In developed countries around the world, a baby, usually between 48 and 72 hours after birth, is pricked in the heel.
The welling drop of blood is dripped onto an absorbent piece of card. In New Zealand we collect the blood onto four circles on the card.
The small droplets of blood soak right through the card within each of the circles so that the laboratory the sample is sent to has plenty of material to work with. Below the circles the card contains the baby’s name, time of birth, gender, birth weight, gestation age, breast-feeding, and parent details.
