Abstract

The trial of external quality assessment for inborn error of metabolism was performed in 2003. A total 10 specimens for neonatal screening tests were distributed to 43 laboratories with a response rate of 83%. All the control materials were sent as a filter paper form. Each laboratory replied the test result as the screening items they were doing as a rountine test at the reception of the specimen among PKU screening, neonatal TSH, neonatal T4(total/free), galactosemia screen, homocytinuria screen and histidinemia screen. The mean, SD, and CV were analyzed.
