The table shows the sensitivity and specificity pattern of PSA and PAP in different groups. At BCV 4.75 ng/mL, the PSA showed 100% sensitivity and specificity whereas at BCV 4.05 IU/L PAP showed 76.2% sensitivity and 96.7% specificity. BCV at 5.8 mg/dL calcium showed 100% sensitivity in BPH versus P.Ca and prostatitis versus P.Ca.
