Color indicator in the blood test
After blood donation for analysis, in laboratory conditions certain indicators are calculated, which will help the doctor to draw certain conclusions about the patient's state of health. For a person without medical education it is almost impossible to independently understand the leaf with the result of the analysis, too many unfamiliar abbreviations and concepts. But, it will be useful for everyone to find out what some of them mean, for example, blood CPU, or color index. This indicator notifies what the relative content of hemoglobin in the erythrocyte is. In fact, the color indicator of blood is a reflection of the content in the blood cells of the dye, ie, hemoglobin. What is the CPU and how to determine it, we consider in the article.
- Blood color index, what is it?
- Color index reduced
Blood color index, what is it?
CPU carries information about the significant ratios of one of the main blood components, red blood cells and hemoglobin, and also shows the saturation of cells with pigment, with iron content. It is these high-grade blood cells that are responsible for moving oxygen throughout the body.
CP is a calculated value. To determine it, you need to know two quantities: the number of red blood cells( Er) and the level of hemoglobin( Hb).There is a simple formula for calculating the color index:
CPU =( Hb * 3) / the first 3 digits of the value of Er, excluding the comma.
So, for example, if hemoglobin is 150 g / l, and red blood cells in the blood is 5.1 * 1012 / l, then
CP = 3 * 150/510 = 0.882, when rounded, we get an indicator of 0.89.
Measured value in%.
In the sheet with the results of the analysis, another designation of the color indicator of blood is often found - MCHC- is an internationally accepted indicator, meaning the average hemoglobin content in the erythrocyte.to contents ↑
The norm of the color indicator of blood is set the same for adults and children over 3 years old and varies between 0.86-1.15%.For children under three years of age, the acceptable value is considered to be the color index of blood from 0.75 to 0.96%.
This indicator in the blood test is the most important in determining the degree of iron deficiency anemia.
Based on the data obtained in the study, there are three forms of anemia:
- hypochromic( hypochromia), a situation where the color index in the blood test is reduced and is less than 0.85%;
- is normochromic, in this case, the CP is within the normal range, and anemia is associated with internal disorders, for example, in case of renal failure.
- is hyperchromic, when the color indicator of blood is more than the established upper limit of 1.15, occurs when there is a deficiency of folic acid, vitamin B12 in the body, and also polyposis of the stomach or as a result of the appearance of cancer cells.
Of course, each of these forms cannot be a reliable indicator of pathology, therefore, if the color index of blood is significantly increased or decreased, the cause of such a disorder should be sought inside the body, conducting an additional examination.to contents ↑
Color index reduced
Hypochromia, or lower CPU, may indicate impaired synthesis, non-absorption of iron in iron bone marrow normals, or iron deficiency. Low color index can be detected in patients with cirrhosis and malignant neoplasms. Also in practice, other cases are known when blood cells are not fully saturated with hemoglobin, this condition is called microcytosis, the cause may be:
- lead poisoning;
- anemia in carrying a child;
- iron deficiency anemia.
If the color index of blood is reduced in an adult, then first of all it is recommended to pay attention to your daily diet, it should be balanced. The level of hemoglobin is reflected in the state of the whole organism, and in order to constantly maintain it you need to eat a lot of fruits and vegetables, saturated with vitamins A, B, C and E, protein meat and a minimum of fatty foods. With a low CP, doctors often recommend daily drinking red juices and some red wine, it is also better not to drink coffee and completely give up bad habits. This pathology can be eliminated with the help of special medicines, but usually they resort to this extent if the patient needs emergency care and the indicator is critically small. In other cases, the main focus is on proper nutrition, a healthy lifestyle and moderate exercise to maintain the cardio system.
If the color indicator of blood is reduced in a child, then this can speak not only about the development of anemia, but also become a signal in case of kidney failure. Therefore, parents need to be more vigilant, and always on time to pass tests with the slightest symptoms indicating a baby’s indisposition. In the case of low hemoglobin, you need to revise the menu of the child( or mothers in the case of breastfeeding), and do not forget about walks in the fresh air and fortifying gymnastics.
In any form of anemia, a person may have the following symptoms:
- headaches and dizziness;
- weakness, drowsiness;
- paleness of the skin;
- shortness of breath;
Thus, a low color index of blood primarily indicates the presence of anemia in a patient, and an overestimated value may mean thickening of the blood. The cause of both these and other conditions needs to be ascertained and the blood index is brought to a normal value.
God bless you!
