Bioassays are typically conducted to measure the effects of a substance on a living organism and are essential in the development of new drugsand in monitoring environmental pollutants. A bioassay is a procedure for determining the concentration, purity, and/or biological activity of a substance (e.g., vitamin, hormone, plant growth factor, antibiotic, enzyme) by measuring its effect on an organism, tissue, cell, enzyme or receptor preparation compared to a standard preparation. • Bioassay might measure a diff aspect of the same substance compared to chemical assay [Eg testosterone & metabolites Types of Bioassays [1] Quantal Assays [ Direct endpoint ] – Elicits an ‘All or None’ response in different animals – Eg. 1.

In the absence of a good chemical method of sufficient sensitivity (as with analytical chemistry) a bioassay can be necessary. A bioassay provides only an estimate of the potency of the unknown; the precision of the estimate should always be determined, using the data of the assay.
