Norms of general blood analysis and the significance of changes in these norms
Statistics say that as many as 90% of people in the world do not know why we give blood from the finger due to medical tests. A general blood test can give a better insight into a person’s health because virtually every pathological condition is reflected in a change in blood.
Hemoglobin is a protein that transports oxygen from the lungs to the cells of the whole organism. Anemia is a decrease in hemoglobin in the blood. There are several types of anemia, depending on the cause of the anemia. An increase in hemoglobin levels may indicate some diseases of the cardiovascular system, changes with erythrocytes and dehydration of the organism.
Norm for men: 130-160 g / L
Norm for women: 120-140 gr / L.
Erythrocytes – the composition of erythrocytes includes hemoglobin. Decreased numbers are found in anemia and due to metastatic tumors and leukemia. An increase in this indicator can occur due to dehydration, insufficient function of the adrenal cortex and some congenital heart defects.
Norm for men: 4.5 million in 1 μl of blood
Norm for women: 3.9-4.7 million in 1 μl of blood.
It expresses the amount of hemoglobin in one erythrocyte. This indicator is important for determining the type of anemia.
Reticulocytes are “young” erythrocytes. Exceeding the norm is observed in the case of malaria, anemia and an increase in the number of erythrocytes. The reduction indicates poor bone marrow function.
Platelets play an important role in heart coagulation. Falling levels can be caused by the use of some medications, chemical poisoning and various infections. Platelet deficiency occurs in the case of heomlitic disease of the newborn, leukemia, Werlhof’s disease. An increase in the number can occur in the postoperative period and due to injuries, tumors, lack of oxygen and in the case of primary idiopathic thrombocytopenia.
Standard: 180-320x 109 / L.
Leukocytes are immune cells that protect the body from various infections. When the body faces a bacterial infection, the amount of leukocytes increases. The number increases during pregnancy and lactation, during myocardial infarction, allergies, malignant diseases, radiation sickness, taking certain medications and blood diseases. This is characteristic of all types of leukocytes.
Standard: 4-9X 109 / L
Eosinophils and basophils are leukocytes. An increased amount is a sign of allergies, worm infestations and parasites in the stomach.
Norm: 0.5-5% of the total leukocyte count for eosinophils, 0-1% of the total leukocyte count for basophils.
Neutrophils are leukocytes that prevent the penetration of foreign microorganisms. It should not be more than 70% of the total amount of leukocytes at normal values. If the number is increased, it usually indicates an inflammatory purulent process.
Lymphocytes are leukocytes that provide specific immunity, ie they contain infection and produce antibodies to antigens that the body has already encountered. An increased number testifies to infection. Decreased lymphocyte counts are characteristic of HIV infection and some inherited diseases.
Norm: 19-30% of total leukocyte count.
Erythrocyte sedimentation rate or increased speed is the main symptom of inflammatory processes in the body. An increase in indicators for no apparent reason requires an urgent medical examination.
Normal for men: 2-10 mm / h
Norm for women: 2-15 mm / h.
