38 | 71 (55–83) | 60 (43–75) | 82 (65–92) | 97 (87–100) | 99 | 97 (91–99) | 77 (67–84) | 40 (30–51) | 30 (22–40) |
Data are percentages (95% confidence intervals). The positive and negative predictive values of the assays are as follows: PCR, 90 and 90%; IgM + IgG MIF, 35 and 97%; IgM MIF, 50 and 82%; IgG MIF, 34 and 85%.
