Normal Repeat Newborn Screen Result
If the first screen showed a markedly elevated level of C5 a
normal second screen result is reassuring BUT does not rule out
IVA. Therefore, the metabolic physician may want to continue treating
the baby as though he/she has IVA while awaiting the results of
more definitive tests.
Once the metabolic team has confirmed that the infant does not
have IVA, it is essential to reassure the family that their baby
is well and that they should treat their baby as entirely normal.
Many people can be traumatized by a false positive result and
counseling may be appropriate. If the metabolic physician remains
concerned, however, then he/she will discuss this further with
you and may decide to continue with frequent feeds and early intervention
if the baby becomes sick. It is important to remember that this
does not mean that the baby has IVA but only that the metabolic
doctor is taking a cautious approach until definitive results
are available to keep the baby safe and well.
Abnormal repeat newborn screen result.
An elevated C5 on the second sample is very suspicious of IVA
and further evaluation by the metabolic doctor is definitely required.
The baby must be treated as though he/she has IVA while definitive
testing is carried out. See
C5 markedly elevated, probable IVA discussions in first newborn
screening result section.
