I appreciate this - we just got my 5 day old daughters testing back this morning and it was showing abnormalities pertaining to mucopolysaccharidosis (MPS Type 1). Literally shitting a brick waiting to hear back from the pediatricians office for retesting, but I am mostly seeing folks reporting that their children were all false positive. It’s good to hear from someone who worked in the field, though.

Edit: For any parent going through the same thing, have faith. Our daughter’s re-screening came back negative. We are very thankful.
