Neutrophil Gelatinase-associated Lipcalin(NGAL): A Novel Blood Marker for Determining the Risk of Developing Contrast-Induced Nephopathy

EDTA anti-coagulated blood samples will be drawn at eight different time points from within 1 hour prior to first contrast administration through 48 hours. These blood samples will be processed to plasma at the clinical site, frozen and shipped to Biosite for storage and testing of Triage NGAL and serum creatinine. The results of these assessments will be blinded to the medical team during the study and will not impact the medical management of the subject. Any additional serum creatinine measurements obtained by the medical team as part of routine care as well as need for dialysis, hospitalization, major adverse cardiovascular events and mortality will be recorded through Day 30.
