CHAPTER 10: QUALITY ASSURANCE 263
quality assurance program. Quality assurance programs take into consideration
the environment and the physical aspects of the facility and how it is maintained,
from adequate lighting to proper ventilation and cleanliness. Just as soldiers
must keep their “weapons clean and their powder dry,” equipment maintenance
is a major component of a smoothly functioning and dependable laboratory.
Many breakdowns may be prevented when diligent care is taken of equipment,
supplies are properly stored to prevent deterioration, and specimens are correctly
handled and identified. Competence of personnel and ensuring adequate
staffing of various levels of staff is also of the utmost importance.
