What is an assay method?

An assay is a process of analyzing a substance to determine its composition or quality. The term is often used in the mining industry to refer to tests of ore or minerals. The term assay is also used in the environmental, chemical, and pharmaceutical industries. Assaying is also important in futures markets.

What do you mean assay?

Definition of assay (Entry 2 of 2) 1 : examination and determination as to characteristics (such as weight, measure, or quality) 2 : analysis (as of an ore or drug) to determine the presence, absence, or quantity of one or more components also : a test used in this analysis.

What is the difference between assay and test?

The main difference between limit test and assay is that limit test allows the identification and control of small quantities of impurities present in a substance whereas an assay mainly allows the identification and determination of the key component of a sample.

How important is an assay?

Assays must be precise, robust, and specific during use in preclinical studies and clinical trials in order to assure that drug candidates can be accurately evaluated for safety and efficacy. Validation plans assure that an assay will work reliably, even if an assay is run at different sites or by different users.

What are primary assays?

Primary assays seek to test compounds to the identified target, to screen those which could potentially be used as a drug. Various methods are used in this phase; these include high-throughput screening, focused screening and physiological screening.

What makes a good assay?

In order to give reliable, usable data the assay must be robust and reproducible. The assay should be robust in that it is not unduly affected by changes in sample preparation and handling. Equally, it should give the same results regardless of the individual operating the assay.

Is assay another word for test?

The word assay comes from the French word essai, which means “trial,” an appropriate sense for a word that means to examine for analysis. As a noun, assay means a test or appraisal to determine the components of a substance or object.

What is a research assay?

An assay is an investigative (analytic) procedure in laboratory medicine, mining, pharmacology, environmental biology and molecular biology for qualitatively assessing or quantitatively measuring the presence, amount, or functional activity of a target entity.
