Analysis of the concentration, structure and functions of the cells and their precursors in the bone marrow -
Analysis of chemical constituents of plasma or serum intimately, linked with blood cell structure and functions.
Study of functions of the platelets and proteins involved in blood coagulation.

Changes in one or more of the characteristics mentioned above may produce hematological disease or manifestations. The hematology laboratory deals with routine determination of total number of cells in circulation, hemoglobin concentration, and differential count of leukocytes based on the study of the stained blood smear. Study of the stained blood smear helps in detecting morphological abnormalities of various cells seen in the peripheral blood circulation.

Tests Performed by the Hematology Lab :

COMPLETE BLOOD COUNT (CBC) Complete Blood Count tests are–

Hemoglobin (Hb) concentration
Total erythrocyte count (RBC)
Total leukocyte (white blood cell) count (WBC)
Examination of blood film (smear) for,

Complete hemogram includes, CBC tests and in addition to that,

Packed cell volume (PCV)
Mean corpuscular volume (MCV)
Mean corpuscular hemoglobin concentration (MCHC)
Platelet count

By using automatic blood cell counters it is possible to determine following additional parameters–

Red cell distribution (RDW), {As coefficient of variation (CV) or as standard deviation (SD)
Platelet distribution width (PDW)
Mean platelet volume (MPV)
Platelet large cell ratio (P-LCR)

Other routinely performed hematological tests are-

Erythrocyte sedimentation rate (ESR)
Reticulocyte count
Absolute eosinophil count
Prothrombin time
Activated partial thromboplastin time
FIBRINOGEN
FIBRIN DEGRADATION PRODUCTS
BONE MARROW EXAMINATION
