What is Analyte?

• A. The component, compound, element or isotope to be identified or quantified using a test or analysis.
• B. The calibration standard
• C. The testing method used to perform analysis.
• D. A chemical added to drive a reaction.

Answer: (A)

An analyte is the substance you are trying to measure in a test. It’s the component, whether a molecule, element, compound, or isotope, that you aim to identify or quantify in the sample. The rest of the sample, such as the solvent or other materials present (the matrix), isn’t the analyte. Calibration standards and the testing method are tools used to determine the analyte’s amount or presence, while reagents are substances added to drive a reaction or generate a signal. For example, if you’re measuring glucose in blood, glucose is the analyte.
