Comparison of microscopy and LAMP for malaria parasite detection and species identification, Thailand^*

Parasites detected by microscopy and LAMP (No. samples)†
Microscopy	LAMP
Plasmodium falciparum (19)	P. falciparum (18), negative (1)‡
P. falciparum plus P. vivax (1)	P. vivax (1)§
P. vivax (39)	P. vivax (37), P. falciparum plus P. vivax (1),¶ Genus specific (1)§
P. vivax plus P. ovale (1)	P. vivax (1)§
Negative (50)	Negative (50)

^*LAMP = loop-mediated isothermal amplification.

^†Each row shows results obtained from identical blood samples. LAMP results that were not concordant from those of microscopy are shown in bold.

^‡Negative for P. falciparum by nested polymerase chain reaction.

^§Positive for P. vivax by nested polymerase chain reaction.
