What is the CT(Clotting Time) test? 

A clotting time is a time that is required for a sample of blood to coagulate in vitro under standard conditions. There are two methods for evaluating the clotting time, including manual methods such as Lee and White, and Sukharev's capillary tube method. The bleeding time is usually used for patients who have a history of prolonged bleeding after cuts or who have any family history of bleeding disorders.

What are the other names for the CT(Clotting Time) test? 

The other name is the CT test.

What are the test parameters included in the CT(Clotting Time) test?

There is only one parameter.

 

What does a CT(Clotting Time) test measure?

A CT(Clotting Time) test is analysed on a blood sample to find how long it takes for the blood to clot or to coagulate on the slide. An enzyme, thrombin, is produced from the plasma precursor prothrombin to clot blood. Soluble fibrinogen is then converted into insoluble fibrin by thrombin. Therefore, the time it is necessary for blood to clot primarily reflects the time required for thrombin to be generated. This tells your doctor how well your clotting factors are working.

 

What’s the normal range?  

5 - 15  minutes.

Who should get a CT(Clotting Time) test? 

The bleeding time test can be prescribed by the healthcare provider. If the patient is experiencing an issue with blood clotting wherein the blood does not stop flowing after an injury such as a cut or a puncture, then it is suggested to take the bleeding time test to evaluate if the person has problems with blood clotting. If you are undergoing any type of surgery or procedure, a CT(Clotting Time) test is done.

 

Blood clotting disorders' symptoms are delayed blood clotting and longer bleeding time. The bleeding time test is the most common test to check if the blood clotting system has issues that blood is not clotting. This occurs in a very small number of people.  

 

There are a few other tests that are available to evaluate if a person is suffering from bleeding problems. If there is prolonged bleeding in a person, it indicates that the person has an acquired defect in platelet function. Usually, this test is also carried out to determine epistaxis.  

Blood clotting mechanisms in a few people might not function properly, and hence clotting could be difficult.

 

Are there any preparations needed for the CT(Clotting Time) test?

No special preparation is required. Fasting is not required.

What is the cost of a CT(Clotting Time) test?

What is the type of sample required? 

This test requires a blood sample.

Who processes the CT(Clotting Time) test?

A healthcare provider, who is also called a phlebotomist, usually performs blood draws, including those for CT(Clotting Time) tests, but any healthcare provider trained in drawing blood can perform this task. Clotting time will be recorded. The same values will be sent to the labs to generate the reports. 

 

What should I expect during my CT(Clotting Time) test?

You might expect to experience the following during the blood test or a blood draw:

  • You sit comfortably on the chair. 

  • They will disinfect the puncture site with an alcohol swab to minimize the risk of infection.

  • Once the phlebotomist has located a vein, they disinfect the area with an alcohol swab.

  • They will insert the needle into your vein to draw a blood sample. They may feel like a small pinch.

  • After they insert the needle, the required amount of blood will be drawn into a test tube.

  • When they draw enough blood for the test, they’ll remove the needle and hold a cotton ball or gauze on the site to stop any bleeding.

  • They apply a band-aid over the pricked site, and the blood collection is finished.

This process takes less than five minutes.

What should I expect after my CT(Clotting Time) test?

Once, a phlebotomist will note down the clotting time and the same will be sent to the laboratory, where reports will be shared with you.

What are the risks of a CT(Clotting Time) test

Blood tests are done commonly, and they don’t carry any significant risks. You can have a slight pain like an ant bite when the needle gets inserted, and a small bruise may develop there.

When can I expect my CT(Clotting Time) test results?

At Orange Health, bleeding time test reports are available within 6 hours.

What do the results of a CT(Clotting Time) test mean? 

 

Interpretation 

A normal clotting time in a person is between 5 - 15 minutes. By understanding the time taken for blood to clot, it may be determined if the person has a haemophilla for Von Willibrand’s disease.

 

In this kind of defect, the platelets might not be working properly, or the body may be producing too many platelets or fewer platelets. Usually, abnormal results could mean:

 

  • That person has a defect in the blood vessels wherein the blood vessels are unable to transport blood properly throughout the body.

  • A person has a genetic platelet function disorder by birth. This is a genetic disorder that could affect the function of the platelets.  

  • A person could be suffering from thrombocythemia, wherein the person's bone marrow starts producing too many platelets in the body. 

  • A person could be suffering from thrombocytopenia, where the person's bone marrow starts producing a small number of platelets in the body. 

  • A person might be suffering from Von Willebrand's disease. It is a hereditary disease that affects the process of blood coagulation in a person.

 

What are normal CT(Clotting Time) test results?

5 - 15 minutes.

The normal ranges can vary slightly among different laboratories. Some of the labs use different measurements or might do tests on the different samples. Speak to your healthcare provider about the meaning of your specific test results.

 

What other tests might I have along with this test?

Prothrombin Time, Platelet Counts, Von Willebrand
