Clinical significance of total blood tests (CBC)

A full blood test is one of the most basic tests aimed at evaluatiing an individual's general health as well as assisting in the diagnosis of clinical conditions. In the results of the analysis, the complete blood formula test provides comprehensive observation, classification and statistics of blood cells circulating in the blood vessels of the body.

1. What is a full blood test?

Although there is no certain shape or structure, blood is still considered an agency and belongs to the system of the paralysed body. The connection of the entire viscera in the body is due to the presence of blood. Indeed, the role of the blood is to bring oxygen gases and nutrients along the flow of arteries supplied to each cell; at the same time, carbon dioxide and products released from intravenous intravenous transformations return to the heart. Not only that, blood cells also take charge of immune function against infectious and blood clot-causing causes, avoiding constant bleeding causing blood loss. In other words, if the blood is sick, other system of muscles will also be difficult without being affected.

The two components that make up the blood are blood cells and plasma. Accordingly, a complete blood formula test is meant to provide information after surveying blood cell types on the characteristics of the number, size, erm of red blood cells, white blood cells and tinglets. In contrast, plasma component tests help measure soluble biomedes circulating in the bloodstream.

2. When to perform a full blood test?

Since this is a basic subclinical, a full blood test is very often in place for the following reasons:

  • Your general health assessment: Even if you don't have any medical conditions, during each routine medical visit, your doctor is prescribed to perform a full blood formula as a mandatory standard of routine medical examination, thereby aiming to monitor your general health and screen for a variety of disorders across blood cell lines , such as anemia or leukemia.
  • Diagnosis of pathology or an abnormal medical condition: When you go to the doctor because of fatigue, weakness, fever, inflammation, bruising or natural bleeding, a full blood formula test can help diagnose the causes of these signs and symptoms. From there, the doctor can diagnose and offer appropriate treatments.
  • Monitor the direction of progress of a pathology: With a complex, unpredictable pathology, blood formula results will be a tool to assist doctors in monitoring diseases, assessing treatment responses, adjusting regimens as well as preventing possible complications.
  • Identify blood transfusion indicators: When the body suffers acute blood loss due to injury, accident, digestive hemorrhage or anemia caused by inability to produce itself in myeloid diseases, blood cancers, you may need to accrete blood at least enough body systems to ensure your function. The most common clinical blood transfusion is the transfusion of alysis, especially when hemorrhagic massively, affecting hemolysis.

3. What is the clinical significance of a full blood test?

The clinical significance of a total blood test in an adult will be analyzed according to each of the following specific blood cell lines:

3.1. Red blood cell line

The red blood cell line contains the most important parameters in the blood formula results because these cells are the most numerous and assume the main function of the blood.

The number of red blood cells, hemolysis and hematocrit are characteristic indicators of the red blood cell line and are closely related. This type of cell regulates the red color of the blood and has the main function of transporting oxygen gas from the lungs to each cell to perform the conversion and receive back carbonic gas to discharge into the lungs. Therefore, if blood is taken in the arteries, the blood will be bright red because it is oxygen-rich blood. On the contrary, if blood is taken in a vein, the blood will be crimson because it is oxygen-poor.

  • Number of red blood cells: Male: 4.35-5.65 trillion cells/L (4.32-5.72 million cells/mcL). Female: 3.92-5.13 trillion cells/L (3.90-5.03 million cells/mcL).
  • Hemolysis: Male: 13.2-16.6 grams/dL (132-166 grams/L). Female: 11.6-15 grams/dL (116-150 grams/L)
  • Hematocrit: Male: 38.3-48.6%. Female: 35.5-44.9%

If one of the above or all three parameters is lower than normal, the person will be diagnosed as anemia. Chronic anemia causes fatigue, body weakness and the most common cause is iron deficiency. Emergency anemia usually occurs due to trauma, gastrointestinal bleeding … The doctor will need further testing to find the cause of anemia and have the appropriate treatment direction.

On the contrary, if the number of red blood cells is higher than usual or both high levels of hemoglobin or hematocrit, this may suggest an underlying medical condition, such as polycything disease or congenital heart disease, chronic lung disease.

3.2. White blood cell line

Unlike red blood cells, white blood cells are consisting of blood cells of no color, almost transparent, so it is difficult to observe under a microscope if chemical staining is not treated. These are cells that participate in the immune system, protecting the body from bacterial penetration.

Number of leukocytes: 3.4-9.6 billion cells/L (3,400 to 9,600 cells/mcL)

If the test result has a higher than normal number of leukocytosis, the person may have become infected or inflamed, the doctor will consider taking antibiotics. However, if the person has absolutely no manifestations of infection at any agency but the leukocytes index is very high, it is necessary to suspect conditions of disorders of the immune system, malignant diseases on blood cells or diseases of the bone marrow. In addition, high white blood cells have been recorded as a result of reactions to certain drugs.

Even so, if the number of leukocytes is low, it is still considered a pathology and should be monitored, such as auto-immune disorders that destroy white blood cells, problems on the bone marrow or cancer. Some drugs can also cause inhibition of leukocycycy production. In these situations, the body will not be able to resist pathogens from the environment due to leukocyetus deficiency. When the infection becomes serious, leukocytic infusion should sometimes also be considered.

3.3. Tinglet cell line

There are huge differences with the red blood cell flow and white blood cell flow, the tinglet is not a real blood cell but a fragment of a very large cell, called a tingular sample. This is a cell located in the bone marrow instead of circulating in the vessel bed like other blood cells. The function of tinglets is to participate in the initial hematoma. When the vessel's vessel city breaks, the tinglets immediately come to adhesion, forming a stopper, which helps the blood to retain in the vessel's heart.

Number of meninges: Male: 135-317 billion/L (135,000 to 317,000 /mcL). Female: 157-371 billion/L (157,000-371,000 /mcL).

Accordingly, if the number of tinglets is lower than normal, the initial hemulation function is no longer guaranteed, you will be at risk of singular bleeding or bleeding that is difficult to detect. Thrombolysis is often a consequence of viral infections, especially dengue. Some drugs can also affect the number as well as the function of tinglets. Therefore, when the patient uses these drugs, a full blood test is also a necessity to monitor the disease. However, long-term tinglet reduction should be suspected of chronic diseases such as cirrhosis, myeloid failure or blood cancer that inhibit the creation of tinglet current.

Conversely, if the number of thrombolytic vessels is higher than usual, usually due to primary disorders during hematoma in the bone marrow, the risk of emboloids, thromboembolysis in the vessels will increase. At this time, patients should consider taking anti-tingering drugs.

In summary, the whole blood test provides a general information about the condition of the blood cells circulating in the vessel. As a result, your doctor can assess your overall health as well as detect a lot of diseases, oriented more tests to determine the diagnosis. Therefore, regular visits and total blood tests are a practical act of health care for you and your loved ones.
