C - Lesson 9 Quality Assurance Flashcards
[?] of patient samples can be a complex procedure, depending on clinical analysis, microbiological stud y, or blood banking testing among other facets of the clinical laboratory.
Laboratory testing
is one of the most important impacts on laboratory testing — it ensures both precision and accuracy of patient sample results.
Quality control (QC)
The integrity of [?] is important to both management of overall quality as well as to meeting requirements of proficiency testing.
quality control samples
Addressing QC issues is critical to the identification of potential errors with patient results, including [?] as well as [?] of testing function.
reagent matrix effects
calibration misalignment
Maintaining [?] of laboratory sample testing through quality control is vital to ensuring that patient testing is done right and that it produces accurate results.
