American Society for Clinical Pathology (ASCP) Histotechnician Certification Practice Exam

How often should the performance and speed of centrifuges be checked?

1. Every month

2. Every 2 months

3. Every 3 months

4. Every 6 months

The correct answer is: Every 3 months

The performance and speed of centrifuges should be checked every 3 months to ensure they are operating correctly and consistently within the required specifications. Regular monitoring at this interval allows for the detection of any potential issues that could affect the accuracy and reliability of laboratory results. Centrifuges are critical instruments in pathology and histology labs as they separate components based on density and are used in various tests, including blood sample preparation. Regular performance checks help to maintain compliance with laboratory standards and protocols, ensuring that centrifuges provide optimal results and prolonging their lifespan through preventive maintenance. A schedule of every 3 months strikes a balance between ensuring consistent performance and not being overly burdensome on laboratory resources or management. Shorter intervals may not provide significant additional benefit, while longer intervals could risk performance degradation that could affect sample handling and diagnostic accuracy.
