Blood clotting is one of the extremely important physiological processes in the normal human body, in case the body is damaged and leads to bleeding. The blood clot test will help check the ability of blood to clot for timely treatment.

1. How important is blood clotting?


Coagulation, hemostasis, simply understood, is the change in the physical state of the blood, changing it from liquid to solid and fibrin in order to protect the damaged area of ​​the vessel wall and prevent blood from flowing out. out of the blood vessels, out of the body, and at the same time maintain the state of blood circulation in the human body.
It is necessary to have a combination of 3 factors including: blood cells, vessel walls, and plasma proteins to form the clotting process. In particular, the clotting process is directed and regulated by humoral and neurological factors.
Any imbalance in the coagulation and anticoagulation processes has the potential to cause embolism or bleeding. Therefore, in the body there is always a balance between the blood clotting system and the anti-clotting system. Coagulation disorder is a fairly common disease that patients may experience when the body has a deficiency of clotting factors, making the blood unable to clot as normal and the patient can now face the risk of death. died from excessive blood loss. On the contrary, in case the body has a deficiency of clotting inhibitors, it will lead to thrombosis due to blood clots, they do not dissolve and interfere with blood circulation.

2. What is a blood clot test?

The process of forming blood fibrils in the body is also known as coagulation, when the body encounters damage that leads to bleeding, the blood fibers will contract and form a clot. The amount of Fibrinogen, platelets, hematocrit and a number of other factors will play a role in determining the degree of contraction of the blood clot.
Principle of blood clots: When blood leaves the vessel wall, it will clot due to the formation of fibrin fibers. The fibrin network will hug the visible components and then contract to form a clot that separates from the serum.

3. Perform blood clot contraction test

The process of performing the blood clot test will go through the following steps:
Step 1: Prepare the means
37 degree Celsius water bath, clean test tube size 75 x 9.5mm Antiseptic alcohol cotton, pump plastic needle Step 2: Technical procedure
The technician will take venous blood and distribute it into 2 glass tubes (1.5 - 2ml) coated with physiological saline. Place the glass tube containing the blood in the water bath at 37 degrees C. After about 2-4 hours, the results will be read.

Step 3: Read the test results for blood clots
Blood clots completely shrink: Create a clear border clot, the serum part accounts for about 50-65% of the total blood volume and no free red blood cells. Blood clot nearly complete contraction: Formation of blood clot and the serum fraction accounts for about 30-50%. Incomplete clot coagulation: Clot formation and serum fraction accounts for about <30%. Non-coagulating clot: Does not form a separate part of the serum. Broken clot: Formation of clot with unclear margins and most of the free red blood cells in the serum.
