ESR (RBC sed rate) Quiz
Preview:
Sodium citrated whole blood (blue topped tube). The diluted blood is aspirated into a calibrated ESR column and the cells are allowed to settle for a period of exactly one hour.
A. Westergren method
B. Modified Westergren method
C. Alifax Roller 20-Sysmex
D. all of the above
Serum glycoproteins
Levels increase quickly in response to injury or trauma to tissues and during infections
They are non-specific indicators of inflammation (i.e., cannot diagnose a specific infectious agent or process)
A. Acute Phase Reactants
B. Erythrocyte Sedimentation Rate
C. C-Reactive Protein
D. none
usually changes more rapidly, because it is made by the liver and secreted hours after the beginning of infection or inflammation
A. CRP
C-Reactive Protein Test
B. ESR
Erythrocyte Sedimentation Rate
test is specific for a specific disease. i.e. Rheumatoid Arthritis
A. Acute Phase Reactants
B. Erythrocyte Sedimentation Rate
C. C-Reactive Protein
D. none

A. Westergren method
B. Modified Westergren method
C. Alifax Roller 20-Sysmex
D. all of the above
period of fast settling, usually lasts about 40 minutes
A. Lag phase
B. Decantation phase
C. Packing phase
returns to normal, within a day or so, if the focus of inflammation is eliminated.
A. CRP
C-Reactive Protein Test
B. ESR
