blood test

In a blood test, blood test or blood test, information from extracted blood is obtained by various laboratory tests. Since blood is the essence of our lives, it contains a wealth of information that allows conclusions to be drawn about your state of health.

What is a blood test?

In a blood test, blood test or blood test, information from extracted blood is obtained by various laboratory tests.

The blood tests can be carried out not only on whole blood, but also on serum or blood plasma. In spite of the many different possibilities of examination, a blood sample is usually sufficient, as most tests can be carried out with only 2 ml of blood.

On the basis of a blood test, it is also possible to draw conclusions about the condition of individual organs. This succeeds on the basis of certain proteins, the so-called enzymes, which are in the blood and whose existence provides information about the state of health of the respective organ.

However, many other tests can be performed as part of a blood test. Therefore, a distinction is made first in a small and a large blood picture.

Function, effect & goals

As part of the small blood picture, the values ​​of the platelets, also known as platelets, the white blood cells, called leukocytes, and the red blood cells, the erythrocytes, examined.

Furthermore, the concentration of hemoglobin is examined. This type of blood test allows conclusions about the general health of the patient. It can also be determined from these values ​​whether the patient has a weakened immune system, inflammation in the body, deficiency symptoms or problems with blood clotting.

If a large blood picture is taken during a blood test, this serves for a more detailed breakdown of the information in the small blood picture. By counting or taking a blood smear, the shape of the red blood cells and the percentage of different types of blood cells can be determined.

In the area of ​​the organs, a blood test using certain enzymes can provide information about the state of health of the heart, bile, liver, digestive organs, pancreas and muscles.

To detect certain pathogens, such as bacteria or viruses, a blood culture can be created. This is an attempt to propagate the pathogens and thereby identify. This will help the doctor to find the right therapy. This type of blood test for blood poisoning, heart inflammation, unexplained fever or pneumonia can make sense.

If the coagulation property of the blood is to be examined by the blood test, a blood coagulation test is carried out. Here, the consistency of the blood test is examined by different test methods. Blood coagulation tests will be available for upcoming surgeries, susceptibility to thrombosis and to monitoring the use of blood thinning agents.

If the blood test is to determine if there is a source of inflammation in the body, a blood cell lowering rate test can be performed. The speed at which blood cells descend is accelerated or slowed down by various infectious diseases, so that this blood test allows a conclusion on the type of infection.

In a blood test of the blood serum different antibodies can be detected. These again indicate an existing infection. However, since some antibodies remain permanently in the blood, this type of blood test is only conditionally meaningful.

Since the levels of certain hormones in the blood can indicate disturbed functions of certain glands, a blood test can also be carried out with regard to the hormones contained in the blood. However, this study can not only be used to control the endocrine glands, but also allows the identification of a pregnancy and its controlled course.

However, constant values ​​of certain electrically charged particles, such as electrolytes such as potassium, calcium, magnesium, phosphate or sodium, are also important. These are needed to maintain important body functions. Since insufficient levels of the various electrolytes can lead to serious problems such as cardiac arrhythmia, muscle weakness or paralysis, such a blood test is helpful for the root cause of the above-mentioned and many other diseases.

Risks & Dangers

When taking blood for a blood test, it is generally not necessary to expect side effects or dangers. The puncture site is kept as small as possible by the doctor, and immediate subsequent pressure on the puncture site stops further bleeding. However, it is important that blood tests do not jump to conclusions, as many results may indicate different diseases. For this reason, the results should always be checked by different examinations and a thorough history.
