Quality assurance program
|
A required program for clinical laboratories designed to monitor the quality of patient care, including quality control, instrument and equipment maintenance, proficiency testing, training and continuing education, and standard operating procedures documentation
|
|
|
certificate of waiver test
|
aboratory tests that pose an insignificant risk to the patient if they are performed or interpreted incorrectly, are simple and accurate to such a degree that the risk of obtaining incorrect results is minimal, and have been approved by the Food and Drug Administration for use by patients at home; laboratories performing only Certificate of Waiver tests must meet less stringent standards than laboratories that perform tests in other categories.
