As a result, they are imperfect surrogate measures of the activity of prostate cancer. However, they are the best practical messures currently available. As such, any particular PSA test result can be thought to represent the " value/ severity" of the prostate cancer at the time that measurement was taken. Herein, we report ultra-sensitive sensing of a prostate-specific antigen (PSA), which is used as a biomarker to detect prostate cancer, using a molybdenum series (MoO 3, MoS 2, and MoSe 2) of two-dimensional nanosheets (2D NSs).Moreover, the design of a 2D NS-based PSA aptamer sensor system was demonstrated based on a fluorescence turn-on mechanism in the presence of a target. Posted 8/22/2010 6:47 AM (GMT -8) I agree with the value of the ultra sensitive PSA. My PSA went from .07 to .28 within 3 months and them to .5 two months later. If I had been using the normal test, I wuld have not been able to plan for secondary treatment until my PSA was almost .3 and movng very quickly. Purgatory. Interpretive Data. After radical prostatectomy, the reference interval is less than 0.05 ng/mL if there is no residual disease. In healthy individuals without prostatectomy, the reference interval is 4.00 ng/mL or less. Lower limit of detection is 0.01 ng/mL. The Roche PSA electrochemiluminescent immunoassay is used. 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 In patients with metastatic hormone-sensitive prostate cancer (mHSPC) undergoing intensified androgen deprivation therapy (ADT), not achieving an optimal PSA response, defined as PSA nadir >0.2 ng Regular Member.
