Gaskets and pads with PSA backing are often called "peel and stick". Other common terms are pressure sensitive tapes and double sided tapes. Supported or Double Coated Adhesive - This type of PSA is made by coating each side of a thin carrier commonly P.E.T. film with layer of adhesive. When applied to an elastomer, the carrier gives the Prostate-specific antigen (PSA) synthesis is related to testosterone, which has a diurnal rhythm. PSA might have a diurnal variation and the timing of measurement could change the clinical practice for prostate biopsy. Male patients complaining of lower urinary tract symptoms (group 1) and diagnosed with prostate cancer (group 2) were recruited First psa after prostactomy should be after about 45 days. If undetectable and favourable pathology report go for three monthly. If unfavorable path report and/or psa detected, go for monthly. Any three consecutive rise above 0.03 means recurrence and go for salvage radiation plus a few months of ADT for best results. The tests are done with my husband going at 7am to one collection centre and then at 7:30 to the next on the same day. Both are ultrasensitive tests - Lab 1 (Prince Alfred) uses the Immulite 2000 3rd gen whereas Lab 2 (Douglas Hanly Moir) uses Abbott Architect. Both tests are I believe calibrated to the WHO standard. 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. Your PSA is Undetectable. Ed Weber, M.D., Editor January- February, 2015. The Measurement: It used to be simple. An undetectable PSA pf 0.1 ng/mL 4 - 6 weeks after surgery carried an encouraging bit of reassurance of a clean removal and a good prognosis.. But … no more! The more sensitive the assay, the shorter the period of this reassurance. Many conditions can cause an elevated PSA. Though there is always some risk of the PSA test resulting in a "false negative" (a normal PSA reading when cancer is present), an increase in PSA levels may result from: A prostate gland biopsy; A resection of the prostate; Rigorous physical activity related to the prostate (i.e. bicycle riding) 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 A new study suggests that the ultrasensitive PSA test may help clinicians advise patients post-prostatectomy on whether or not to get adjuvant radiation therapy, says Dr Gerald Chodak. 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. JTcgLOK.
