My 3yrs 4 months age daughter's ALT level is 955.She has urin infection. What should I do for reduce alt?

ALT. Alanine transaminase or SGPT is an enzyme predominantly concentrated in the liver, and released from dying hepatocytes. Elevated levels in the bloodstream may suggest liver injury due to many possible causes. Doubt that this is related to her urinary tract infection. You need to see a pediatrician and have her examined and evaluated asap. Good luck and hope this resolves quickly.
