ERYTHROCYTES (RED BLOOD CELLS) – WHAT EXACTLY ARE THEY AND WHAT ARE THEIR FUNCTIONS?
Erythrocytes, or red blood cells, are blood cells that don’t have a nucleus to don’t require much energy (they obtain it from glucose). They’re about 6-7.5 µm in diameter and a pair of µm thick, resembling a biconcave disk in cross-section. They’re produced within the bone marrow, and therefore, the average survival time is four months. About 2.6 million red blood cells are produced every minute. Their production requires iron (approx. 80%), vitamins B6, B12, C, E, and folate. They owe their red color to the hemoglobin they contain.
The first function of erythrocytes is to move oxygen from the lungs to the tissues mediated by hemoglobin. Hemoglobin combines with oxygen within the alveoli, so it releases it into the tissues. Red blood cells are involved in the transport of CO2 (about 1/3 of dioxide is transferred from the tissues to the lungs within the potassium carbonate style) and play a vital role within the acid-base equilibrium mechanism. If the red blood cells are damaged, the hemoglobin is released from the cells, often called blood hemolysis. Hemolysis usually takes place within the RES of the spleen, where used red blood cells are destroyed.
RED vegetative cell COUNT – WHEN does one must CHECK IT?
In a healthy body, the concentration of erythrocytes within the blood should be at a specific level according to the applicable standards. This can be true when performing blood counts, one of all the necessary diagnostic tests, and may be performed regularly once a year, even in healthy people. An abnormal amount of red blood cells can indicate many diseases. Typically, red vegetative cell testing is usually recommended by GPs when anemia is suspected. The test is additionally helpful in diagnosing cancer and bone marrow diseases. They’re also performed in people with suspected hypoxia. Testing the number of erythrocytes is also useful to anti-doping tests because the amount of red blood cells within the blood increases with doping substances.
WHAT DOES THE RED blood corpuscle TEST LOOK LIKE?
The amount of erythrocytes is set as a part of the blood count, which allows the quantitative and qualitative assessment of the peripheral blood components. It includes the examination of erythrocytes, leukocytes, thrombocytes, blood pigment hemoglobin (HGB), hematocrit (HCT), and parameters associated with red blood cells (MCH, MCV, MCHC, RDW CV ). The test is performed on an empty stomach within the morning (between 7 and 10 am). Don’t drink coffee or smoke before the test. It’s also not recommended to have interaction in physical exercise. A laboratory technician draws blood from a vein within the elbow flexion. It’s not recommended to perform the test in women during menstruation because then the amount of red blood cells decreases, distorting the test results. Cenforce 100 and cenforce 200 best for ed. The amount of erythrocytes is decided after diluting the blood sample with isotonic fluid. Red blood cells are counted (manually under a microscope or automatically) by determining their number during a unit volume of solution. The test also takes under consideration many parameters informing about the condition of erythrocytes, their structure, production, and efficiency, including:
- hemoglobin concentration
- hematocrit, i.e., the proportion ratio of red, white, and platelets to plasma,
- MCH, determining the typical hemoglobin content in erythrocytes,
- MCV, which determines the number of red blood cells (tells you whether or not they are regular, too big, or too small),
- MCHC, which determines the concentration of hemoglobin within the red vegetative cell,
- RDW – erythrocyte differentiation measure coefficient,
- ESR (Biernacki’s reaction, precipitation), informing about inflammation within the body.
WHAT ARE THE NORMS OF RED BLOOD CELLS?
Red blood cells in laboratory results are marked with the symbol RBC (red-blond cells). The norms of red blood cells are :
3.5 – 5.2 million / mm³ for ladies,
4.2 – 5.4 million / mm³ for men,
3.5 – 5.4 million / mm³ for youngsters.
The norm of hemoglobin (HGB, HB) is:
14-18 g / dl in men
12-16 g / dl in women
10-15 g / dL in children.
Hematocrit norm (HT, HCT):
40-54% in men
37-47% in women,
50-70% in newborns,
30-45% in children.
In MCV, the norm is that the same for all age groups and is 82-92 fl (femtoliters), where 1 ft = 1 x 10-15 liters.
Patient morphology results could also be abnormal, which can not necessarily indicate a medical condition. Similarly, works within the conventional range don’t mean that the patient is healthy. Many factors can influence the laboratory values: age, weight, lifestyle, diet, stimulants, drugs, hormonal situation also as equipment, reagents, and research methodology.

Therefore, the interpretation of the results must always be administrated by the attending physician, supported the treatment history, and consequently, the medications are taken.
LOW LEVEL OF ERYTHROCYTES – ERYTHROCYTOPENIA
A low red blood corpuscle count most frequently signals anemia (anemia). Its typical symptoms include weakness, fatigue, sleepiness, decreased concentration, dry skin, pale skin, dizziness and headaches, irregular or rapid heartbeat. Erythrocytopenia also can be caused by other causes, such as:
- deficiency of ingredients necessary for the assembly of red blood cells (iron, vitamin B6, B12, folic acid) or impaired absorption,
- impaired red vegetative cell production (bone marrow diseases),
- shortening the lifetime of red blood cells (defective structure of blood cells, disturbance of the hemoglobin synthesis process, the abnormal immunologic response of the body),
- chronic diseases (kidney diseases, rheumatoid arthritis),
- significant blood loss (gastrointestinal injury or bleeding, internal hemorrhage)
- congenital disabilities,
- overhydration of the body,
- too heavy menstruation,
- bone marrow damage,
- drugs (hydantoin, quinidine, chloramphenicol).
- High level of erythrocytes – erythrocytosis
In turn, elevated erythrocytes may be caused by:
- hypoxia of the body,
- lung diseases,
- congenital heart defect,
- pulmonary heart syndrome
- addiction to nicotine,
