Pathogen immunity in 42 children and adolescents from Kinshasa with paired plasma/DBS considering different cut-offs. The plasma cut-off provided by VIRCELL for each pathogen is shown in Table 1. Options A and B, with the VIRCELL cut-off according to Table 1. Options C and D, with the maximum specificity or optimum cut-offs calculated for each pathogen, as indicated in Table 3. Statistically significant differences found: *p = 0.01–0.03; **p = 0.001–0.003; ***p < 0.0001.
