Is your blood not clotting properly? Let's learn about the Fibrinogen Test!

Do you sometimes have a small wound that doesn't stop bleeding for a long time? Or do you just get bruises and other things? Your doctor may ask you to take a test to check your "Fibrinogen" level. So, today we'll talk about what this Fibrinogen Test is, why it's done, and how it's done.

What is fibrinogen? What does this test measure?

Simply put, fibrinogen is a special type of protein that is produced in our liver. It is the main one that helps our blood clot. Imagine, when you get injured somewhere, the bleeding stops after a while. This fibrinogen helps with that. It forms a blood clot and stops the bleeding.

So, a fibrinogen test measures how much of this protein called fibrinogen is in your blood. It is sometimes called a "Factor I activity test" because fibrinogen is the first factor (Factor I) in the blood clotting process.

Important: If your blood has low levels of fibrinogen, it may have difficulty clotting. This means that even a small wound can cause a lot of bleeding.

When is a fibrinogen test performed?

There are several reasons why your doctor may order this test, especially if you have symptoms that suggest low fibrinogen:

• Do your gums bleed frequently? Not just when you brush your teeth, but also when you just stand there?
• Do you feel like you are bleeding from your digestive system? That is, are there any signs of bleeding from your ``Gastrointestinal (GI) tract``, such as your intestines or stomach?
• Is there blood in the urine or stool? This is definitely something you should tell a doctor about.
• Do you cough up blood?
• Are there just bruises and bruises on the body? If something small hits you and you end up with a big bruise, that should be checked out too.
• Do you often get nosebleeds?
• Have you ever had a condition like a ruptured spleen?

In addition to symptoms like these, there are some other situations that lead to this test:

• If you have had abnormal results from other blood clotting tests, such as a prothrombin time test (PT) or activated partial thromboplastin time (APTT). These tests measure how quickly your blood clots.
• If you have symptoms that suggest you have a blood clotting disorder.
• If you have symptoms of a serious, complicated blood clotting disorder, such as disseminated intravascular coagulation (DIC), which causes small blood clots to form throughout the body, causing bleeding.
• If you think you have genetic diseases that affect blood clotting.
• If you have recurrent pregnancy loss , sometimes problems with fibrinogen can also be the cause.

What are the types of Fibrinogen Deficiency?

A fibrinogen test can tell if you have a fibrinogen deficiency, or a lack of fibrinogen. Some of these deficiencies are genetic . That is, they are caused by a change in the genes (gene mutation). Sometimes these are hereditary , meaning they are passed down from parents to children.

There are three main types of fibrinogen deficiency:

1. Afibrinogenemia: This is when there is no fibrinogen in your blood at all. This is a very, very rare condition. It affects about one in a million people.

2. Hypofibrinogenemia: This means that your blood has very low levels of fibrinogen . Although not as rare as afibrinogenemia, this is also not very common. However, it is slightly more common than afibrinogenemia.

3. Dysfibrinogenemia: This is when your blood has normal levels of fibrinogen, but it doesn't work properly. This means that the protein fibrinogen is present, but it can't help your blood clot. Since many people with this condition don't show symptoms, it's hard to know exactly how many people have it. However, it's also more common than afibrinogenemia.

How to prepare for a fibrinogen test?

In most cases, you don't need to do anything special to prepare for this test. Your doctor will advise you on this.

However, if you are taking blood thinners , your doctor may tell you to stop taking them a few days before the test. You should do this exactly as your doctor tells you.

Another little thing, drinking plenty of water is good not only for this test, but before any blood test. When the body is well hydrated, it is easier to draw blood from the veins.

What happens during the test?

This is a very simple blood test. You have nothing to worry about. Here's what happens:

1. Usually, a small area around the elbow of your hand is thoroughly cleaned with a cotton swab dipped in rubbing alcohol.

2. Then, a nurse or doctor will very carefully insert a small needle into your vein. It will feel like a small ant being bitten, that's all.

3. A small tube (bottle) is connected to that needle and some blood is collected.

4. After the blood is drawn, the needle is removed and a piece of clean gauze is placed over the area and pressure is applied.

That's it! The job is done in a few minutes.

What happens after the test?

After donating blood, you can go home straight away. You can continue with your normal activities as usual. There is no need to rest particularly.

Are there any risks with this test?

In fact, the fibrinogen test is a very safe test. The risks are very low.

You may feel a little blue or a little sore where the needle was inserted. This will go away on its own in a day or two. Don't worry about it.

What do the test results say?

This test measures fibrinogen levels in either grams per liter (g/L) or milligrams per deciliter (mg/dL).

A normal healthy person's fibrinogen level should be between 2 and 4 grams per liter (2-4 g/L) or 200 to 400 milligrams per deciliter (200-400 mg/dL).

Whether your fibrinogen level is higher or lower than this normal range, it can indicate a condition. For example:

• Having blood clotting disorders .
• Fibrinogen deficiency (meaning there is not enough fibrinogen).
• A condition called irregular fibrinolysis . This means that there is an abnormality in the process of dissolving and removing unwanted blood clots that form in the body.

What if I have fibrinogen deficiency?

If your test results confirm that you have fibrinogen deficiency, your doctor will prescribe the necessary treatment to increase your fibrinogen levels.

Most often, a blood product containing fibrinogen is given to you through an intravenous (IV) line. Fibrinogen is usually given this way every other day until your fibrinogen level returns to normal.

Also, your doctor may give you fibrinogen in this way during special times when you are at risk of excessive bleeding . For example:

• After a major injury or accident.
• Before an operation.
• Right when the baby is born, right after the baby is born.

Your doctor will decide on these treatments based on your condition.

Finally, take-home message:

Okay, so we've talked a lot about the Fibrinogen Test. To summarize:

• A fibrinogen test measures the level of a protein called fibrinogen in your blood, which helps blood clot.
• This protein is produced in our liver.
• A doctor will order this test if you have symptoms that suggest a blood clotting problem , such as frequent bleeding, difficulty stopping bleeding, or frequent bruising .
• This is a simple blood test. There is usually no special preparation required.
• If your fibrinogen level is low, there is treatment for it. Your doctor will provide you with the most appropriate treatment.

So, if you have these symptoms, don't be afraid to see a doctor and get advice. With tests like these, you can quickly find out if there is a problem and start treatment. Then you can recover quickly without waiting for a big problem.
