BACKGROUND The neutrophil gelatinase associated lipocalin (NGAL) has been identified as the most promising biomarker of acute kidney injury (AKI). This study was aimed to evaluate a NGAL immunoassay on Beckman Coulter AU 5822. METHODS NGAL Test™ (BioPorto Diagnostics A/S) is a particle-enhanced turbidimetric immunoassay. The within-and between-run imprecision were assessed on three urine samp...

OBJECTIVE To estimate relative expanded uncertainty measurement of routine clinical chemistry analytes for international organisation for standardisation 15189 accreditation. METHODS This cross-sectional study was conducted at Dow International Medical College, Karachi, from September 2013 to May 2014. During the process of international organisation for standardisation 15189 accreditation, m...

The myriad potential benefits of digital farming hinge on the promise increased accuracy, which allows ‘doing more with less’ through precise, data-driven operations. Yet, precision farming's foundational claim accuracy has hardly been subject comprehensive examination. Drawing social science studies big data, this article examines agriculture's (in)accuracies and their repercussions. Based an ...

The selective multitest Olympus AU-510 analyser was evaluated according to the recommendations of the Comision de Instrumentacion de la Sociedad Española de Quimica Clinica and the European Committee for Clinical Laboratory Standards. The evaluation was carried out in two stages: an examination of the analytical units and then an evaluation in routine work conditions. The operational characteri...

It is valuable in engineering design to distinguish between two different types of uncertainty: inherent variability and imprecision. While variability is naturally random behavior in a physical process or property, imprecision is uncertainty that is due to a lack of knowledge or information. There are many sources of imprecision in design. Sequential decision making introduces imprecision beca...
