BCPS Test Questions with All Correct Answers sensitivity formula - ANSWER "Sensitivity =true positive/(true positive +false negative) Note: more sensitive is closer to 1" specificity formula - ANSWER Specificity = True negative/(true negative + false positive) precision definition - ANSWER how consistent the test results are accuracy formula - ANSWER "accuracy=(true positive plus true negative)/total - how true the test results are" receiver operator characteristic - ANSWER "the ...

Pathological basis of IRIS To understand the immunopathogenesis of IRIS it will be crucial to elucidate the intrinsic dynamics of immune cell recovery after initiation of HAART. The numerical increase in circulatory CD4+ T-cells has been well described, but much remains to be learned about the characteristics, specificity and function of these cells. Initial descriptions showed that activated memory cells (CD4+CD45RO+) account for the early incremental phase of CD4+ cell recovery followi...
