AKI is a common, costly and potentially fatal complication in hospitalized patients.1 In comparing patients with AKI to patients without AKI, hospital and the intensive care unit (ICU) lengths of stay double, as do costs of care and readmission rates.

Moreover, death rates at one year are higher among patients with AKI alone, compared to those patients with heart attack alone.

Identifying risk of AKI is paramount because AKI usually lacks signs and symptoms6 and can potentially result in irreversible kidney damage if recognition is delayed.1 In clinical studies, the NEPHROCHECK Test identified the majority of patients that developed moderate to severe AKI within12 hours of assessment.

"The availability of a test to identify patients at risk of developing moderate to severe acute kidney injury can allow for the recognition and closer management of these patients," said Dr. Kianoush Kashani of the Mayo Clinic.

"A test designed to achieve high sensitivity, such as the NEPHROCHECK Test, allows for the identification of the majority of patients at risk for developing moderate to severe acute kidney injury."

The NEPHROCHECK Test result, called the AKIRisk Score, has significant ability to distinguish patients with AKI from those without AKI. Based on results from clinical studies, patients with a positive AKIRisk Score (greater than the cutoff of 0.3) have a one in four to a one in three chance of developing moderate or severe AKI within 12 hours of assessment.

To calculate the AKIRisk Score, the NEPHROCHECK Test System measures the concentrations of two urinary biomarkers using the ASTUTE140 Meter. The two novel biomarkers — tissue inhibitor of metalloproteinase 2 (TIMP-2) and insulin-like growth factor binding protein 7 (IGFBP-7), are thought to be involved in G1 cell cycle arrest in the earliest phases of injury.

In July 2014, Ortho-Clinical Diagnostics, Inc. entered into a strategic collaboration with Astute Medical, Inc., the developer of the NEPHROCHECK Test System, to become the exclusive sales agent for Astute Medical’s NEPHROCHECK Test and the ASTUTE140 Meter in the United States and in certain countries of the European Union.

"NEPHROCHECK provides customers with a simple, yet innovative new approach to help healthcare providers assess the risk of acute kidney injury, which leads to poor patient outcomes and increased hospital costs," said Robert Yates, Ortho Clinical Diagnostics’ Chief Operating Officer. "Ortho Clinical Diagnostics is focused on bringing targeted solutions to our customer that address unmet clinical needs and drive improvements to quality care."
