Therapeutic drugs are pharmacological substances administered for various treatments, typically comprising drugs with slim pharmaceutical windows. This sensitive index requires exceptionally accurate dosing to maximize the desirable effects of therapeutic drugs.
Immunochemistry is an area of biochemical research and production that is chiefly concerned with immunological responses and biomolecular mechanics. Its underlying aim is to improve global understandings of antibodies and antigens, and the interplay between the two.
Monoclonal antibodies are identical proteins cloned from a single parent cell, which are capable of binding to a specific biochemical determinant in a sample. They are used in diagnostic and pharmaceutical applications.
Screening tests are performed by immunochromatographic or lateral flow assay, or by an enzyme immunoassay (EIA or ELISA), a biochemical method for detecting the presence of drugs of abuse in a biological sample.
