When your baby is about five days old, the midwife will offer you a screening test called the newborn blood spot screen (sometimes known as a heel prick test).
This is recommended as it screens for nine rare but serious health conditions:
- Sickle cell disease (SCD)
A serious inherited blood disease which about 1 in 2,000 babies born in the UK suffer from.
- Cystic fibrosis (CF)
1 in 2,500 babies born in the UK suffer from CF, which affects the lungs and digestive system.
- Congenital hypothyroidism (CHT)
1 in 3,000 babies born in the UK suffer with (CHT), which means that they don’t have enough of the hormone thyroxine.
The blood spot screen also screens for six inherited metabolic diseases:
- Phenylketonuria (PKU)
- Medium-chain acyl-CoA dehydrogenase deficiency (MCADD)
- Maple syrup urine disease (MSUD)
- Isovaleric academia (IVA)
- Glutaric aciduria type 1 (GA1)
- Homocystinuria (pyridoxine unresponsive) HCU
These inherited conditions need to be identified and treated treated quickly as they can be life threatening or, if left untreated, can lead to severe developmental problems.
These conditions, once identified, can all be treated in a variety of ways. From medication to a carefully managed diet or physiotherapy, the treatment will be different in each case.
As parents, if either of you have a family history of a metabolic condition, it’s important to let a health professional know about this as early as possible.
How is the test done?
The midwife will take a small amount of your baby’s blood and put it onto a card which is sent to the laboratory for testing.
They will use a small device to prick your baby’s heel to get the blood. This is uncomfortable and can make your baby cry for a moment, so they may need a cuddle or a feed afterwards to reassure them.
The test is normally done in the first couple of days after birth, however occasionally this may be completed later than five days.
Sometimes the test may need to be repeated, but the midwife will explain to you if that is the case. A specialist blood spot public health nurse (health visitor) can do this if your baby is over 28 days old.
Babies can be screened for all of these conditions up to 12 months of age (except for cystic fibrosis (CF) which is up to eight weeks).
If you move into the UK from another country, you will be offered this test by a health professional, usually your public health nurse (health visitor).
Having the newborn blood spot screen may be the first decision you make for your baby, and it’s a really important one that could save their life.
If you don’t want your baby screened, you will need to discuss this with a health professional. Your midwife or public health nurse (health visitor) is also on hand to answer any questions you might have about this test.
When do you get the results?
Your public health nurse (health visitor) will give you the results when your baby is about six to eight weeks old. They will be recorded in your child’s personal health record (red book), which you will need to take along with your baby to each contact you have with a health professional.
If any concerns are identified, you will be contacted much earlier.
Leicestershire Partnership NHS Trust runs a confidential secure text messaging service for parents of children aged 0-19 years called Chat Health. The service operates Monday to Friday between 9am and 5pm, excluding bank holidays. All texts will be responded to by a public health nurse (health visitor/school nurse) within 24 hours. Outside of the service working hours, you’ll receive a message back to inform you that your text will be responded to once the line reopens.
Should you require urgent health advice in the meantime, please contact your GP, visit an NHS walk-in centre or call NHS 111. For emergencies, dial 999 or visit A&E.
