prostate specific antigen (PSA) test, which measures a protein produced by both normal and cancerous cells in the prostate, emerged as a simple blood test to indicate the likelihood of having prostate cancer. Millions of men over the age of 50 in the U.S. who were free of signs and symptoms of the disease

Prostate-specific antigen (PSA) is a protein that forms in the prostate gland. A PSA test calculates PSA levels in the blood. While it cannot stage cancer by itself, it is a useful screening tool
