What does sample assay mean?
A quantitative determination of the amount of a given substance in a particular sample. Assays are regularly used to determine the purity of precious metals. They can be performed by wet methods or dry methods.
What is an assay in medical terms?

What is assay report?
An assay is an analysis designed to measure and test the composition in ore, alloys, and precious metals. With respect to precious metals, specifically silver and gold, it is a way to make sure that all the coins or bars produced in a mint meet the correct purity standards and content.
What is an assay in biochemistry?
Definition. A biochemical assay is an analytical in vitro procedure used to detect, quantify and/or study the binding or activity of a biological molecule, such as an enzyme.
Is an assay a blood test?
Various types of assay have been developed for use in blood screening over the past three decades. The assays most commonly in use are designed to detect antibodies, antigens or the nucleic acid of the infectious agent.
Why do we perform assay?
How do you prepare assays?
When you’re preparing to develop a new assay, here’s a quick checklist for the process.
- Specify molecule and state precisely what property of that molecule is to be tested.
- Identify the molecule source.
- Determine the stability of the molecule during the course of the assay.
- Determine number of samples included in assay.
