1b.2 Phases of Laboratory Flashcards
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
A pure solution of known extract concentration wherein the unknowns are being compared
Standard/Reference material
Control should be available in sufficient quantity to last a minimum of __ year and should be stable over a period of __ year
1, 1
Source of control:
Laboratories that prepare their own control should collect a large pool sufficient to last 1 year
Pooled control sera
In a pooled control sera, the control should be analyzed at least __ times to obtain the mean value for each constituent and the standard devations

Source of control:
They are either prepared from human serum or from bovine-based products
Commercial control sera
Refers to the sequential events necessary for an infectious disease to spread from one individual to another
Chain of infection
This is a framework that aims to minimize and control the risks associated with handling biological agents, such as pathogens in laboratory and healthcare settings
