Performance of qPCR on plasma. A, Results in Cq value (y axis) of unpaired plasma samples from active NCC (n = 16, blue dots), cured NCC (n = 30, red squares), and non-NCC (echinococcosis, n = 5; schistosomiasis, n = 2; non–cestode-infected n = 18, green circles) subjects tested by TsolR13 qPCR. A Cq of 40 is considered negative; less than 40 is considered positive. B, There were 5 subjects who had paired plasma samples (subset of panel A) from active and cured time points (x axis), with the results of TsolR13 qPCR shown as a function of the Cq value. Abbreviations: NCC, neurocysticercosis; qPCR, quantitative polymerase chain reaction.
