According to CLIA '88, when must equipment also be recalibrated?

1. After a major repair

2. After every use

3. Once every year

4. Before performing routine tests

The correct answer is: After a major repair

In the context of laboratory standards established by Clinical Laboratory Improvement Amendments (CLIA) of 1988, recalibrating equipment after a major repair is a critical practice to ensure accuracy and reliability in test results. When equipment undergoes a significant repair, its functionality and measurements can be altered, which may lead to erroneous readings or results if not recalibrated properly. Recalibration involves adjusting and setting the equipment to a known standard to ensure that it functions correctly and delivers precise measurements. This step is essential after major repairs, as the integrity of the equipment can be compromised, either through physical changes or by replacing components that affect performance. Other practices, such as recalibrating after every use, once a year, or before performing routine tests, generally do not align with standard laboratory practices. For instance, recalibrating after every use could be excessive and impractical, while yearly recalibrations may not catch issues that arise from repairs. Recalibrating before routine tests can be important, but it does not specifically address the necessity following major repairs, which is a definitive requirement. Thus, the practice of recalibrating after a major repair ensures adherence to quality control standards and optimal performance of laboratory equipment.
