My son, who is 7, takes 15mg/week of methotrexate is normal ALT figure is 27. It has jumped up to 60 this month which is just above normal the normal range where the maximum figure is 50. I have emailed his rheumy nurses and left a message but know it will be a while before they get back to me. We are not due to see his consultant for a couple of weeks. Should I be worried or jumping up and down more for him to be seen sooner. Does anyone know.
