A group of specimens analyzed and reported together is called what?

• A. Calibration Curve
• B. Analytical Run
• C. Internal Standard
• D. Levey-Jennings Chart

Answer: (B)

Grouping several specimens to be measured in one continuous sequence under the same method and instrument conditions is called an analytical run. This concept matters because all results in a run share the same calibration, reagents, and performance, making it possible to assess within-run precision and detect any drift or issues that affect that batch. The other terms refer to different ideas: a calibration curve translates instrument signals into concentrations, an internal standard is a known substance added to samples to correct for variability, and a Levey-Jennings chart tracks control values over time to monitor instrument performance, not the grouping of specimens analyzed together.
