Blood count results

The results of blood counts provide a lot of valuable information about the state of human health. The blood count determines such parameters as the number of white and red blood cells, thrombocytes and hemoglobin. This type of blood test requires taking a sample of peripheral blood, usually from a vein in the arm. The results of the study show that the circulatory system is functioning properly. A morphological examination is performed at the doctor's request, screening or in the event of disturbing symptoms. The results of the morphology are submitted to the doctor for interpretation.

1. Interpretation of blood count results

A blood test checks parameters such as:

  • erythrocytes

Their normal value is 3.8 M / µL for infants, 3.9–5.6 M / µL for women and 4.5–6.5 M / µL for men. Too many red blood cells is rare. It can be caused, for example, by being high in the mountains. Much more often there are cases of too little red blood cells in the blood. The cause of this condition is anemia resulting from a wide variety of reasons. The most common are excessive menstrual bleeding, pregnancy, blood loss in the course of tumors, gastric or duodenal ulcers, bone marrow and kidney diseases, and iron, vitamin B12 or folic acid deficiency.

  • hemoglobin

Normal hemoglobin results are 6.8–9.3 mmol / L or 11.5–15.5 g / dL for women and 7.4–10.5 mmol / L or 13.5–17.5 g / dL for men. Too low hemoglobin levels indicate anemia, and too high hemoglobin levels may indicate dehydration or problems with the cardio-respiratory system.

  • hematocrit

The norm for this parameter is 35-39% for children under 15, 37-47% for women and 40-51% for men. The reason for a too low result is anemia, and too high dehydration or polycythemia.

  • macrocytosis (MCV), which is the average volume of a red blood cell

The standards are in the range of 80–97 fl. Higher values ​​are not cause for concern, however results greater than 110 fl may be associated with anemia due to folate or vitamin B12 deficiency. Values ​​below the normal range suggest iron deficiency.

  • MCH - average hemoglobin content in the erythrocyte

The correct result is 26–32 pg. This value tells you whether your red blood cells contain the correct amount of hemoglobin. If they do not contain enough of it, it is a sign of hypolouration most often due to iron deficiency.
MCHC - mean concentration of hemoglobin in the red blood cell
The standard for this parameter is 31-36 g / dl or 20-22 mmol / l. Lower values ​​indicate anemia due to iron deficiency.

  • leukocytes

The standard is 4.1-10.9 K / µl (G / l). Higher values ​​occur during infection, inflammation or leukemia, although an excess of leukocytes can also be caused by intense exercise, excess stress, or prolonged sunbathing. Too little leukocyte count may be due to a deficiency of granulocytes, lymphocytes, or both. This happens as a consequence of treatment (e.g. anti-cancer treatment) or bone marrow damage.

  • lymphocytes

Normal values ​​are between 0.6–4.1 K / µL or 20–45%. The cause of higher values ​​may be lymphoma, chronic lymphocytic leukemia, multiple myeloma, childhood infectious diseases or hyperthyroidism. Lower values ​​are recorded in patients with AIDS and people suffering from bacterial infections. Sometimes a lymphocyte deficiency is diagnosed as congenital in children, and then prompt treatment is required. In turn, the norm is a greater number of lymphocytes in children under 4 years of age.

  • monocytes

The correct result for this parameter is 0.1–0.4 G / L. An excess of monocytes may mean: infectious mononucleosis, bacterial or protozoal infections, endocarditis, monocytic leukemia, Crohn's disease, cancer or surgical trauma. Values ​​below the normal range may indicate an infection or be due to certain medications, but monocyte deficiency does not pose a risk to your health.

  • thrombocytes

Values ​​in the range 140–440 K / µl (G / l) are the norm. A greater number of thrombocytes is noted after intense exercise, chronic infections, essential thrombocythemia, iron deficiency, pregnancy or spleen removal. The causes of the thrombocyte deficiency can be painkillers, antibiotics, bacterial toxins, autoimmune diseases, acute leukemia or cancer metastasis.

A morphological examination helps to detect minor health problems such as infections, but it can also become the first step towards the diagnosis of serious diseases such as cancer. Interpretation of morphology results should be based on the standards provided by the laboratory as different facilities use different methods. As a result, the standard ranges may differ between laboratories.
