Depending on the type of testing being performed, many other factors may need to be monitored to ensure reliable test results. These include:
- Water quality
- Analytic balance calibration
- Glassware calibration
- Centrifuge calibration
- Thermometer calibration
- Incubator temperatures
- Refrigerator temperatures
- Freezer temperatures
- Expiration of reagents, standards, and controls
- Instrument maintenance
- Procedure manuals, including written step-by-step procedures of all tests performed by the laboratory
- Method selection, based on local population and clinician needs
- Normal range verification based on the local population
- Technical competencies of laboratory staff members
