Blood clot tests to know

Blood clot tests are used to assess and diagnose bleeding problems. In addition, this test is used for monitoring on people using warfarin or other anti-blood clots. There are various blood transfusion tests, the choice of which one depends on the circumstances and the suspected problems.

1. Blood clot tests

1.1 Blood formula tests

The blood count test is a routine test, which is used to count the number of red blood cells, white blood cells and tingers in each ml of blood. This test may show that the number of tinglets in the blood is low or high if any.

1.2 Bleeding time test

This test is performed by injecting a needle into the earlobe or arm so that the blood flows naturally and measures the time from the moment the blood starts to stop flowing. The normal duration of the blood clot process is 3-8 minutes.

1.3 Mere coaalysis tests

Blood samples after being taken into the test tube containing anti-freezing substances will be taken for laboratory analysis. Multiple tests such as PT tests or APTT tests can be performed to check the activity of blood clot factors.

These tests are carried out by measuring the duration of blood clot formation after the addition of some activated substances to the blood sample. If the duration of blood clot formation is longer than a normal blood sample, it means that one or more blood clot factors are low or not in the sample. Depending on the blood clot factor that wants to be determined, the tests are different because they differ only in the composition of chemical substances added to the blood sample.

1.4 Antiamatulation monitoring tests

If taking the drug too much can cause bleeding problems, using the drug in too little dosage can increase the risk of the formation of blood clots

If taking the drug too much can cause bleeding problems, using the drug in too little dosage can increase the risk of the formation of blood clots. Therefore, it is necessary to check the monitoring of the use of anti-freezing drugs.

Inr testing is the type of test used to monitor drug dosages (usually warfarin) for users. The INR index is calculated using PT testing. Your doctor or nurse will set a 'target' INR level for you, depending on the reason for using the drug. By regular blood checks, your doctor can help you adjust the dose of the drug to achieve this 'target' INR level.

1.5 Testing for specific blood clot factors

The number of multiple blood clot factors can be determined by several different techniques. When your usual blood clot test shows a problem with blood clots, one or more tests of this type are required. For example, this test is used to determine the number of factor VIII in haemophiliA blood samples (for people with HaemophiliA, this factor is very low or absent).

1.6 Test for tinglet a condensation

This test is used to measure the speed and extent of precipitation (atsevere) tingers after the addition of a chemical substance that promotes a condensation to a blood sample. The test has a role to test the function of the tinglet.

1.7 Blood test for prone blood

If a blood clot is detected in a normal blood vessel, you may need to perform several tests to determine the cause. For example, a blood test examines the 'V Leiden factor', an abnormal change in factor V – making blood clots easier to form.

1.8 Other tests

There are many other conditions that can affect blood clots such as vitamin deficiency, leukemia, disorders in the liver, or infections. Therefore, in addition to the blood clot test it is necessary to do other tests to find out what causes the abnormal number of tinglets or of blood clot factors.

2. When to take a blood clot test?

Clients can be consulted to perform blood clot tests in the following cases:

  • Suspected bleeding disorders.
  • Suffers from a number of liver diseases that can affect the process of formation and destruction of blood clot elements.
  • To assess the risk of bleeding before surgery.
  • Blood clots appear in blood vessels for no apparent reason.
  • Using anti-blood clots such as warfarin (to check if the dosage reaches the target).
