what can a high lactic acid level { 25 } mean in a 7 month old baby mean she has a hx of colic and constipation and her thyroid levels are wnl. Unfortunately, her mile stones are quite delayed. Poor head control, cant sit up independently etc.... .This is not my baby, but my dear friend s. We are health care professionals but dont work w pediatrics.
It could be some storage disorders, kindly evaluate for storage disorders if the baby has any organomegaly.
