Diagnosis of diseases. Biochemical blood test: what will it show?

Since ancient times, the person was interested in how the organism is arranged, why various diseases are overcome. Find out the cause of the disease was very difficult, and sometimes only an autopsy answered, but it was too late. At that time, they could not even imagine how easy it would be to look inside a person without autopsy and make a diagnosis. Progressive development of mankind has moved so far that it is enough to pass a blood test to determine the disease. Next, we'll look at how the diagnosis is currently performed and how much we can tell the biochemical blood test.

What is Diagnosis?

Diagnosis of the disease is primarily the collection of detailed information, as well as various examination methods, thanks to which the doctor makes an accurate diagnosis, and as a result, a productive treatment is appointed.

Diagnosis begins with the examination of the patient. Further blood tests, urine tests are prescribed. In the development of the latest technology, the following diagnostic methods have become popular:

• X-ray examination.
• MRI and CT.
• Ultrasound.

Depending on the patient's complaints, the optimal diagnosis is chosen, or even a combination of several methods.

The first point in the diagnosis after examining the patient is a general blood test, but often prescribed and a biochemical blood test. What he will show, will affect the further examination and treatment.

Who needs this blood test?

Such a test may be prescribed by a doctor to any patient. It shows the presence of a hidden pathology, it helps to find out which system has failed. Also, the doctor prescribes biochemistry to exercise control over the treatment. The expert himself decides which data of the indicators require verification.

There are diseases in which the first thing is prescribed a biochemical blood test. What he will show, will affect the course of treatment. This is most often important for such conditions:

• Diseases of the blood.
• Kidney disease.
• Violation of the endocrine system.
• Diseases of the cardiovascular system.
• Disturbances in the work of the digestive tract.
• Pathology in the functioning of the musculoskeletal system.
• Problems in the work of the liver.

What does the biochemical blood test show?

This analysis consists of a large number of indicators that allow you to assess the performance of the body and its condition as a whole. It provides an opportunity to track the functioning of the following organs and body systems:

• Assess the level of metabolism in the body.
• Identify the lack or excess of trace elements.
• Functioning of the liver.
• Gallbladder.
• The kidneys.
• Pancreas.

It is this analysis that makes it possible to recognize the disease at an early stage, to reveal its hidden causes, and also to prevent many problems. Correctly explain the biochemical analysis of blood (which he shows) can only a doctor. Do not draw conclusions yourself.

How to donate blood to biochemistry

For analysis on biochemistry, blood is taken from the peripheral vein. The most popular place of blood sampling is at the level of the elbow. If, as a result of a trauma or for some other reason, there is no way to take blood in this area, you can take it from another place.

It is necessary to fulfill several conditions before passing a biochemical blood test. What he will show, how true the results will be, depends on your actions.

1. Blood surrenders to an empty stomach.
2. After the last meal must pass at least 8 hours, drink drinks, which contain sugar, before the analysis can not.
3. At least 2 days before the test should not drink drinks that contain alcohol. Also, do not eat too fatty foods.
4. Before you go to the laboratory, it is better not to engage in increased physical work and not be nervous.
5. Biochemical analysis is given before any other diagnostics and treatment.
6. Taking medications can distort the results of the analysis, so it's better to abstain.

How to decipher a blood test

After the blood sampling procedure is completed, the result will be given out after a while. Indicators will be in the column next to the norm. However, to analyze, the biochemical blood test that shows, can only the attending physician. Probably, for statement of more exact diagnosis to you additional methods of diagnostics will be appointed.

Consider what indicators are indicated in the analysis and whether they can reveal such terrible diseases as cancer, HIV or hepatitis.

What indicators of analysis are important

Undoubtedly, everything that the biochemical analysis of blood from a vein shows is important, but we will consider those indicators that are most often determined for the diagnosis.

• Total protein. Comparing these indicators, you can determine in what state the internal organs and blood. With increased protein, infectious diseases and oncological diseases can develop. Also, it rises when vomiting, diarrhea. With low indications, liver disease, various bleeding, thyrotoxicosis are possible. Low rates will be with fasting.
• Bilirubin. This indicator helps diagnose liver diseases, bile ducts, and also shows anemia. Elevated bilirubin indices can talk about various hepatitis, anemia or neoplasm in the liver or cirrhosis.
• Enzymes. Their number and activity give information about the condition of internal organs. With excessive activity, it is possible to develop hepatitis, pathologies in the heart muscle, hypoxia, hemolysis, pulmonary embolism.
• The level of glucose. A very important indicator for those already suffering from diabetes. Not less important for controlling sugar levels. If the indicator is underestimated, there may be an endocrine disease or impaired liver function.
• Cholesterol level. High numbers of cholesterol indicate the development of arteriosclerosis of blood vessels. Increased risk of cardiovascular disease. Especially dangerous is the increase in "bad" cholesterol.
• Amylase. The increase of this enzyme indicates the presence of an inflammatory process in the pancreas.
• Urea. High indicators indicate a poor performance of the excretory system. And also talk about the abuse of alcohol, prolonged starvation, kidney failure, an overdose of diuretics or salicylates.

If you have passed a biochemical blood test, what he will show, how to proceed, only the attending physician can establish.

Often, patients are concerned about whether biochemical analysis can show cancer, or hepatitis, or HIV infection. Let us consider this further.

Indicators of oncological diseases in the blood

Oncology is one of the serious diseases. Will the biochemical analysis of blood show cancer? Of course, in such patients the blood counts will differ significantly from others, but it is impossible to say with 100% certainty, because additional methods of examination are needed to confirm the diagnosis.

Looking at the blood test of an oncological patient, we will see the following deviations:

• Increase in leukocytes.
• ESR increased.
• Low level of hemoglobin.

As a result of the progression of cancer cells, the body secretes specific antigen-proteins. Due to the determination of precisely such antigens, it is possible to determine in which organ there is a beginning oncological process. These antigens are called oncomarkers.

Popular oncologists are:

• PSA is a condition of the prostate.
• CA125 - the state of the ovaries of the endometrium.
• CA 15-3 - the condition of the mammary glands.
• CA 19-9 - the state of the gastrointestinal tract.
• CEA - the condition of the liver, lungs, pancreas, bladder, intestine.

If a biochemical blood test shows cancer, it can be confirmed only by donating blood to oncomarkers and conducting additional diagnostics.

Biochemistry in hepatitis

No less dangerous disease is hepatitis. In the process of diagnosing this disease, a biochemical blood test is required. He will show hepatitis with an increase in the following indicators:

• Significant increase in enzymes ALT AST.
• Increase in direct and total bilirubin.
• Increase in triglycerides.
• Increase in gamma globulins.
• Reduction of albumins.

In addition, immunological analyzes and histological examination of blood by PCR are performed.

HIV infection and biochemical blood test

The virus of immunodeficiency, getting into the human body, weakens its immune system. In this case, the body becomes more susceptible to infections and cancer. In HIV-infected people, blood counts will show anemia, leukopenia and thrombocytopenia. Biochemistry of the blood is examined in order to see violations in the work of the kidneys, liver, glucose level.

However, it can not be said that a biochemical blood test will show HIV. He will indicate changes in the work of the body, the deviations that have arisen. To determine HIV there is a special test that detects antibodies to the ELISA virus. The PCR method is also used, which allows to detect this pathology on the tenth day after infection.

Biochemical analysis in childhood

If we compare what the biochemical analysis of blood shows in a child and an adult, the difference consists only in the norms of the norm. It is worth remembering that the children's body is growing and the norms differ for different age categories. By assigning a biochemical blood test to a child, the doctor only wants to confirm his fears or dispel.

When taking blood, the same rules should be followed as for adults, one difference is that it depends on the parents.

Remember: the correct preparation before passing the analysis will get a more accurate result. The diagnosis can not be made, relying only on the biochemical blood test. A comprehensive survey will provide accurate answers to all the questions posed.
