Screening tests are done using 2 different samples:

  • a blood sample;
  • a urine sample.

Blood sample

A few drops of blood are taken from the baby’s heel in hospital or at the birthing centre by a nurse or midwife. This is done within 24 to 48 hours of the child’s birth.

Urine sample

A small amount of urine is taken from the baby’s diaper at home by the parents on Day 21 after the child’s birth using the material provided by hospital staff or the midwife.

Steps to follow

Collect the urine sample in the morning, if possible. Also, to avoid affecting the test results, do not clean your baby’s bottom with commercial baby wipes or apply any cream, oil or powder before you collect the sample.

  1. Put the absorbent pad provided in the diaper with the plastic film against the diaper surface.

  2. Remove the pad as soon as your child has urinated to avoid contamination of the pad by stool.

    If the pad is contaminated by stool, repeat the procedure using the second pad provided.

  3. Remove the blotting paper from the yellow form and put the urine-filled pad on it. Press firmly so that both sides of the blotting paper are soaked.

  4. Leave the blotting paper to dry on a clean, dry surface.

  5. Fill out the yellow form. Write down the baby’s approximate weight, type of feeding and any other information requested. Confirm your address and telephone number.

  6. When the blotting paper is dry, put it in the reply envelope with the yellow form.

  7. Put a stamp on the reply envelope and mail it.
