Performance of qPCR on CSF. A, Results of performing a TsolR13 qPCR assay on unpaired CSF samples from patients during an infection with active NCC (n = 18, blue circles) and during cured NCC (n = 18, red squares), plotted as a function of Cq (y axis). A Cq of 40 is considered negative; less than 40 is considered positive. B, Results of TsolR13 qPCR on 6 subjects with paired CSF samples (subset of panel A samples) during active and cured (x axis) time periods, plotted as a function of Cq. Abbreviations: CSF, cerebral spinal fluid; NCC, neurocysticercosis; qPCR, quantitative polymerase chain reaction.
