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.”

Global diagnostics company Randox Laboratories has unveiled an innovative new test for the risk assessment of cardiovascular disease at this year’s AACC Clinical Lab Expo in Anaheim, California. The test detects and measures the cardiac biomarker sPLA2-IIA. When raised, sPLA2-IIA is an independent indicator of primary and secondary cardiovascular risk. The release of the new automated sPLA2-IIA assay from Randox adds to the company’s extensive cardiac and lipid testing panel, that are all designed for use on biochemistry platforms.
Susan Hammond, Product Specialist, commented;
“By 2030, it is estimated that almost 23.6 million people globally will die from CVD, with heart disease and stroke projected to remain the leading causes of death. This confirms that early diagnosis is an essential step in reducing the number of individuals affected. The continued investment and addition of early biomarkers that add clinical utility in cardiac risk testing is key to refining clinical assessment, and ultimately the treatment plan required.”
sPLA2-llA, a member of the secretory phospholipase A2 family, offers clinical utility as an inflammatory biomarker specifically in the diagnosis of CVD risk. As the prototypic member of the group II sPLA2 subfamily, it is known as “inflammatory sPLA2”.
Susan Hammond continued;
“sPLA2 -llA hydrolyses phospholipids from membranes, native lipoproteins and oxidized protein. As it is not bound to Apolipoprotein B its impact is more significant. Hydrolysis produces biolipid mediators lyso phospholipids and fatty acids along with Arachidonic acid which then accelerates inflammatory mediators. Due to increases in lipid and inflammatory mediators, increased cholesterol rich foam cells form- adding to plaque formation. sPLA2-IIA reduces biomarkers such as HDL-C capacity to mediate cellular cholesterol efflux from these lipid loaded macrophages.”
