Morphology

• The test material is blood.
• The patient does not need to be fasting.About 30 minutes before the test, it is advisable to drink a glass of water or bitter(unsweetened) tea.

The test does not require being fasted, but eating a meal before the test can affect the result, so it is advisable to perform the test 1-2 hours after taking the last meal. The day before the test, intense physical exercise is not recommended, which can also have an effect on the test result.

Peripheral blood morphology consists of qualitative
and quantitative evaluation of blood morphotic elements and includes:
- Determine the number of morphotic elements, i.e.: red blood cells (erythrocytes), white blood cells (leukocytes) and platelets (thrombocytes),
- calculation of the values of color indices.

The red blood cell system includes:
- RBC - the number of red blood cells (erythrocytes). Erythrocytes, thanks to the hemoglobin they contain, are oxygen carriers. Increased amounts of RBCs are referred to as hyperemia (redness, erythrocytosis, polyglobulia), and decreased amounts are referred to as anemia, or anemia.
- HGB - hemoglobin concentration
- HCT - hematocrit, or the ratio of red blood cell volume to plasma. It is an important parameter on which the viscosity of the blood depends.
- MCV - mean volume of the red blood cell. Depending on the MPV value, we divide red blood cells into microcytic (MCV below normal), normocytic (MCV in the normal range) and macrocytic (MCV above normal). The size of the blood cell gives us information about the cause of anemia.
- MCH - the average weight of hemoglobin in a blood cell
- MCHC - average concentration of hemoglobin in a blood cell
- RWD - a measure of variation in erythrocyte size

The white blood cell system includes:
- WBC- total number of white blood cells (leukocytes). The function of leukocytes is to protect the body from microorganisms. An increase in the value of WBC, or leukocytosis, can be caused by physiological factors, for example: in newborns, during pregnancy and the postpartum period, after physical exertion, as a result of stress, pain, overheating of the body or excessive cooling. A decrease in WBC values is leukopenia, which can be caused by viral infections (influenza, measles, rubella, chickenpox), severe bacterial infections (tuberculosis, typhoid fever), systemic connective tissue diseases (so-called collagenoses), vitamin B12 deficiency, folic acid deficiency, damage to the bone marrow by drugs.

Under normal conditions, we distinguish between 5 types of white blood cells, given as the so-called expanded blood formula, i.e. the number of each type of blood cell per unit volume, viz:
- neutrophilic granulocytes (neutrophils),
- acidophilic granulocytes (eosinophils),
- basophilic granulocytes (basophils),
- lymphocytes,
- monocytes.

The platelet-forming system includes:
- PLT - platelet count,
- PCT - platelet count,
- MPV - average platelet volume,
- PDV - platelet anisocytosis index, i.e. what % of platelets deviate in volume from the average,
- PLCR - percentage of large platelets.

The test is performed by the following methods: impedance, fluorescence flow cytometry, spectrophotometry, enumeration from data obtained from direct measurements,SLS.
Ordering the test implies consent to perform it by these test methods.
