  abstract = {{T}he {SD} {B}ioline ({R}) {I}g{G}4 rapid diagnostic test ({RDT}) detects {I}g{G}4 antibodies induced by the {O}nchocerca vol-vulus-specific antigen {O}v16. {W}e evaluated the stability of the {RDT} results over 1 month, at different time points after completion of each assay, using eluted dried blood spots collected in central {C}ameroon. {A}greement coefficients regarding positivity between 30 minutes and 24 hours, 1, 2, 3, and 4 weeks were, 96.4%, 93.4%, 93.3%, 93.2%, and 93.2%, respectively. {B}etween 30 minutes and 24 hours, 3.6% of the 15,444 tests showed inconsistent results with 81.2% of these tests changing from negative to positive, increasing {O}. volvulus antibody prevalence from 23.9% to 26.2% ({P} < 0.0001). {T}his change from negative to positive outcome was confirmed at the subsequent timepoints. {D}epending on the desired accuracy of prevalence estimates, reading time may have to be redefined more strictly.},
