According to CLIA '88, how often must laboratory equipment be recalibrated?

1. Every month

2. Every 3 months

3. Every 6 months

4. Every year

The correct answer is: Every 6 months

Laboratory equipment calibration is essential for ensuring accuracy and reliability in test results. According to CLIA '88 regulations, certain laboratory equipment must be calibrated periodically based on the complexity of the testing and specific manufacturer recommendations. The requirement for recalibration every 6 months is grounded in the need to maintain the precision of equipment used in laboratory settings, especially in cytogenetics where slight discrepancies can significantly affect diagnostic outcomes. Regular calibration checks can help identify any drift in performance, allowing for timely adjustments to be made before inaccuracies impact patient results. While other options suggest more frequent or less frequent calibration, the 6-month interval aligns with best practices aimed at maintaining high standards of quality control in laboratories. Manufacturers often provide their recommendations, and following the CLIA guidelines helps laboratories comply with federal regulations while ensuring that diagnostic processes remain robust and reliable.
