Hematologic examinations

Learn how hematologic research testing is performed, how to prepare, and how to interpret results together with a clinician.

Neutrophils: Why are they needed and why do levels change?

Neutrophilic granulocytes are characterized by the presence of two types of granules in the cytoplasm: azurophilic and specific, the contents of which allow these cells to perform their functions.

Leukocyte formula: decoding a complete blood count

The white blood cell count is the percentage of different types of white blood cells in a blood smear. When evaluating the white blood cell count, it is sometimes necessary to consider the absolute counts of individual white blood cell types.

Leukocytes: What the test shows

The white blood cell (WBC) count in circulating blood is an important diagnostic indicator. WBCs are produced in the red bone marrow and lymph nodes.

Platelets: Level and Meaning

Platelets are a formed element of the blood with a diameter of 2-4 µm, representing a “fragment” of the cytoplasm of bone marrow megakaryocytes.

Mean corpuscular hemoglobin concentration: how to interpret the results

The mean corpuscular hemoglobin concentration (MCHC) is a measure of the saturation of red blood cells with hemoglobin. MCHC is determined automatically in hematology analyzers. This parameter can also be calculated using the formula: Hb (g/dL) × 100/Ht (%).

Mean corpuscular hemoglobin: what does this indicator mean?

The mean corpuscular hemoglobin (MCH) characterizes the hemoglobin content in the red blood cell.

Mean corpuscular volume: MCV

The mean corpuscular volume (MCV) is measured in femtoliters (fl) or cubic micrometers. In hematology analyzers, MCV is calculated by dividing the sum of the cellular volumes by the number of red blood cells.

Erythrocytes: functions, norms, causes of deviations

The red blood cell (RBC) count is one of the most important indicators of the blood system. The RBC is the most numerous formed element of the blood, containing hemoglobin.

Hematocrit: a measure of blood viscosity

Hematocrit is the volume fraction of red blood cells in whole blood (the ratio of red blood cell volume to plasma volume). Hematocrit depends on the number and volume of red blood cells.

Hemoglobin: normal values, reasons for decrease and increase

Hemoglobin, the main component of red blood cells, is a complex protein composed of heme and globin. Hemoglobin's primary function is to transport oxygen from the lungs to the tissues, remove carbon dioxide from the body, and regulate acid-base balance.
