From: A simple and inexpensive haemozoin-based colorimetric method to evaluate anti-malarial drug activity
The linear relationship between the haemozoin level of a parasite and parasitaemia. Haemozoin concentration of infected erythrocytes is presented by the absorbance at 405/750 nm of monomeric haem after conversion from haemozoin using an NaOH solution. Absorption values (means ± standard errors of triplicate wells) are plotted against parasitaemia. A well correlated, linear relationship (R2 = 0.9929) is strong evidence of the sensitivity of the method.
