Clinical validation of glucose pump test (GPT) compared with ultrasound dilution technology in arteriovenous graft surveillance.


BACKGROUND Blood flow (Qa) measurements are an important step in the surveillance protocol of haemodialysis vascular access (VA). The glucose pump test (GPT) is a new test for Qa measurement based on the dilution of a constant glucose infusion. The aim of this study is to verify the clinical accuracy of GPT in a graft surveillance protocol with sequential… (More)
