The biochip is an in vitro diagnostic device that quantitativelyrapidly measures serum NGAL (neutrophil gelatinase-associated lipocalin) , an biomarker of acute kidney injury.

The technology combines a disposable blood filter sensing chip, a molecular imprinting technology (bionic plastic antibody), a vacuum module,a microbead blood cell filtering device. This technique allows clinicians to early diagnose acute kidney injury. Compared with the current ELISA method, the accuracy is similar,it is fastercheaper.

This portabledisposable integrated chip takes only a drop of finger-tip blood10 minutes to quickly, easilyaccurately detect early kidney damage. Therefore, this technique enables clinicians to diagnose golden 48 hours for salvage kidneyavoid life-long dialysismultiorgan failure.
