Comparison of detection of anti-F1 IgG by dipstick and ELISA methods.
A/Seropads obtained from the long-term follow up are analyzed using both dipstick and ELISA The percent of positive samples by dipstick is plotted according to the delta OD obtained by ELISA. Both percent per class and cumulative percent of positive samples are plotted. B/Comparison of the percent of positive rat detected using ELISA and the expected positive detection using dipsticks. Using the relationship shown in A and the delta OD values represented in Figure 3A, we predicted the percent of positive rats expected using the dipstick method.
