TABLE 1.

Estimated hemozoin concentrations in blood from children with malaria^a

Severity of malaria	Geometric mean no. of parasites/μla	Hemozoin concn (fg/pRBC)b	Estimated hemozoin concn in blood from children with malaria (μg/ml)c
Mild	41,369	47	1.9
Severe	275,005	47	12.9

^aCalculated from blood of children with mild (n = 17) and severe (n = 12) malaria (21).

^bCalculated from cultured parasites (10).

^cDetermined by multiplying the concentration of hemozoin (in femtograms per pRBC) obtained from cultured parasites by the geometric mean number of parasites per microliter in children with mild and severe malaria.
