^*The percentages have been calculated as number of cases divided by number of patients to whom the test was performed in each group. HIV = human immunodeficiency virus; HBV = hepatitis B virus; HCV = hepatitis C virus; Ab = antibody; PCR = polymerase chain reaction; 95% CI = 95% confident interval.
