Do you have a problem with your blood clotting? Let's talk about these Coagulation Studies!

Have you ever had a small cut that didn't stop bleeding for a long time? Or, have you ever had a bruise that turned blue without any damage to your body? You might think, "This is normal." But, these are signs that there may be a problem with your body's blood clotting process. It's at times like these that doctors recommend a blood test called 'Coagulation Studies.' So, let's talk about this simply and politely today.

What exactly is this blood clotting?

Think about what happens when you get a cut somewhere on your body. After a while, the bleeding stops. Then a small blood clot forms on top of the wound and dries up. This is the blood clot that we all know.

Simply put, this is a wonderful defense mechanism in our body. There are several special proteins floating in our blood, which are produced by the liver. We call these clotting factors . When there is damage to a blood vessel, such as a wound, these proteins and platelets come together and form a dam, closing off the damaged area. This is how the bleeding stops.

This process needs to be very balanced.

• If the factors are reduced: If these proteins (factors) are reduced, it takes longer for blood to clot. This means that even a small wound will not stop bleeding .
• If these factors increase: If these factors increase unnecessarily, blood clots can form in the blood vessels . This is also a dangerous condition.

After the wound heals, our body gradually dissolves and removes the blood clot . This process is called ``Fibrinolysis``.

What are the main tests for Coagulation Studies?

There are several tests that can be done under this. Your doctor will recommend the necessary tests based on your symptoms. Here are the main ones.

While these tests can identify a problem with blood clotting, they cannot predict how severe bleeding will occur in the future. However, once the cause is identified, appropriate treatment can be initiated.

In what situations are these tests performed?

Obviously, these tests are done if there is bleeding that cannot be stopped or if there is just bleeding. But there are several other reasons besides that.

• Bruising easily: If you frequently get bruises on your body for no reason.
• Bleeding that is not consistent with the wound: If there is excessive bleeding even from a small wound.
• Swelling and pain for an unknown reason: Sometimes these symptoms can be caused by bleeding inside the joints.
• Liver Disease: Since blood clotting factors are made in the liver, these tests help monitor the status of someone with liver disease.
• Vitamin K deficiency: Vitamin K is essential for blood clotting. These tests are also done to check for a deficiency.
• When taking blood thinners: If you are taking a blood thinner like Warfarin, your doctor will often do these tests (especially the PT test) to see how much the medicine has affected your body.
• Before surgery: Before major surgery, these tests are performed to ensure that the patient's blood clotting is normal.

How to understand the test report?

When you receive your test report, your doctor will explain the values ​​to you. Usually, if the “activity” on the report is normal, it means that your blood clotting process is normal.

• Low activity: You are more likely to bleed.
• High activity: You are more likely to develop unwanted blood clots.

Sometimes, this condition can be temporary. For example, it can be caused by a medication you are taking or a vitamin deficiency. In such cases, treating the cause can improve the condition.

Other conditions that reduce blood clotting

Some medical conditions and other causes can also reduce the ability of blood to clot.

• Liver disease
• Cancer
• Venom from a snake bite – In such a case, it is essential to immediately go to the nearest hospital Emergency Department (ETU) . If you need further information about venom, you can also contact the National Poison Information Centre at the Colombo National Hospital .
• Vitamin K deficiency
• Some medications (e.g. Warfarin)
• Blood transfusions

Let's also be aware of hereditary diseases.

Some blood clotting disorders are hereditary. The most common of these are hemophilia A and B. If someone in your family has this condition, you may also be at risk.

Because the disease is inherited through the X chromosome, males are more likely to develop the disease. Women can often be carriers without showing symptoms. This means they have the potential to pass the disease on to their children.
