Complete Blood Count (CBC).

• Diagnosis of anemia, infections, inflammatory processes, allergies, coagulation disorders, bone marrow diseases.
• Assessment of disease severity and progression.
• Monitoring the effectiveness of treatment.
• Screening during preventive examinations.

• Blood is drawn from a finger or vein, usually in the morning on an empty stomach.
• Avoid alcohol 24 hours before the test, do not smoke for 30 minutes before, avoid physical exertion and stress.
• It is important to inform your doctor about any medications you are taking, as they may affect the results.

• Reference ranges depend on sex, age, and physiological state (e.g., pregnancy).
• Deviations from the reference range should be assessed in combination with clinical presentation and other tests.
• Self-interpretation may be inaccurate and requires consultation with a specialist.

• Hemoglobin increased — blood thickening (dehydration), smoking, high altitude, chronic lung diseases, erythrocytosis, kidney tumors.
• Hemoglobin decreased — anemia, blood loss, iron deficiency, vitamin B9 and B12 deficiency, chronic diseases, pregnancy.
• Erythrocytes increased — hypoxia, smoking, stress, dehydration, erythrocytosis, polycythemia, tumors.
• Erythrocytes decreased — anemia, erythrocyte destruction, chronic inflammation, renal failure, pregnancy.
• Hematocrit increased — blood thickening, dehydration, burns, erythrocytosis.
• Hematocrit decreased — anemia, hyperhydration, pregnancy, chronic kidney or liver disease.
• Leukocytes increased — infections (usually bacterial), inflammation, leukemia, trauma, stress, allergies, postoperative period.
• Leukocytes decreased — viral infections, immunodeficiencies, aplastic anemia, cytostatic drugs, autoimmune diseases.
• Neutrophils increased — bacterial infections, acute inflammation, stress, infarction, oncology.
• Neutrophils decreased — viral infections, fungal diseases, some medications, immunodeficiency states.
• Lymphocytes increased — viral infections, tuberculosis, lymphocytic leukemia, hyperthyroidism.
• Lymphocytes decreased — acute bacterial infections, immunodeficiencies, prolonged stress, corticosteroid treatment.
• Monocytes increased — chronic infections (tuberculosis, syphilis), autoimmune processes, leukemia.
• Monocytes decreased — immunodeficiency, stress, toxic effects.
• Eosinophils increased — allergies, parasitic infections, skin diseases, leukemia.
• Eosinophils decreased — acute infections, stress, trauma, childbirth.
• Basophils increased — allergies, chronic myelogenous leukemia, GI tract inflammation, hypothyroidism.
• Basophils decreased — acute infections, stress, hyperthyroidism.
• Platelets increased — inflammation, infections, postoperative period, polycythemia, myeloproliferative diseases.
• Platelets decreased — thrombocytopenia, viral infections, systemic blood diseases, anticoagulant therapy.
• ESR increased — inflammation, infections, anemia, autoimmune diseases, oncology.
• ESR decreased — increased blood viscosity, erythrocytosis, some chronic liver and heart diseases.
