Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate the differences between serum cystatin C based estimated glomerular filtration rate (eGFRcys), serum creatinine based eGFR (eGFRcreat) and measured glomerular filtration rate (mGFR) in subjects at high risk for acute kidney injury (AKI) approximately 90 days following cardiac surgery

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is an open label, single-visit study to evaluate the relationship between mGFR and eGFR based either on serum creatinine (eGFRcreat) or cystatin C (eGFRcys) approximately 90 days following cardiac surgery. No investigational study drug will be administered.
