Relative merits of thick or thin films in malaria diagnosis


COMPARISON OF THICK AND THIN FILMS
Feature Thick Film Thin Film
Sensitivity for detection Higher: detects low parasitaemia ~5–10 parasites/µL Lower: generally needs ~50 parasites/µL for reliable detection)
Species Identification Poor: RBC morphology lost and species-specific features may be difficult Excellent: Parasite morphology and RBC characteristics are readily observed
Quantification of parasitaemia Difficult: requires estimation so is imprecise Easier: parasites can be counted per number of RBCs
Preparation and staining Longer: requires air drying before careful staining to avoid artefact Faster: films are fixed and stained immediately with clearer morphology
