What is the Origin of Bioassay?

The term is a compound word combining "bio," referring to life or living systems, and "assay," meaning to test or analyze. Its use became widespread in pharmacology and toxicology when researchers realized that the chemical structure alone was often insufficient to predict a compound's true physiological impact. The earliest bioassays were developed to standardize therapeutic agents like insulin and digitalis based on their functional potency in animals.

What is the Mechanism of Bioassay?

The mechanism involves exposing a specific, sensitive biological substrate—such as a receptor-expressing cell line or an isolated tissue—to the substance being tested. The resulting quantitative biological response, which could be cell proliferation, enzyme activation, or a change in gene expression, is then measured. This measured response is compared to a standard curve generated by a known concentration of the reference material, thereby quantifying the biological potency of the test substance with high functional precision.

Bioassay

Meaning

A Bioassay is an analytical methodology used to determine the concentration or potency of a substance, such as a hormone, vitamin, or pharmaceutical compound, by measuring its effect on a living biological system. Unlike purely chemical assays that quantify mass, this technique assesses the functional activity of the compound on cells, tissues, or whole organisms. In clinical endocrinology, bioassays are indispensable for confirming that a circulating hormone level correlates with a demonstrable biological effect, which is often more relevant than the absolute quantity.
