  1. NA, not applicable because the result was negative; Pf, P. falciparum; Pv, P. vivax; Poc, P. ovale curtisi; Pow, P. ovale wallikeri; Pm, P. malariae; P.sp., Plasmodium species
  2. ICT, Immunochromatographic assay (BinaxNOW® Malaria): the appearance of T1 band alone or T1 + T2 band indicates a Pf only or a mixed infection of Pf with another species; the appearance of T2 band only indicates a Pv/Po/Pm infection
