Optical Identification of Plasmodium falciparum Malarial Byproduct for Parasite Density Estimation

Table 1

Optical densities of uninfected and Plasmodium falciparum‐infected blood samples of different parasite density at S-band, β-band, and α-band.

Blood samples		Mean optical densities (ODs) (a.u.)
		S-band	α-band	β-band	OD(β/α)(S)
u-blood		1.07^a ± 0.01	0.10^a ± 0.05	0.09^a ± 0.01	0.96 ± 0.01
i-blood (PD)	(+)	1.04^a ± 0.01	0.08^b ± 0.01	0.05^b ± 0.02	0.65 ± 0.01
	(++)	0.99^b ± 0.06	0.10^c ± 0.01	0.06^c ± 0.01	0.59 ± 0.03
	(+++)	0.71^c ± 0.03	0.15^d ± 0.03	0.08^a ± 0.01	0.38 ± 0.01
	(++++)	0.64^d ± 0.06	0.17^e ± 0.01	0.07^a ± 0.02	0.26 ± 0.01
value		<0.0001	<0.0001	<0.0001	<0.0001

Comparing u-blood samples to i-blood samples, mean ODs with different superscript along the columns are significantly different.
