S100B, a calcium-binding protein, is found predominantly in the central nervous system (CNS) and is increased in CSF and blood after CNS injury. There are two objectives to this study. Is urine S100B concentration correlated with the serum concentration of S100B in infants born at 29-36 weeks gestation. The presence and severity of intracranial pathology on S100B concentration will be investigated. Further analysis will demonstrate if birth weight, daily fluid intake, urine output, and urine creatinine influence this relationship.
