Laboratory hematology encompasses all blood tests, and provides both quantitative and qualitative characteristics of analyzed blood.

• Quantitative analyses - give the number of blood cells (erythrocytes, leukocytes, thrombocytes), concentration of hemoglobin, hematocrit, and erythrocytic and thrombocytic indices.
• Qualitative analyses - establish morphological characteristics of cells in the blood and blood-forming organs (DBP = differential blood picture, myelogram, splenogram), the presence of foreign elements in cells.

Complete blood count
Complete blood count (CBC) determines:

• White blood cell count (WBC)
• Red blood cell count (RBC)
• Hemoglobin concentration (Hb)
• Hematocrit (Hct)
• Thrombocyte count (platelet count; Plt)
• Red cell indices (MCV, MCH, MCHC, RDW)
• Thrombocyte indices (MPV, PDW)
• DIFF (differential white blood count).
