A method for reducing the sloughing of thick blood films for malaria diagnosis

摘要

BackgroundThe gold standard for malaria diagnosis is the examination of thick and thin blood films. Thick films contain 10 to 20 times more blood than thin films, correspondingly providing increased sensitivity for malaria screening. A potential complication of thick film preparations is sloughing of the blood droplet from the slide during staining or rinsing, resulting in the loss of sample. In this work, two methods for improving thick film slide adherence (‘scratch’ (SCM) and ‘acetone dip’ (ADM) methods) were compared to the ‘standard method’ (SM) of thick film preparation.
