The expert told what information can be found by blood

Blood is involved in many important processes in our body. It reacts to many pathological processes in the body by changing its composition, so even the simplest laboratory tests help identify abnormalities in the work of various systems and organs. Dmitry Krivosheev, an expert of the educational project on blood and plasma donation "+Ya", told Izvestia on May 15.

For example, he recalled that it is important for residents of the middle zone to monitor the level of vitamin D, which performs many important tasks in the body.

"In particular, it is necessary for the synthesis of sex hormones: progesterone in women and testosterone in men. Due to the lack of this vitamin, the body has problems with the production of these hormones — as a result, reproductive function suffers, the risks of developing obesity and diabetes increase, and mood worsens," explained Krivosheev.

The expert added that DNA, which contains genetic information, can be isolated from blood. According to him, genes largely determine how the body absorbs nutrients or how prone it is to developing certain diseases.

"Let's take breast cancer. Some varieties of this disease are associated with a certain mutation in the DNA, which is inherited — that is, a girl is already born with such a genetic variant. At the same time, the presence of a mutation does not mean that she will necessarily get cancer — it's just useful to know about it, since her risks of getting sick are increased — and it's extremely important not to neglect preventive checkups," said Krivosheev.

On May 14, Kirill Lakhmai, a cardiovascular surgeon at the SM Clinic, told Izvestia about ways to prevent the development of thrombosis. According to him, thrombosis is a natural process that allows the body to protect itself from blood loss. However, he called the formation of blood clots in the veins and arteries a life-threatening factor. The doctor recommended regular blood tests, coagulograms, and coagulation factor tests.
