Do you remember when you fell and sprained your knee while playing as a child? When your mother washed it, applied medicine, and applied a plaster, the bleeding stopped after a while. That's normal. But sometimes, even the smallest wound doesn't stop bleeding for a long time, right? Or some people may just notice that their body is turning blue in places. The reason for things like this could be a lack of a special protein in our blood. Today, we're talking about a very important blood test that many people haven't heard of, but it's something that we're looking into.
Simply put, what is fibrinogen?
Okay, let's put it this way. Fibrinogen is a special type of protein that is produced in our liver. It's like our body's "natural plaster." When you have a cut or a bruise anywhere on your body, this fibrinogen protein rushes in and helps stop the bleeding.
Imagine that when you get a cut somewhere in your body, fibrinogen is like a 'cement' that comes to close the wound. This protein, together with other cells in the blood (platelets), forms a mesh around the wound and closes it. That's when the bleeding stops. We call this process blood clotting . So imagine, what happens if this 'cement' or fibrinogen protein decreases in our blood? Just like you can't build a wall without cement, it becomes difficult to stop bleeding even from a small wound.
In what situations would a doctor recommend this test?
Usually, a doctor does not immediately order this fibrinogen test. It is only when you look at some of the symptoms your body is showing or compare it with other test reports that you become suspicious. Let's see what those symptoms are.
| Symptom | Simple Explanation |
|---|---|
| Frequent bleeding from the gums | If your gums bleed not only when brushing your teeth, but also when you just stand there. |
| Frequent nosebleeds | If you have frequent nosebleeds for no reason. |
| Unexplained bruising on the body | If you don't get hit anywhere, but instead your body turns blue and appears like bruises. |
| Blood in the urine or stool | If your urine is red/dark or you see blood in your stool. |
| Coughing up blood | If blood is mixed with mucus. |
| Bleeding in the digestive system | Symptoms such as stomach pain, vomiting and bleeding. |
In addition to symptoms like these, a doctor may recommend this test for several other reasons.
- Abnormalities in other blood tests: If the results of tests that measure how quickly your blood clots, such as Prothrombin Time (PT) and Activated Partial Thromboplastin Time (APTT) , are abnormal, you may be asked to do this fibrinogen test to find the cause.
- Suspected blood clotting disease: If your doctor suspects that you have a blood clotting disease.
- Severe medical conditions: This test is mandatory in cases of severe medical conditions such as Disseminated Intravascular Coagulation (DIC) .
- Recurrent miscarriages: This may also be included among the tests performed to find the cause for women who have recurrent pregnancy loss.
- Hereditary diseases: If someone in the family has blood clotting problems.
Are there types of fibrinogen deficiency?
Yes. This condition can be divided into three main types. These are usually caused by genetic causes, that is, by hereditary factors.
| Type of Deficiency | Meaning | Commonness |
|---|---|---|
| Afibrinogenemia | Complete absence of fibrinogen protein in the blood. | It is extremely rare, occurring in about one in a million people. |
| Hypofibrinogenemia | Lower than normal levels of fibrinogen in the blood. | It is more common than afibrinogenemia. |
| Dysfibrinogenemia | Even though fibrinogen levels are normal, they are not working properly . | This is also quite common, but it is difficult to detect because many people do not show symptoms. |
How do you prepare for this test?
This is the best part. This test usually doesn't require any special preparation . You don't have to fast or do anything else.
But there's one important thing: If you're taking anything that thins your blood, like blood thinners, you should definitely tell your doctor. He or she will advise you whether or not you should stop taking them for a few days before the test.
Another tip is to drink plenty of water before going for the test. This will make it much easier for the person taking the blood to find your vein and draw blood because your veins will be full.
What happens during the test? Does it hurt?
This is just like having a regular blood test. You have no reason to be afraid.
1. First, a nurse or medical officer will select a suitable vein from your arm, near your elbow.
2. Then clean the area thoroughly with something like alcohol.
3. Next, a small needle is inserted into the vein and the required amount of blood is collected into a small tube.
4. Once the blood is drawn, the needle is removed and a piece of cotton or gauze pad is placed over the area and pressed down.
The entire process takes only a few minutes. There is a slight stinging sensation when the needle is inserted, but it goes away in a few seconds.
Once the test is done, you can go home and continue with your normal activities. There is no problem with that. The area where the needle was inserted may be slightly blue or slightly sore. This will completely go away in a day or two. This is normal.
What does the report mean?
Your blood sample will be tested in a lab and the amount of fibrinogen in it will be measured. Normally, a healthy adult's fibrinogen level should be between 2 and 4 grams per liter (2-4 g/L) or 200 and 400 milligrams per deciliter (200-400 mg/dL) .
If your test result is below this normal range, it could mean:
- You have fibrinogen deficiency.
- Fibrinogen production has decreased due to a liver disease.
- Severe malnutrition.
If the result is higher than normal, it could be due to an infection, cancer, heart disease, or some kind of inflammation in the body.
The most important thing is, don't jump to conclusions based on the numbers in this report. Your doctor is the best person to explain to you the true meaning of your report, why it's there, and what you need to do next.
What to do if fibrinogen is low?
If your test results confirm that your fibrinogen levels are low, your doctor will prescribe the necessary treatment. The treatment will depend on how low your fibrinogen levels are, the nature of your symptoms, and your overall health.
The main treatment is usually to give fibrinogen products through a saline solution (intravenous - IV). This can be given daily or every other day.
This treatment is especially given in cases where there is a high risk of bleeding. For example:
- After a big accident.
- Before a planned surgery.
- When or after having a child.
This treatment can bring the fibrinogen level in your blood back to normal and prevent excessive bleeding.
Take-Home Message
- Fibrinogen is a protein produced in the liver that is essential for the blood clotting process in our body.
- If you have symptoms such as unexplained heavy bleeding, frequent nosebleeds, or unexplained bruising, you should definitely see a doctor.
- The fibrinogen test is a very simple, low-risk blood test. There's no need to be afraid of it.
- Don't panic or self-diagnose after seeing the test results. Always talk to your doctor about it.
- If your fibrinogen level is low, there are effective treatments. Your doctor will recommend the best treatment for you.
