title: Neonatal screening of glucose-6-phosphate dehydrogenase deficiency in Yanbu, Saudi Arabia.
abstract: OBJECTIVE
  To determine the prevalence of glucose-6-phosphate dehydrogenase (G6PD) deficiency in the population tested, and to evaluate the prevalence of neonatal jaundice in newborns with G6PD deficiency.
  
  
  METHODS
  Cord blood of all babies born between October 1996 and October 1998 at the Royal Commission Medical Center in Yanbu, Saudi Arabia, was screened for G6PD deficiency by fluorescent spot test. The results of screening of cord blood samples were reported to the physician in charge, and also placed on the files of the babies and their mothers. These babies were observed for 72 h and discharged if no jaundice developed.
  
  
  RESULTS
  During this two-year period, 2,505 neonatal cord blood samples from 1,278 boys and 1,227 girls were screened for G6PD. There were 50 positive results for G6PD deficiency (39 boys and 11 girls), and the prevalence was estimated to be around 2%. The sex-specific prevalence for boys was 3.05%, and for girls 0.9%. Male to female ratio was 3:1. Neonatal jaundice developed in six (12%) babies, five male and one female. All were treated with phototherapy and discharged within one week of birth.
  
  
  CONCLUSIONS
  The prevalence of G6PD is relatively high in Yanbu. Routine neonatal screening in areas with a high prevalence of G6PD in Saudi Arabia is justifiable.
