How is the sample taken?

The blood sample is taken by using a lancet to make a tiny incision in the baby’s heel. Four drops of blood are collected on a blood spot card, and the card is sent to the laboratory (www.labplus.co.nz) for testing.

The blood sample is taken with the consent of the baby’s parents or guardians. Lead Maternity Carers are responsible for talking to parents about the Newborn Metabolic Screening Programme and obtaining consent for the sample to be taken.  For more information see the pamphlet Your Newborn Baby's Blood Test.

When the blood has been tested, the leftover blood spots are stored indefinitely in secure storage by the programme unless parents/guardians or individuals ask for them to be returned. Download the form 'Return of newborn metabolic screening samples (guthrie cards) to family'

Who takes the blood sample?

The blood sample is taken by a Lead Maternity Carer, hospital midwife, or trained blood taker (phlebotomist).

Where is the blood sample taken?

The blood sample can be taken at the hospital or birthing centre, or at home.

Preparing your baby for the blood sample to be taken

You can prepare your baby for the sample to be taken by putting booties on your baby or wrapping your baby's feet up well. This makes sure that your baby's heel is warm and it is easier and quicker to take the blood sample.

Having a heel prick might cause your baby some discomfort.  You can reduce your baby’s discomfort by feeding or cuddling your baby while the blood sample is being taken.

Your Lead Maternity Carer can talk to you about other ways of keeping your baby comfortable while the blood sample is taken.
