Introduction

Dr Robert Guthrie

A blood screening test developed by Dr Robert Guthrie (1916-95) at University of Buffalo. The test is carried out on neonatal (newborn) blood for a variety of known genetic disorders.

Blood is collected using a heelprick and spotted onto a test sheet to dry for later testing. Different countries and medical services have different policies on not only what will be tested for but also how long the test card will be kept following analysis. Check your local service for specific information.
