In a 670-patient study funded by the International Society of Nephrology, the South Africa Medical Research Council, and the University of Witwatersrand, Johannesburg, South Africa, the Nova POC StatSensor Creatinine/eGFR meter was more accurate than the central laboratory IDMS-traceable Jaffe methodology in estimating GFR when both methods were compared to measured GFR (mGFR).
The study is unique and important because of its size, and because it is one of the first studies to compare accuracy of point of care creatinine/eGFR devices to the gold standard iohexol mGFR method in a chronic kidney disease (CKD) screening programme. Other studies have only compared POC creatinine/ eGFR devices to the laboratory creatinine/ eGFR, and not to the true, iohexol measured GFR. This study was performed at University of Witwatersrand, internationally recognized for its research excellence.
CKD affects over 10% of the population in South Africa and is growing at a disproportional rate. Lack of access to central laboratory services hinders the ability to implement effective CKD screening programmes to identify early stages of CKD and prevent progression. The study found StatSensor point-of-care creatinine/eGFR was more accurate than laboratory creatinine/ eGFR when compared to mGFR and is practical for use as a CKD screening device in a resource-limited setting.
Nova’s StatSensor meter uses a miniaturized, single-use biosensor test strip and tiny capillary blood sample for blood creatinine/ eGFR testing. Incorporating patented Multi-Well™ technology, StatSensor Creatinine enables simple, rapid, and accurate assessment of renal function by fingerstick capillary blood sampling at the point of care.
“This study is very important to government health agencies, kidney or diabetes foundations, health maintenance organizations, and other health agencies who want to implement screening programmes for CKD,” said Rick Rollins, Nova Marketing Manager. “In addition to superior accuracy, the study noted that StatSensor capillary sampling is preferred by patients and offers the added benefit of eliminating the need for phlebotomy skills.”
