For pediatric participants in TRIBE-AKI, a pre-operative serum creatinine concentration measured in the local hospital clinical laboratory among patients scheduled for elective cardiac surgery.

AKI participants who remain hospitalized 90 or more days after the AKI episode.

ESRD at the time of the three-month study visit.

Unable to provide at least 1.5 mL of plasma for adults at the Inpatient visit.
