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.

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)
