Paediatric Acute Hepatitis
Following an increase in cases of acute hepatitis of unknown origin in children, for patients <16 years old, we have updated our critical limit for urgent communication for ALT to >500U/L in primary and secondary care (effective 25/04/2022).
Our critical communication cut off for AST remains unchanged at >525U/L (adults and paediatrics).
If you have any queries, please do not hesitate to get in touch.
