__________ is a setup that includes all test components required to perform a lab test.

• A. Test System
• B. Equipment
• C. Reagent Kit
• D. Calibration Standard

Answer: (A)

A test system is the complete setup needed to perform a lab test. It covers the instrument (equipment), the reagents (reagent kit), calibration materials, controls, and any software or consumables required to run the assay. This is why it’s the best choice when the prompt describes a setup that includes all test components necessary to perform the test—everything that must work together for accurate results is part of the test system. The other options refer only to individual parts: equipment is just the hardware, a reagent kit provides the chemicals for the reaction, and a calibration standard is used to calibrate the instrument, not to perform the test by itself.
