Nephelometry involves the measurement of
A. Light scatter
B. Atomic absorption
C. Light absorption
D. Light transmission - ✔✔C. Light absorption
When light strikes a particle in a solution, it can be absorbed, transmitted, reflected, or
scattered. Nephelometry is used to measure the light scattered by particles in a
solution. It is useful for measuring protein levels in fluids, and antigen-antibody
complexes
Most potent activator enzyme is
A. Magnesium
B. Sodium
C. Potassium
D. AOTA - ✔✔A. Magnesium
Over 300 enzymes require the presence of magnesium ions for their catalytic action,
including all enzymes utilizing or synthesizing ATP, or those that use other nucleotides
to synthesize DNA and RNA
A characteristic morphologic feature in hemoglobin C disease is
A. Macrocytosis
B. Spherocytosis
C. Rouleaux formation
D. Target cells - ✔✔D. Target cells
Codocytes also known as target cells are RBCs that have the appearance of a shooting
target with a bullseye
Two consecutive values in which they are in the +2SD of the same mean or in the -2SD
of the same mean
A. 2:2s
B. 10:x
C. 1:2s
C. R:4s - ✔✔2(2s) is a Westgard multirole that indicates a reject of a run when 2
consecutive control observations are on the same side of the mean and exceed either
the mean plus 2s or mean minus 2s
Precipitation of ribosomes and RNA
A. Heinz bodies
B. Howell-Jolly bodies
C. Basophilic stippling
D. Auer rods - ✔✔C. Basophilic stippling
1. Fine stippling = polychromatophilia (production of RBCs)
2. Coarse stippling = lead poisoning
