Hematologic examinations

Platelets

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

Average hemoglobin concentration in the erythrocyte

The mean corpuscular hemoglobin concentration (MCHC) is an indicator of the saturation of erythrocytes with hemoglobin. In hematology analyzers, MCHC is determined automatically. This parameter can also be calculated using the formula: Hb (g/dl)×100/Ht (%).

Average hemoglobin content in the erythrocyte

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

Average erythrocyte volume

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

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

Hematocrit

Hematocrit is the volume fraction of red blood cells in whole blood (the ratio of the volumes of red blood cells and plasma). The value of hematocrit depends on the number and volume of red blood cells.

Hemoglobin

Hemoglobin is the main component of red blood cells and is a complex protein consisting of heme and globin. The main function of hemoglobin is to transport oxygen from the lungs to the tissues, as well as to remove carbon dioxide from the body and regulate acid-base balance.

General blood test

The concept of a “general clinical blood test” includes determining the concentration of hemoglobin, counting the number of red blood cells, color index, white blood cells, erythrocyte sedimentation rate (ESR) and white blood cell count.
