CHAPTER 1 Flashcards
HEMATOLOGYmdeals with the study of blood; includes analysis of the following:
Hemostasis
Concentration of formed elements
Morphology or structure of blood cells
Functions of the blood cells
Precursors
Death
Anemia, Leukemia
Hemocytometry
Concentration of formed elements
Branch of medicine which deals with the performance of diagnostic lab procedures, the results of which are correlated to clinical signs and symptoms of the patients
HEMATOLOGY
