H-FABP for Acute Kidney Injury Testing

Revealed by Randox

A new testing application for the biomarker Heart-Type Fatty Acid-Binding Protein (H-FABP) has been announced by global diagnostics company Randox Laboratories.

Whilst H-FABP is most commonly recognized as an early biomarker of myocardial infarction, the assay’s clinical utility in cardiac surgery associated acute kidney injury (CSA-AKI) is notable. Studies have shown that patients who developed AKI following cardiac surgery had elevated levels of H-FABP both pre-and postoperatively compared to the patients who did not.


Susan Hammond, Randox Product Specialist, explained the new application for H-FABP;

“Cardiac surgery-associated acute kidney injury (CSA-AKI) is a well-recognized postoperative complication of cardiac surgery and is the second most common cause of AKI in the intensive care unit (ICU) – occurring in up to 30% of patients.

“Several AKI studies exist focusing on the measurement of H-FABP levels before, during and after cardiac surgery, one of which found that the post-operative H-FABP levels in patients who experienced any AKI increased 8-fold. It was also noted that the levels of those with severe AKI increased 13-fold and that 10.8% of patients who died from subsequent AKI all had elevated pre-operative levels of H-FABP.

“The Randox H-FABP assay is therefore an independent marker of AKI following cardiac surgery, and can furthermore be used as a CSA-AKI risk assessment assay even in advance of the procedure.”

It has been identified that certain patient groups are more susceptible to CSA-AKI and vulnerability can depend on age, sex, pre-existing cardiac dysfunction, pre-existing chronic kidney disease (CKD), previous cardiac surgery or comorbidity.

Susan Hammond added;

“The ability to include biomarkers that aid in the risk assessment and treatment plan management of a patient is significant.  Utilizing H-FABP alongside traditional biomarkers to assess CSI-AKI risk allows the clinician to gain stronger clinical insight in how to improve patient outcomes.”
