Figure 1. Mechanical centrifugation and passive gravitational
sedimentation increases the sensitivity of malaria detection.
Microscopic detection of malaria was performed on patient samples
prepared either by conventional thin smear, centrifuged buffy coat thin
smear or passively sedimented buffy coat thin smear, as indicated in
x-axis. The y-axis represents the percent of patients testing positive
for malaria using each technique.
