To determine the coagulation time of blood, contact your local doctor and get a referral for laboratory studies. Before any kind of surgery, if you suspect a violation of coagulability of the blood of all patients sent for this analysis.
In the lab you will perform the analysis on coagulability non-stabilized blood by the method of Lee and white. To take from Vienna to the first tube 1 ml of blood, then the second and third alternately take the same amount of venous blood. All tubes will put in a water bath and every 30 seconds will tilt at an angle of 70 degrees. The complete coagulation time was spotted on the stopwatch. Normal summing the rate of clotting of blood in each vial is 8 to 12 minutes.
When variations of this technique the coagulation time of the blood is determined at room temperature without using the water bath. Tubes with venous blood plug with rubber stoppers and constantly turn up and down. While considered normal indicators when summarized by calculating 12-16 minutes.
Micromethod is used in cases when the patient due to various reasons it is impossible to obtain a sufficient quantity of venous blood, therefore, take 0.2 ml, placed in a vial and check the coagulation at a temperature of 37 degrees without stirring. Considered normal results of clotting within 5 minutes.
Micromethod based on the same three test tubes, which are alternately placed in 1 ml of venous blood. The coagulation time at room temperature is 4 minutes, 55 seconds to 11 minutes, 55 seconds – these indicators are considered to be normal. The test has lower accuracy than the classical method of Lee and white, but nevertheless, used to this day.
Definition of coagulability of the blood according to the method of Burker based on analysis of blood from a finger. The coagulation time of the blood in healthy patients equal to 5-6 minutes.
Blood clotting (coagulation, gemostaziogramma) a necessary stage in the study of blood clotting in situations where the patient expects some loss of blood. Indications for use blood test for clotting Analysis can reveal insufficient or, conversely, surplus the ability of the blood to clot.
Analysis of blood clotting (coagulation laboratory) is a very important study of the actual condition of blood clotting. In our medical center for a more accurate diagnosis and with the aim of obtaining enhanced values of blood parameters You can analyze PETIT (foreign analogue – blood test INR). Progressive blood of PTI is the definition of prothrombin index, which is the maximum reliability shows the level of coagulation of blood.
Advice 2: How to determine what is clot
With increased blood clotting in the blood vessels of the body can form blood clots or thrombus, s, which can lead to a lethal outcome in isolation from the vessel. This usually happens instantly, so you need to be able to recognize the symptoms of a blood clot, to prevent the development of thromboembolism.
A healthy human body operates at two opposing systems of blood – clotting and anticoercive. Under normal balance they thin the blood, preventing the formation of blood clots – however, with the predominance of the coagulation system in the blood vessels begins to form a clot. Initially, the blood clots are small plaques that increase over time and with a weak attachment to the vessel wall can break away from her, "poplaw" with the flow of blood through the arteries and veins.
When injected into the most narrow place of the blood flow, the clot completely blocks it, which leads to thromboembolism and bleeding to a certain organ. So, at the clot of the blood vessels of the brain in humans is ischemic stroke, a blood clot in the heart arteries – heart attack, when a blood clot leg vein thrombosis. The most severe form of this disease is pulmonary thromboembolism, which can be determined by chest pain, acute heart failure, asphyxiation and virtually instant death. It trombley pulmonary artery doctors explain 20% of sudden deaths.
Symptoms, which can determine the presence or removal of a blood clot, are directly linked to its localization in a particular organ. First and foremost, you need to be wary when unexplained heaviness in the leg muscles, constant swelling, pain and cyanosis of the skin – these events often accompany a venous thrombosis. If clots of arteries of the abdominal cavity, the person may be noted abdominal pain, diarrhea and vomiting.
With a suspected blood clot you need to visit a GP, who will refer the patient to relevant specialists. To determine this diagnosis is ultrasound, vascular angiography, venography of the veins, and assigned a number of blood clotting and cholesterol. To avoid blood clots, you need to have an active way of life, to enter into the diet more plant food, drink more fluids, do not expose themselves to traumatic situations and carefully monitor blood pressure.
The cause of the clot can be inflammatory, neoplastic or traumatic factors of inner vascular surfaces.
As accurately determine the presence of a blood clot without medical diagnosis is difficult, the presence of the above symptoms is a loud signal about the need to visit a doctor.
