Amounts such as on-call, cash bonuses, and nursing weekend and unanticipated-needs premiums are types of non-discretionary payments that are included in the calculation of overtime if paid at the time-and-one-half rate.
A prostate-specific antigen (PSA) test measures the level of PSA in the blood. The prostate gland produces PSA, a protein that at an elevated level may be a sign of prostate cancer.
Free PSA Test Helps in Prostate Cancer Diagnosis by William J. Catalona, M.D. A relatively new and helpful addition in the diagnosis of prostate cancer is the free PSA Test. This blood test is done in addition to the PSA Test and the finger (digital) examination. The PSA Test measures a protein in the blood that is produced only by the prostate gland. Some of the PSA in blood is bound to other proteins and the rest circulates freely. This free PSA is a damaged variant of PSA that no longer is able to bind to other proteins and thus circulates in the blood in the unbound (free) form.
