Prozone effect in 17 HRP-2 based malaria rapid diagnostic tests. Prozone effect was defined as an increase in HRP-2 line intensity upon dilution of the sample as observed in two tests and read by two observers. In case of prozone effect, line intensities for the undiluted samples are recorded in the Table, they are intensities are categorized as Negative, Faint, Weak, Medium and Strong. For test line intensities, consensus readings of duplicate test read by two readers were considered. If no consensus was reached, both categories are listed.
