Newborn Blood Spot Screening

Newborn Blood Spot Screening

Babies born in Alberta are tested for certain treatable conditions after birth. This screening test is different from those done during pregnancy.

The newborn blood spot screen is done by Alberta Health Services (AHS) through Alberta’s Newborn Metabolic Screening (NMS) Program. The program works to prevent health problems and improve the health of Alberta babies through early diagnosis and treatment of certain treatable conditions.

What is a newborn blood spot screen?

This is a blood test that is done on newborn babies to test for treatable conditions that you, your doctor, or midwife can’t see by just looking at your baby.

Finding and treating these conditions early can help prevent health problems. This can improve your baby’s overall health and may even save your baby’s life.

What conditions does the newborn blood spot screen look for?

This screening test looks for treatable conditions that include:

  • metabolic conditions - cause problems with how your body uses food to grow and develop
  • endocrine conditions - cause problems with how your body makes hormones
  • cystic fibrosis - affects your lungs and digestive system
  • sickle cell disease - affects your blood and causes damage to heart, lungs, and kidneys
  • severe combined immunodeficiency - affects your immune system or ability to fight infections

What causes these conditions?

These conditions are often genetic. Usually babies are born with them when they inherit a gene, which has a change in it, from both parents. This change stops the gene from working properly. Sometimes the conditions can happen for no reason. The treatable conditions aren’t caused by anything that happened during pregnancy.

There may be no signs of these conditions at birth. It’s important to remember that many conditions can’t be seen by looking at your baby.

What happens during newborn blood spot screening?

The screening has 3 steps:

  1. Collecting a few blood drops from a heel poke.
  2. Testing the blood spots for certain treatable conditions.
  3. Helping your baby get other tests and treatment if they need it.
  4. When should this screening be done?

    The best time for the newborn blood spot screen is when your baby is between 24 and 72 hours old. Ideally, the blood spot screen happens at the hospital before your baby goes home. It’s important to find these conditions as early as possible.

    What will the screen results show?

    The screen results show if:

    • your baby’s screen is normal
    • your baby needs to have the screen done again
    • your baby needs more tests to find out if they have one of the treatable conditions

    What if I have more questions about the screen?

    Talk to your public health nurse, doctor, or midwife if you have any questions about newborn blood spot screening or Alberta’s Newborn Metabolic Screening Program. You can also go to Newborn Metabolic Screening Program | Alberta Health Services.

    Is my baby’s privacy protected?

    Yes, health information is collected, used, and shared (disclosed) by following the laws of Alberta’s Health Information Act. Your baby’s health information is protected in a secure, private, and confidential place.
