A drop of blood can tell a lot about a human being. One may use a drop of blood to find out all about a genetic profile or predisposition to various diseases. A drop of blood can provide the psychological profile of a person, indicate the compatibility with a sex partner and predict the duration of life. When scientists examined the human blood under the microscope for the first time, they found out that the blood had the cellular structure. The discovery made it possible to use the blood for diagnostics. The cellular analysis is used for the general, or the hematological blood test.
The complete blood cell count includes:
- the calculation of blood cells – the number of white blood cells, erythrocytes, thrombocytes, etc.
- the differentiation of blood cells, the percentage of the types of blood cells, which allows to see processes taking place in the human body, e.g. the progression of viral infections, the presence of toxic substances, etc.
- the evaluation of the quality of blood cells – the size of the cell and its nucleus, its maturity, the content of hemoglobulin, etc.
There is no diagnosis that could be based on the clinical blood analysis only. The blood plasma/serum analysis develops very quickly in the world today. There are some 1,000 types of blood tests – biochemical, immunochemical, and so on and so forth. Plasma is the molecular mirror of all human organs and tissues; it shows all diseases and infectious processes.
Many types of blood tests are based on the immune response principle. Any bacterium, or any virus, which finds itself in the human body, leaves its trace in the blood in the form of the human immune system reaction to the outside interference. A blood test shows whether the immune system of a particular individual is familiar with a certain pathological agent.
The immune response can be used to find out a great deal of medical parameters, including allergic reactions, predisposition to cancerous diseases, the presence of hormonal irregularities, the development of cardiovascular diseases, abnormalities of the brain tissue and many other factors.
A biochemical analysis may reflect the work of basic internal organs and systems, provide the information about metabolism, or unveil a person’s need in minerals.
People want to use blood test opportunities for their common everyday goals, which do not have any relation to diseases. Entrepreneurs use these hopes and offer various diets based on blood groups.
The clinical blood analysis, a standard biochemical analysis and the urine sample analysis will never be harmful to anyone.
