The ratio of urinary coproporphyrinⅠto total urinary coproporphyrinⅠand Ⅲ(UCP[Ⅰ/(Ⅰ+Ⅲ)]) was analyzed by age group. The mean UCP[Ⅰ/(Ⅰ+Ⅲ)]was 0.47 at 0-6 months, 0.21 at 6 months to 1year, 0.17 at 1year, 0.13 at 2 years, 0.21 at 3 years and 0.27 at >4 years of age. In the infants<6months old, no significant correlation was noted between postnatal age and UCP[Ⅰ/(Ⅰ+Ⅲ)], whereas a significant inverse correlation was noted between corrected gestational age and UCP[Ⅰ/(Ⅰ+Ⅲ)]. Also, significant inverse correlation was observed between postnatal age and UCP[Ⅰ/(Ⅰ+Ⅲ)]in term infant group, while no significant inverse correlation was observed in preterm infant group.
Furthermore, while no significant inverse correlation was seen in preterm infants group, significant inverse correlation was seen between corrected gestational age and UCP[Ⅰ/(Ⅰ+Ⅲ)]in term infant group.
