A representative portion of body fluid such as serum, plasma, urine, and CSF
Patient sample
Principle used for spectrophotometry
Beer Lambert’s law
These are materials with known characteristics that are used to assess the accuracy and precision of laboratory test results
Controls
This is a comprehensive set of policies and procedures
Quality assurance (QA)
This monitors quality performance starting from the ordering of a laboratory determination to its reporting, the interpretation of results, and then application to patient care
Quality assurance
