    When newborn babies are about a week old a blood sample is taken from their heel. This is sometimes referred to as the heel prick test. Blood from the baby’s heel is dropped onto a special type of filter paper called a Guthrie card and stored as a series of blood spots. A number of tests are then carried out on these blood spots for the purposes of newborn screening. These tests are often called newborn blood spot screening to distinguish them from other types of newborn screening, such as hearing screening, which don’t involve this blood test. These blood spots can be stored for very long periods of time.
