Module 1- Introduction To CC Flashcards
Area of pathology that is generally concerned w/ analysis of body fluids
Clinical chemistry
______ have been specifically trained in blood collection techniques and are employed primarily to collect blood specimens.
Phlebotomist
Involves the systematic monitoring of analytic processes in order to detect analytic errors that occur during analysis
Quality control
______ is directly proportional to the concentration of analyte
Absorbance
______ is the ability of a test to obtain the known target value for a sample.
Accuracy
An attractive force between substances or particles that causes them to enter into and remain in chemical combinations.
Affinity
A laboratory grade water
Blank
A _______ consists of a weak acid and conjugate base
Buffer
The ability to obtain very similar quantitative values on repeat testing of a sample
Precision
True or false: all normal values are reference range and all reference values are normal values
False
The ability to detect small quantities of a measured component.
A. Sensitivity B. Specificity
A. Sensitivity
A phase where all procedures are related to specimen collection and handling.
Preanalytical phase
A reagent grade that is suitable for use in most analytic procedures but EXPENSIVE.
Analytical reagent
A reagent grade that had been put through additional purification steps for use in specific procedures such as chromatography, atomic absorption, etc.
Ultrapure
A reagent grade that is used to manufacture drugs.
USP and NF
A reagent grade that is NOT recommended for reagent preparation unless further purification/reagent blank is included.
Chemically pure
A type of reference material that is not used routinely and has lower purity.
Secondary standard
A type of reference material that is expensive and cannot be used routinely.
Primary standard
A type of reference material that is routinely used for calibration.
CRM/SRM
A water purification method that removes all organic materials
Distillation
A water purification method that removes inorganic/ionic impurities
Deionization
A water purification method that removes excess smaller ions
Reverse osmosis
A water purification method that removes minute substances and the very first purification method done in water
Filtration
A water purification method that removes some trace organic material at specific wavelength.
Ultraviolet oxidation
A type of reagent grade water that has the highest purity and should be used immediately
