Hello. Welcome to hcm.
causes inflammation and scarring of liver
which causes bile produced,not to exit the liver causing it to spill in to blood which can be seen as bilirubin
To rule out if there is chronic or acute hepatitis
,you can get IgM and IgG HAV tested. Other tests like MRCP can be done to rule out obstructive diseases in bile duct which would have occured along with infection.
If there is only infection,then management is symptomatic and giving time for liver to heal itself so that slowly the bilirubin will subside.
All the best
