Results of tests by the indirect fluorescent-antibody (IFA) technique of serum samples were compared with results from microscopical diagnosis of blood films from two groups of patients with malaria: 159 persons infected with (120 cases) or (39 cases); and from 79 servicemen who had attacks of vivax or falciparum malaria after returning from Vietnam. In the 159 persons, the parasite species was correctly identified by the IFA test in 76.7%. fourfold or greater differences in titer being used as a basis for speciation, as compared to identification of species by blood film examination. In the second group, the same criteria were used and correct identification was obtained in 81% of the cases from 0 to 14 days after the onset of symptoms, and in 96.2% from 15 to 60 days after the onset of symptoms. The IFA test was unreliable for speciation in tests of serum samples taken 6 months after the onset of symptoms.
