How is Propionic Acidemia diagnosed?
Most states provide comprehensive newborn screening (CNBS) for Propionic Acidemia. Potential late onset cases can be identified using this type of testing. Such cases are verified through additional blood and urine tests. Diagnosis of acute onset cases is typically made in the intensive care unit when newborns go into a metabolic crisis within the first few days of life. If the baby isn’t screened at birth, late onset cases may present themselves throughout the first few months of life with failure to thrive, vomiting, trouble feeding, and/or low muscle tone. If the symptoms aren’t addressed, late onset cases are usually diagnosed in the ER after a traumatic metabolic crisis. Early detection and treatment of propionic acidemia can potentially improve the prognosis of the affected individual.
