Intra assay variation
WebApr 1, 1999 · Interassay variation was assessed from 30 determinations, measured on separate days, and intraassay variation was assessed from 10 determinations, measured on a single assay. Intra- and interobserver variation for bioimpedance measurements were assessed from triplicate measurements by three observers on two subjects on a single day. WebThe sensitivity of the assay was 100 pg/ml, and the intra- and interassay coefficients of variation were 4.4% and 16.7% respectively at serum ghrelin concentrations of approximately 3000 pg/ml. Plasma NPY levels were also measured by use of an RIA technique (20). The sensitivity of the assay was 1.9 pmol/l and the intra- and interassay ...

WebJun 14, 2024 · The assays showed very low variability, both in terms of repeatability (intra-assay variation) and reproducibility as intermediate precision (inter-assay variation), … WebThe most beneficial storage conditions were strips that were not stored (+21.8%), or underwent 'wet' storage (+11.1%). Protein recovery was the highest in 400 mu L extraction buffer and independent of protein molecular weight. This study helps to explain inter- and intra-variability that is often seen with tear biomarker research.
