RDT Quiz A Q4 Shown below is an RDT test. This uses a pan-malarial antibody (labelled Pan) and a P.falciparum species-specific antibody (labelled Sp). The test has been used to assess a patient and the positive bands are shown on the figure. Which of the following interpretions can reasonably be made? (select one or more options) Single species: P.falciparum Single species non-P.falciparum Two species possible including P.falciparum Two species possible not including P.falciparum P.falciparum with HRP2 deletion This test cannot be reported Explanation of correct answer (click "Expand") Short answer taken from section "Interpretation of multi-band RDT Tests" (see this section for full details and links). Most likely interpretation: The single species detected by the species specific band is present (this same species is also detected the pan-malaria band) Less likely but possible interpretations: There are two species present in the sample (likelihood depends on country of origin, but is less likely) There is a false positive result causing both bands (unlikely) Go to next question (5 of 5)
