Comparación de las densidades parasitarias en gota gruesa de sangre venosa versus digitopunción en el diagnóstico de Malaria Vivax. Rev Med Hered [online]. 2002, vol.13, n.4, pp.140-143.

Objective: To compare parasite density and results obtained in the thick blood film drawed from venipuncture versus finger prick in vivax malaria. Material and methods: This is an analytic cross-sectional study. We included all patients who sought medical attention in the San Martin Pangoa Hospital (Junin) between October and December 1998 because of signs and symptoms suggestive of malaria,. Every patient had two thick blood films : one from venipuncture and other from finger prick. Results: Were included 73 patients: 40 were positive for malaria plamodium. vivax diagnosed by both methods, 1 was positive only by venipuncture ( parasite density 79 parasites/ul ), and none was diagnosed only by finger prick. We had a Kappa concordance index of 0.94. There was not significant difference in the mean parasite density (5750 vs 5577 parasite/ul, respectively) Conclusion: We could not find statistically significant difference in parasite density and diagnostic performance between the two procedures.
