RDW in a blood test, what is it, indications for donation

Blood provides metabolism, nutrition and even respiration for all cells and tissues in the body. Doctors always closely monitor its indicators, using tests to determine the presence of certain diseases that destroy the body from the inside without visible symptoms. That is why blood tests are regularly taken: both for preventive purposes and to make a more accurate diagnosis.

One of the most important components of blood are red blood cells or, as they are also called, red cells. They have a disc-shaped, doubly concave shape and perform one of the most important functions in the body - transporting oxygen to cells and carbon dioxide for its removal. Their size is not as important as their volume. In a healthy person, the volume of all red blood cells should be approximately the same, or with slight deviations from the norm; in the case of pathology, different cells appear. To identify such abnormalities, a blood test for RDW is performed.

The abbreviation RDW stands for Red Cells Indicies and translated means “red blood cell distribution width.” This indicator can be found in the results of a general blood test, since a separate study of red blood cells is not carried out. It has two markers:

RDW-CV: shows how much cell size differs from the average (measured as a percentage)
RDW-SD: Reflects the difference in size between the smallest and largest red blood cells (measured in femtoliters).

Indications for testing

Often, such an analysis is preventive and is taken on a regular basis (on average once a year) to identify diseases in the early stages, when they are much faster and easier to treat. It is prescribed to pregnant women to monitor their general condition and identify problems such as anemia, and for inpatient monitoring.

A general blood test is required during hospitalization to conduct a basic examination and obtain a more accurate picture of the disease, as well as before surgery to prevent possible complications. If the body is severely weakened, this may indicate that the person will not survive the operation; in such cases, it is necessary to undergo preliminary treatment for recovery.

The analysis is prescribed to identify and diagnose different types of anemia, as well as for possible diseases of the hematopoietic system. A general blood test helps track dynamics during monitoring of ongoing treatment, accurately determining the onset of improvements or deteriorations in the body’s condition, which helps to timely adjust treatment. It can be prescribed by a physician, general practitioner, surgeon, neurologist and hematologist.

Blood levels

As mentioned above, the RDW indicator has two markers: RDW-CV and RDW-SD, each of which has its own units of measurement and content standards. Next we will look at each of them.

RDW-CV reflects the deviation of red blood cell size from the average, measured as a percentage and has different standards depending on the person’s age.

Children under 6 months: from 14.9 to 18.7%
Children over 6 months: from 11.6 to 14.8%
Adults: 11.5 – 14.5%

RDW-SD shows deviations in the distribution of red blood cells by volume and is measured in femtoliters. The standard deviation is 37 – 54 femtoliters, regardless of age or gender.

Complete blood count with leukocyte count and ESR

Complete blood count is the most widely used laboratory method in clinical practice. It allows you to identify numerous pathological disorders in the body, often plays a key role in making a diagnosis, and may be an indication for prescribing other studies.

Prescribed in case of:

Preventive examination;
Planning hospitalization, invasive interventions, surgical operations;
The presence of anemic symptoms (pallor of the skin, weakness, dizziness, tinnitus, tachycardia);
Diseases of the hematopoietic organs;
Infectious and inflammatory diseases;
Monitoring the effectiveness of treatment.

It includes a large number of different parameters, each of which has its own value both individually and in a comprehensive study.

The leukocyte formula is used in the differential diagnosis of inflammatory aseptic, bacterial, viral, parasitic, and fungal diseases. Usually includes relative values of different types of leukocytes, however, if necessary (determined by the doctor), absolute numbers can be calculated:

Basophils (BASO): above 1% occurs with allergies, hypothyroidism, chronic myeloid leukemia;
Eosinophils (EO): 1-5%. Increased in allergic, parasitic, autoimmune conditions. Decrease in sepsis, abscesses, poisoning;
Neutrophils (NEUT): band-nuclear up to 0-5%, growth in severe inflammatory-infectious pathology. Segmented up to 72%, less than 30% in case of anemia, damage to hematopoiesis due to intoxication, viral invasion, metastases, after chemotherapy;
Lymphocytes (LYMPH) 19-37% . Lower in lymphogranulomatosis, AIDS, after cytostatic and glucocorticoid therapy. Higher in leukemia, toxicosis, drug overdose;
Monocytes (MONO) 3-11%. Growth in bacterial invasion, rheumatoid arthritis. Fall due to immunodeficiency.

ESR (ESR): for men – up to 10 mm/hour, for women – up to 15 mm/hour. One of the markers of acute inflammatory process. It increases with increasing concentrations of immunoglobulins, C-reactive protein, fibrinogen, which is observed during inflammation, intoxication, and progression of malignant tumors.

To correctly interpret the results obtained, it is not enough to know the reference numbers; you need clinical thinking and the ability to comprehensively assess the current medical situation, which only an experienced specialist can help with.

Deviations from the norm (what they talk about)

Before talking about the possible reasons for deviations in this indicator, it is worth noting that it is not specific and cannot serve to accurately determine a particular disease. RDW is analyzed only in conjunction with other data from a general and biochemical blood test. So, if there is a slight deviation from the norm, but other indicators do not cause concern, then, most likely, this simply indicates the characteristics of the body, but to make a more accurate diagnosis, you need to consult a doctor.

An increase in RDW is normal only for newborns under 6 months of age. There is also a slight increase as a result of recent nervous stress and after a blood transfusion, but in all other cases, elevated results indicate the presence of the disease. They may indicate various types of anemia:

Anemia of megaloblastic, myelodysplastic and siderablastic types
Anemia with heterogeneity in red blood cell size (most often due to diet)
Anemia due to impaired myelopoiesis
Anemia due to chronic diseases
Anemia due to acute blood loss (may indicate internal bleeding)
Aplastic anemia

Also, elevated RDW levels may indicate the following diseases:

Some homozygous hemoglobinopathies and homozygous thalassemias
Increased reticulocyte count
Hyperglycemia
Congenital genetic diseases

Reduced indicators do not indicate the presence of any abnormality or disease, therefore such values are not taken into account during the examination. Most likely, this is a variant of the norm.

How the research works

In modern medicine, equipment plays an important role in treatment. the same can be said about a blood test. On an empty stomach, blood is drawn either from a vein in the elbow or from a finger (this method is especially often practiced in the case of children), and then all the work is transferred to a modern analyzer, which conducts research quickly and with high quality, giving an accurate result .
It counts the number of red blood cells of different sizes per microliter of blood, calculates the average cell size and determines the degree of deviation from the norm of this indicator. The largest and smallest cells are also measured and the difference between this spread and the possible norm is analyzed. This indicator is recorded in femtoliters.

Of course, the equipment may not always be accurate; maximum accuracy of results can only be obtained by manual counting, but this is a very long and labor-intensive process, which is practically not used in modern medicine.

If deviations in this indicator occur, the blood test is performed again to obtain a reliable result, because the diagnosis cannot be made as a result of a single blood sample.

Preparation for the procedure

Since taking blood for a general analysis does not imply anything unusual, and the study itself is carried out regularly for almost all people, preparation does not require a person to take any special measures, but no one has canceled the standard recommendations before taking tests so that the results are reliable and correctly reflect the clinical picture:

The RDW test is taken in the morning and on an empty stomach. Dinner in the evening of the previous day before donating blood should be light and at least 8 hours should pass between the last meal and the test, and preferably 12
It is highly not recommended to drink alcohol 2 days before the test, as it can significantly distort the results
It is advisable to give up fatty and fried foods, which have a negative effect on the body, 2 days in advance.
You should not take a blood test after physiological and x-ray procedures
It is recommended to refrain from smoking one hour before blood collection.
It is advisable to exclude any physical and emotional stress; before the analysis, a 15-minute break and complete calm are required.
Particular attention must be paid to the medications you are taking. Almost any medicine can distort the results of a blood test, so before donating blood you need to consult with a specialist: you may have to stop taking the medicine for a while to get an accurate clinical picture, or simply take the drug after the test.

If a repeat blood test is prescribed, it must be taken at the same time (since the composition of the blood may depend on the body’s circadian rhythms) and in the same laboratory. This is due to the fact that units and methods of measurement may vary between laboratories. Only if all recommended measures are followed will the result of the study be correct.

Indications for analysis

Determination of the number of neutrophils is included in the standard of performing a general blood test (CBC). A general blood test is recommended for all people without exception when referred for diagnostic or therapeutic procedures in a clinic or hospital.

Indications for determining the number of neutrophils:

inflammatory diseases of any body system, for example, pneumonia or rheumatism;
surgical inflammatory pathologies – appendicitis, peritonitis;
significant burns to the body surface;
destructive processes in the body, for example, myocardial infarction;
oncological diseases;
infectious pathologies – tuberculosis, measles, diphtheria, etc.;
severe blood loss due to injury or internal bleeding;
poisoning caused by chemicals and toxic substances.

Preparing for a blood test to determine the number of neutrophils

The number of neutrophils is determined during a general blood test. Before donating blood, a person is advised to refrain from drinking alcohol, fried or fatty foods. At least four hours before the procedure, the patient must completely avoid taking any products. Increased physical or psychological stress on the eve of the procedure should be limited.

Norms for the number of neutrophils in children and adults

In the results of a general clinical blood test, neutrophils are designated as NE and measured as a percentage.

from 1 day to 15 days – 31.0%-56.0%;
from 15 days to 1 year – 17.0%-51.0%;
from 1 year to 2 years – 29.0%-54.0%;
