Assay parallelism
WebAug 13, 2013 · Proper parallelism assessment for biomarker assays during development and validation enables appropriate data interpretation. Also, while performing parallelism assessment, one could gather clues regarding other key assay parameters such as selectivity, sensitivity and assay minimum required dilution (MRD).
