Assay Principle

The Gentian NGAL Immunoassay is a new particle-enhanced turbidimetric immunoassay (PETIA) for in vitro diagnostic testing of neutrophil gelatinase-associated lipocalin (NGAL) in human urine and plasma samples. The assay is rapidly performed in only 10 minutes and can be applied on a wide range of automated clinical chemistry analyzers.


Calibrator Standardization

The calibrator kit consists of 6-point pre-diluted calibrators traceable to a master calibrator. The master calibrator is assigned using another commercial method and adjusted using the Biuret method.
