What tests constitute screening?
Screening tests are required for the following conditions:
- Inborn errors of metabolism and heart diseases. The tests should be carried out with a dried blood spot sample (heel prick), within 24 to 36 hours of birth. The number and type of diseases that should be screened depends on the screening package offered in each country.
- Critical congenital heart disease. This should be tested with pulse oximetry within 24 hours of birth.
Neonates requiring supplementary oxygen should be screened after 24 hours of being clinically stable, in ambient air.
