Calibration checks are usually completed every ______ days.

Calibration checks are usually completed every ______ days.

• A. 60 days
• B. 15 days
• C. 30 days
• D. 90 days

Answer: (C)

Calibration checks verify that instruments read accurately and produce reliable data, which is essential for maintaining quality and regulatory compliance in QA/QC programs. In many practice settings, performing this check on a monthly cycle provides a practical balance: you catch drift or any calibration issues before they impact results, while not overburdening operations with constant recalibration. This monthly cadence fits typical quality review schedules and reference standard workflows, making 30 days the standard interval. While some high-stakes or unstable instruments may require more frequent checks, and other cases might tolerate longer gaps if the device is exceptionally stable, the common practice is to set the interval at 30 days.
