We are back at Primary Children's today. Kai had a liver biopsy to investigate possible causes for his liver function tests, ALT and AST, going up. We should have some answers tomorrow when pathology can analyze the sample. The procedure went quickly and smoothly, we are now up on the floor recovering. He'll be here at least overnight for observation. It seems the hardest thing for Kai was being NPO for 14 hours. When he was allowed to eat shortly after waking up he chugged a pint of milk and is now sleeping that off.
