Figure 3. A four Ov antigen panel used in the standard 2 hour or QLIPS format shows 100% sensitivity and 100% specificity.

Figure 3

Each symbol represents individual samples from the 38 Ov-infected, 90 Wb, 90 Ll, 27 Ss, 72 control uninfected samples and 12 other control patients. These LIPS tests were either evaluated as a mixture in the standard format (A) or with QLIPS (B). As shown, both tests showed 100% sensitivity and 100% specificity in distinguishing the uninfected from the Ov-infected sera. The diagnostic performance related to cross-reactivity with other filarial infections was also evaluated. As described in the text, the long solid line represents the cut-off level corresponding to 100% sensitivity, while the long stippled line corresponds to the cut-off for 100% specificity with sera from the Wb cohort.
