Hematology Board Exam Recalls
Transferrin Receptor correct answers Which laboratory result is most
useful in distinguishing iron deficiency anemia from anemia of
chronic disease?
A. Serum iron
B. MCV
C. Hemoglobin
D. Transferrin receptor
Schistocytes correct answers Replacement of cardiac valves by artificial
plastic prosthetic devices may result in enough damage and destruction to
the red blood cells to cause anemia of varying severity. This is been aptly
called the "WARING BLENDER SYNDROME". In this situation, the stained
blood smear characteristically shows:
E. Acanthocytes
F. Echinocytes
G. Codocytes
H. Schistocytes
Increased levels of hemoglobin correct answers Any turbidity in a
peripheral blood specimen will result in the falsely elevated hemoglobin
determination. Which of the following is not a potential source of
turbidity?
I. Lipemia
J. Increased leukocyte counts
K. Increased levels of hemoglobin
L. Presence of hemoglobin S
Heinz bodies correct answers Which of the following erythrocyte inclusions
cannot be stained and visualized with your Romanowsky stains?
M.Pappenheimer bodies
N. Howell-jolly bodies
O. Heinz bodies
P. Basophilic stippling
Von Willebrand disease and Bernard Soulier syndrome correct answers
Platelet aggregation studies revealed normal aggregation curves with
collagen, epinephrine, and ADP, but an abnormal aggregation curve with
ristocetin. Based on these findings, what is the differential diagnosis?
, A. Von Willebrand disease and Bernard Soulier syndrome
B. Storage pool decease, and Glanzmann thrombasthenia
C. Glanzzman thrombastenia and Von Willebrand's
D. Bernard Soulier syndrome and Storage pool disease
