What do blood coagulation tests indicate?

Coagulation tests measure your bleeding ability and clotting time. Coagulation tests can help your doctor assess your risk of excessive bleeding or the formation of a blood clot (thrombus) somewhere in a blood vessel.

Coagulation disorders can cause bleeding, blood loss or very dangerous blood clotting. If your doctor suspects you have a clotting disorder, they may recommend one or more blood clotting tests. These tests measure different proteins and how they work.
Conditions that can cause blood clotting problems include:
Liver disease ; Thrombotic disease - excessive blood clotting; Hemophilia. Coagulation tests are useful in monitoring patients who are taking medications that affect blood clotting. Coagulation tests are also sometimes used before surgery.

Commonly used clotting tests are:
Complete blood count (CBC): Your doctor may order a complete blood count (CBC). The results of this test may indicate that you have anemia or a low platelet count, which can interfere with your blood's ability to clot. Factor V test: This test measures factor V, a substance involved in blood clotting. Low factor V can be a sign of liver disease, primary fibrinolysis (breaking up of a blood clot), or disseminated intravascular coagulation (DIC). Fibrinogen levels: Fibrinogen is a protein made by your liver. Abnormal fibrinogen results can be a sign of excessive bleeding or bleeding, fibrinolysis, or placental abruption (where the placenta separates from the uterine wall). Prothrombin time (PT or PT-INR): Prothrombin is another protein your liver produces. A prothrombin time (PT) test measures how well and how long your blood clots. It may take longer if you are taking anticoagulants. Other reasons for abnormal results include hemophilia, liver disease, and malabsorption. It is also useful in monitoring people taking medications that affect blood clotting, such as warfarin (Coumadin). Results are given in the number of seconds it takes for the blood to clot. Platelet count: You may have an abnormally low count if you are having chemotherapy, taking certain medications, or have had a large blood transfusion. Other causes of low platelet counts include celiac disease, vitamin K deficiency, and leukemia. Anemia, primary thrombocythemia, or chronic myeloid leukemia (CML) may be the cause of an abnormally high platelet count. Thrombin Time: Thrombin time measures how active fibrinogen is. Abnormal test results can be caused by inherited fibrinogen disorders, liver disease, cancer, and taking medications that affect blood clotting. Bleeding time: This test analyzes how quickly small blood vessels in the skin close and stop bleeding.

Coagulation index tests are conducted in the same way as most routine blood tests. You may need to stop taking certain medications before having your blood drawn, and no other preparations are needed.
The technician will disinfect a spot on the back of your hand or the inside of your elbow. They will insert a needle into a vein to draw blood. The side effects of coagulation tests are generally very minor. You may have mild pain or bruising at the site of the blood draw. Risks include dizziness, pain, and infection.
In a nutshell, a coagulation test measures your ability to stop bleeding and how long it takes for your blood to clot. Coagulation tests can help your doctor assess your risk of excessive bleeding or the formation of a blood clot (thrombus) somewhere in a blood vessel, and it is also sometimes used before surgery.
