Thanks for query,
It is possible that typhoid
and increased S. bilirubin
might be different entities.
It might be due to Ciprofloxacilin which is important for treatment of typhoid.
She might be suffering from Infective hepatitis
So go for Liver
function tests like S.G.O.T.,S.G.P.T.,Direct and indirect S.Bilirubin. which will give exact idea about this problem.
Meanwhile consult your doctor and any change in antibiotic for typhoid.
Ok and bye.
