Question
How high is the passing rate for the follow-up test for my baby’s phenylketonuria? The first test was a blood test, and the indicators were slightly elevated at 6 and 7. We have to wait another week for the results. I want to understand this a bit better. There’s no history of this kind of dementia in my family. Will the follow-up test pass?
Answer
If there’s a family history, the chance of passing is not high. The key is to find the cause, treat it according to symptoms, and the sooner the treatment, the better. Mainly, we need to prevent irreversible harm to the nervous system. Primarily, we use phenylalanine-based formula milk. As the baby grows up, we can gradually provide low-phenylalanine diets. And it’s essential to regularly check the concentration of phenylalanine, at least until adolescence. Lifelong treatment would be better.
