Card preview (24)
used as a basis for reference because it has known concentration
Standard
2 types of quality control
normal control pathologic control
within the reference range
normal control
outside the reference range
pathologic control
what is the difference between precision and accuracy
precision gives a producibility that results in near values while accuracy gives an exact values
DNA samples
Molecular Diagnosis (no contaminants)
only for manufacturing and never used in clinical laboratory
Technical or Commercial Grade Reagent
OSHA Requirements:
• indicate lot number • physical or biological health hazard • precautions for safe usage and storage • MSDS
calibrator and standard materials
Standard reference materials
corrects or increases the precision and accuracy of the machine
calibrator
everything is oxygen there is nothing with this water
distilled water
process of removing microorganism except nutrients
purified water
have the most stringent requirements for the test methods require minimum interference
Type I
what are the composition of type I
Trace metals Iron Enzyme Other analyses
serum in nature that has normal and pathologic control
Quality control
exact, definite and reference
Standard
can remove particulate matter for municipal water supplies
prefiltration
removes organic materials and chlorine
filtration
includes bacteria
submicron filters
2 components of quantitative results
test value and label identifying the units
SI
Syteme International D’ Unites
only system employed in many countries and provide global scientific community with a uniform method of describing physical quantities
SI system units
SI system units
metric system
7 basic units
length (m) mass (kg) quantity of a substance (mole) Time (second) electric current (ampere) thermodynamic temperature (kelvin) luminous intensity (candela)
