Newborn metabolic screening: The heel prick test

Printer-friendly versionPrinter-friendly version

Key points to remember

  • newborn metabolic screening (often known as the Guthrie test or heel prick test) is available to all New Zealand babies
  • the test is done 48 hours after your baby's birth (or as soon as possible after that)
  • while most infants look perfectly healthy, there are some disorders that aren't visible
  • early treatment of conditions can prevent potentially serious complications which can cause permanent damage or even death
  • to screen for these disorders, a sample of blood is collected from your baby's heel
