Urinary cystatin C levels have been reported elevated in tubular dysfunction.13 On view of the previous findings we have analyzed multiple markers NGAL, KIM-1, Cystatin C and IL-18 to predict AKI in selected women at time of child birth, who have risks like hemorrhage, sepsis, pre-eclampsia or eclampsia; along with standard markers i.e., rise in creatinine or decline in urinary output. The gene discussed is CST3; the disease is acute kidney injury.
