Why a Hybritech PSA and free PSA Test?
The Hybritech PSA and free PSA tests are widely regarded as among the most trusted tests for prostate cancer detection. Indeed, the commonly used cutoffs and other criteria for evaluating PSA and free PSA results by other PSA test manufacturers are based on the performance of the original Hybritech tests. Because PSA tests are not all standardized, these cutoffs and criteria do not necessarily apply to other manufacturers’ assays. The original research that led the FDA to declare the PSA test as a safe and effective method for detecting prostate cancer was performed using the Hybritech Tandem-R PSA test because of its desirable characteristics. The Hybritech Tandem-R free PSA test was used in the research that established the usefulness of free PSA. If a patient’s PSA test was performed with a Hybritech test, it is also important that his free PSA be measured with the Hybritech free PSA test, because PSA and free PSA results must be calibrated to each other.
