Early risk assessment of moderate to severe acute kidney injury

Used in the acutely ill, the NEPHROCHECK® test helps clinicians identify kidney stress early, allowing them to confirm or optimize their treatment strategy while mitigating the risk of acute kidney injury for the  acutely ill.

  • Early “alarm system” specific to kidney stress, before damage occurs
  • High sensitivity and negative predictive value
  • Time to Result < 1 hour


In intensive care units, critically ill patients are commonly exposed to nephrotoxic drugs (such as antibiotics, vasopressors, diuretics and radiocontrast agents) that help preserve their key vital functions but can cause serious complications, up to permanent kidney loss. Acute Kidney Injury (AKI) occurs in more than 50% of patients on day 1 of their stay1. It is associated with a 10-fold increase in hospital mortality rates2, while hospital costs, length of stay and 30-day re-admissions can become at least twice as severe3,4.

AKI is a silent killer, with no immediate specific signs or symptoms. Diagnosis with commonly used kidney function tests often comes too late6. The good news is that both acute and long-term kidney damage can be avoided if the risk is identified and managed early.5 What if you had an opportunity to intervene proactively and preserve your patient’s renal function?

NEPHROCHECK® is an innovative test that detects kidney stress prior to actual damage, when intervention can still make a difference. It is intended to be used as a risk assessment test, in conjunction with clinical evaluation, to aid in identifying patients at risk for developing moderate or severe AKI within 12 hours.

With this early warning, intensivists may either rule out patient with confidence, or implement a series of nephroprotective measures to significantly improve patient outcomes and reduce costs7,8, avoiding the need for dialysis and other comorbidities that typically result from AKI.

The kidneys’ alarm system



The NEPHROCHECK® test detects TIMP-2 (tissue inhibitor of metalloproteinases-2) and IGFBP-7 (insulin-like growth factor-binding protein 7).

These novel urinary biomarkers are produced by stressed kidney cells as an early warning signal, before the onset of acute kidney injury.

Specific to kidney stress, they are not affected by any of the usual co-morbidities (such as sepsis, trauma, chronic kidney disease or cancer).9

Testing strategy

The NEPHROCHECK® test provides a single quantitative result, the AKIRISK score.

Test result


What does it mean?

≤ 0.3


  • Low risk of developing moderate to severe AKI within 12 hours 
  • The same treatment protocol may be continued
  • The patient should recover fast & be discharged rapidly from the ICU

> 0.3 


  • Indication of kidney stress: the patient might develop moderate to severe AKI within 12 hours
  • An AKIRISK score in the interval [0.3 – 2.0] is expressing a higher risk of developing a moderate/severe AKI event than a score below the 0.3 cut-off9
  • Refer to the KDIGO bundle10 to adapt medication and patient management and prevent further progression
