There is a wide variation in time intervals to peak and resolution of disease. This patient presented on day 10 and disease resolved by day 151.;Biochemistry dynamic profile of patient presenting early;Children with idiopathic neonatal hepatitis have more severe disease if their presenting GGT levels are ≤ 100 IU/L However, the outcome appears to be good if the GGT becomes raised at a later point of disease Further research is required to elucidate the cause of low GGT level
