2 Reliability and Validity of the Prostate Specific Antigen Test Prostate cancer is a frequent occurring cancer which afflicts males beginning in middle- age. According to the (American Cancer Society, 2019), prostate cancer affects men from different races however, males with Hispanic heritage, and African Americans suffer an increased morbidity and mortality rate. According to (Merriel, Funston, & Hamilton, 2018), the incidence of prostate cancer has increased over the last decade, with cell changes occurring as early as 30 years-of-age; prior to a diagnosis of advanced metastatic cancer. Although there is not a definitive diagnostic strategy to identify this prolific cancer, the Prostate Specific Antigen (PSA) test has been a benefit in the diagnosis of the disease (Bratt, & Lilja, 2015). The purpose of this paper is to discuss implications for the Prostate Specific Antigen diagnostics test, and its sensitivity, validity, reliability, predictive value as a diagnostic measure. Prostate Specific Antigen Diagnostic Tool Although prostate cancer is a predominant disease manifesting in men around 50 years of age, a definitive diagnostic screening measure was critical for use by clinicians (Bratt & Lilha, 2019). Before the 1980’s, detection of prostate cancer was typically diagnosed when symptoms of pelvic, low back and upper leg pain occurred during the late stage of the disease ( Sjoberg, Vickers , Assel, Dahlin, Poon, Ulmert, & Lilja, (2018). Diagnosis at such a late stage of the disease left providers with few methods of addressing prostate cancer due to metastasis.
