Hematology Flashcards
Deals with enumeration of cells in the blood and other body fluids.
hematology
Duties or Test perfomed in hematology
- Complete blood count
- Peripheral blood smear
- Preparation and staining of buffy coat
- Preparation and staining of body fluids
- Preparation and Staining of Bone marrow
- Total cell count and Differential count for Body fluids
- Coagulation Studies
- Clotting time/ Bleeding time
- ESR (Erythrocyte Sedimentation rate)
CBC
a. RBC count
b. Hemoglobin
c. Hematocrit
d. RBC indices (MCV, MCH, MCHC)
e. Total White blood cell count
f. White blood cell differential count (NEB.LM)
g. Platelet count
Features of a well made blood smear:
2/3 or 3/4 length, finger shaped
continuous, regulated process of blood cell production that includes cell renewal,
proliferation, differentiation, and maturation.
HEMATOPOIESIS
consists of the bone marrow, liver, spleen, lymph
nodes, and thymus
