Your QuestionIf TSH levels are found to be out of range in a new born baby, does this mean that the baby will have permanent or temporary deficiency?
We have identified the following information that we hope you find helpful. If you still have questions, please contact us.
Normally, if a baby's newborn screening result for congenital hypothyroidism is out of the normal range, the baby's doctor will contact the parent to arrange for the baby to have additional testing. An out of range screening result does not necessarily mean that a baby has the condition. The out of range result may happen because the initial blood sample was too small or the test was performed too early. Therefore, it is very important to go to a follow-up appointment for a confirmatory test. Follow up testing must be completed as soon as possible to determine whether or not a baby has the condition in order to begin appropriate treatment.
