Diagnostic Assays and Test Kits in analytical chemistry

An assay is an investigative (analytic) procedure in laboratory medicine, pharmacology, environmental biology and biology Assays applied to individuals have many uses, such as aiding and documenting pathogenicity of disease in a person, avoiding spread of disease through any means, contributing to eradication of an infection from a person to person, approving diagnosis of clinical cases, assessing infection frequency to aid risk analysis, detecting infected animals toward implementation of control actions, and categorizing animals for herd health or immune status post-vaccination. A solo assay may be validated for one or more anticipated purposes by enhancing its performance characteristics for each purpose, example. Setting diagnostic sensitivity high, with associated lower diagnostic specificity for a screening assay, or conversely, setting high with associated lower Dose for confirmatory assay.
