Five hundred consecutive newborns were screened for erythrocytic G6PD deficiency in cord blood. The overall incidence of G6PD deficiency was found to be 2.80 percent. The incidence of G6PD deficiency was higher among males (3.77%) compared to females (1.44%). The incidence of erythrocytic G6PD deficiency was higher in Muslims (16.67%) compared to Hindus (2.63%). No definite relationship of erythrocytic G6PD deficiency was observed with consanguinity. Fifty per cent mothers of G6PD deficient newborns were also found to be G6PD deficient. Among brothers and sisters of G6PD deficient children the incidence of G6PD deficiency was 50.00 and 9.10 per cent respectively. There was no significant difference in the incidence of hyperbilirubinemia between erythrocytic G6PD deficient and non deficient newborns.
