|Abstract:||A newborn screening program for congenital hypothyroidism (CH) and phenylketonuria (PKU), a pilot study, was initiated at the Medical Genetics Unit, Department of Pediatrics, Siriraj Hospital Faculty of Medicine, Mahidol University in Bangkok, Thailand from January 1994 to December 1998, using dried blood spots (DBS). A total of 18,739 infants (out of 85,150 livebirths) were screened (22 % coverage). Three cases of congenital hypothyroidism (CH) were identified (incidence of 1: 6,246, livebirths), by enzyme linked immunosorbent (ELISA) and fluoroimmunoassays using a cut-off level of TSH >20 μIU/ml; the recall rate of 0.24%. The screening for PKU was done by fluorometric (Guthrie) and enzyme linked immunosorbent (ELISA) methods; using cut-off levels of phenylalanine > 4 mg/dl and > 3.6 mg/dl respectively, with a recall rate of 0.13%. There was no PKU found. Our study, a voluntary program, emphasizes the importance of parental education and consent; specimen collection and handling; appropriate follow-up and referral to specialists for treatment and counseling. Routine newborn screening for CH and PKU is being established to ascertain the maximum coverage, using recommendations and guidelines from this pilot study.|
