A Small Test with Big Benefits
In order to perform the screening tests, a small blood sample will be taken from your baby. A few drops of blood are collected on special filter paper by gently pricking the heel. The blood sample is sent to the National Expanded Newborn Screening Laboratory for analysis.
Blood samples can be taken from your baby any time between one day (24 hours) and seven days old.
The best time for collection is between one to three days old (24 to 72 hours).High Risk or Low Risk ResultsWhen the sample has been analysed and results are available, one of the following will occur:
Your baby’s result is negative for all the disorders.
More than 99 per cent of the babies fall into this category. It means that your baby is at very low risk of having these disorders. The result will be filed into your baby’s medical record. On very rare occasions, a disorder may not be picked up on the metabolic screen.
A repeat sample is required.A second sample is needed for about one in 100 babies. It is usually needed because the first sample showed borderline results, which means it was not possible to tell whether or not a problem exists.
You will be contacted to arrange for another sample to be taken.Your baby’s result is positive for one of the conditions.
Having a positive result does not necessarily mean that your baby has a disorder. It only means that further testing is needed. You will be contacted to make arrangements for a metabolic physician to review and investigate. If a diagnosis is made, your baby will be given appropriate treatment right away.
It is important to know that most babies in Singapore are screened negative. These rare but life threatening disorders can usually be prevented with early diagnosis and treatment.
