The "Heel Prick" test is now routinely carried out on neonatal (newborn) blood for a variety of known genetic disorders. Different countries have different policies on the archiving of this material and deidentified availability for genetic research purposes. The clinical term "phlebotomy" describes the act of drawing or removing blood from the circulatory system through an incision or puncture to obtain a sample for analysis and diagnosis.
An ultrasound study has identified the shortest depth of perichondrium was in the centre of the heel and ranged from 3 to 8 mm. In 78 of the 80 infants in the study (GA24 to 42 weeks), the distance was 4 mm or more. Showing that the standard automated lancets for preterm use (puncture to a depth of 2.4 mm) may be safely used anywhere over the plantar surface of the heel avoiding the posterior aspect of the heel. A more recent study identified the whole heel plantar surface is safe for obtaining blood in term and preterm infants of more than GA 33 weeks. A small amount of sucrose (0.012–0.12 g) can be given as an analgesic for newborns undergoing venepuncture or capillary heel-pricks.
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.

NSW Newborn Screening Programme
Each year test more than 90,000 babies and detects about 90 who need urgent assessment and treatment. In NSW and Victoria, the bloodspot cards are currently stored indefinitely.
- Phenylketonuria (PKU) - 1 in 10,000 live births (about 10 babies per year). PKU causes high blood levels of phenylalanine and severe intellectual disability. A diet low in phenylalanine, started in the first two to three weeks results in normal development.
- Primary congenital hypothyroidism - 1 in 3,500 live births (about 26 babies per year). It is caused by the absence or abnormal formation or function of the thyroid gland. This causes growth and intellectual disability if not treated. Medication with thyroid hormone started early, results in normal growth and development.
- Cystic Fibrosis (CF) - 1 in 2,500 live births (about 34 babies per year). Without treatment babies develop chest infections and often have very serious failure to thrive. Early institution of treatment greatly improves the health of babies with CF. Newborn bloodspot screening detects about 95% of babies with CF but also detects a few babies who may only be healthy carriers. For these babies a sweat test at about six weeks of age determines whether the baby has CF or is a healthy carrier.
- Galactosaemia - 1 in 40,000 births (about 1-3 cases per year). Babies cannot process galactose, a component of lactose. Life-threatening liver failure and infections can occur. A galactose-free diet instituted in the first week is life saving.
- Rarer metabolic disorders - Some fatty acid, organic acid and other amino acid defects can now be detected using Tandem Mass Spectrometry. These much rarer metabolic disorders affect about 15 – 18 babies per year. Early detection is important as diet and medications can treat most of these disorders. Without appropriate management they can cause severe disability or death.
Potential uses and access of stored bloodspots
- Identified cards may be used for family benefit or research and only with separate consent obtained before testing.
- Non-identifiable cards (identifiers permanently removed) may be used for research approved by a Health Research Ethics Committee – consent is not required.
- Parents have a right to access their child’s information. Other access requires parental consent except where there is a court order, to date this has not occurred.

State laws mandate that blood be drawn from all newborn infants to screen for health-threatening conditions.
