- Why have their been delays in the newborn screening test I ordered?
- You may experience a delay in receiving the newborn screen results due to adrenoleukodystrophy (ALD) testing. This additional test is done at the Genetic Disease Laboratory. A 1st tier and 2nd tier testing for ALD is a measurement of the very long chain fatty acid (C26:0 lysophosphatidylcholine) done on the NBS. If both tiers are not in range, tier 3 of ABCD1 gene sequencing will be done to identify ALD causing variants. You’ll be notified if additional testing is necessary.
