What is a Fibrinogen Degradation Products (FDP) Test?
The FDP test measures small protein fragments released into the blood when the body breaks down clots or the clotting protein fibrinogen. A plasma sample is collected from a vein in your arm using a blue-top sodium citrate tube. Doctors order this test when they suspect a clotting disorder or abnormal clot breakdown. It is also known as the Fibrin Split Products (FSP) test or Fibrin Breakdown Products test.
What Does a Fibrinogen Degradation Products (FDP) Test Measure?
The FDP test detects fragments produced when the body's clot-dissolving system acts on fibrinogen or fibrin. These fragments, known as fragments X, Y, D, and E, indicate that clots are forming and breaking down somewhere in the body.
| Parameter | What it Indicates |
|---|---|
| Fibrinogen/Fibrin Degradation Products (FDP) | Presence and quantity of clot breakdown fragments in the blood |
Why is a Fibrinogen Degradation Products (FDP) Test Done?
A doctor may order this test to investigate unusual bleeding, suspected clotting problems, or certain serious conditions.
Common Symptoms That May Require This Test
The following symptoms commonly lead a doctor to request this test:
- Swelling, pain, tenderness, or warmth in one leg
- Sudden shortness of breath or sharp chest pain
- Rapid heartbeat or coughing up blood
- Bleeding from gums, nose, wounds, or multiple sites
- Easy or severe bruising
- Severe muscle or abdominal pain
- Nausea and vomiting
- Sudden drop in blood pressure
- Unexplained or prolonged bleeding, including heavy periods
- General clotting or bleeding problems
Conditions This Test Can Help Detect
This test can help identify several clotting-related conditions, including:
- Disseminated intravascular coagulation (DIC), a serious condition where tiny clots form throughout the body
- Deep vein thrombosis (DVT), a blood clot in a deep vein, usually in the leg
- Pulmonary embolism (PE), a blood clot in the lungs
- Venous thromboembolism (blood clots forming in veins)
- Severe liver disease, including alcoholic cirrhosis
- Primary fibrinolysis, where the clot-dissolving system is overactive
- Certain cancers, infections, and collagen disorders
Fibrinogen Degradation Products (FDP) Test During Pregnancy
The FDP test can be valuable during pregnancy when abnormal clotting or clot breakdown is suspected. Elevated levels have been associated with complications such as placental abruption (premature separation of the placenta from the uterus) and eclampsia (a severe condition involving high blood pressure). Raised levels have also been noted after intrauterine death and post-partum haemorrhage. This is not a routine prenatal screening test; it is requested only when specific complications are suspected.
Fibrinogen Degradation Products (FDP) Test for Chronic Disease Monitoring
For patients diagnosed with DIC or other clotting disorders, the FDP test may be repeated over time to track how the condition is responding to treatment. It forms part of scoring systems used to diagnose and monitor DIC, alongside other tests such as platelet count and fibrinogen levels. Patients receiving thrombolytic therapy (medicines that dissolve blood clots) may also need periodic monitoring, as this treatment can raise FDP levels.
How to Prepare and What to Expect
The FDP test procedure is straightforward. Here is what you need to know before your appointment.
Do You Need to Fast?
No fasting is required before this test. You can eat and drink normally on the day of your sample collection.
Practical Tips Before Your Test
A few simple steps will help ensure an accurate result:
- Bring a detailed clinical history, including your symptoms, previous test results, and relevant medical records, as this is required for the test.
- Tell your doctor about all medicines you are currently taking, especially blood thinners such as heparin, barbiturates (sedatives), or thrombolytic agents like streptokinase and urokinase, as these can affect your results.
- Do not stop any medication without consulting your doctor first.
- Drink enough water before your test to make the blood draw easier.
- Wear clothing with sleeves that roll up easily.
Step-by-Step Procedure
The sample collection for this test follows these steps:
- A trained phlebotomist (a professional who draws blood) cleans a small area on your inner arm with an antiseptic.
- A small blood sample of approximately 3 ml is drawn from a vein, usually at the bend of your elbow.
- The sample is collected into a sky-blue-top tube containing sodium citrate, which prevents the blood from clotting during transport.
- The tube is gently inverted several times to mix the blood and anticoagulant thoroughly.
- The sample is labelled, stored at refrigeration temperature (2 to 8°C), and dispatched to the laboratory for analysis.
- The plasma is tested using a manual method to measure the level of fibrinogen degradation products present.
Factors That Can Affect Accuracy
Certain factors may influence your FDP test results:
- Underfilled sample tubes can lead to inaccurate readings due to an incorrect blood-to-anticoagulant ratio
- Traumatic blood draws, recent surgery, or severe physical trauma can raise FDP levels
- Menstruation may be associated with slightly increased FDP values
- Medications such as heparin, barbiturates, and thrombolytic agents can elevate results
- Prolonged use of a tourniquet or excessive agitation of the sample can affect accuracy
Understanding Your Fibrinogen Degradation Products (FDP) Test Results
Your results show the concentration of fibrin and fibrinogen breakdown fragments in your blood. A doctor will review these figures alongside your symptoms and medical history.
| FDP Level | Interpretation |
|---|---|
| Less than 10 mcg/mL | Normal; clot-dissolving system is functioning properly |
| Above 10 mcg/mL | Elevated; increased clot breakdown activity in the body |
| Above 40 mcg/mL | Critically elevated FDP levels |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain situations can affect how your results are interpreted:
- Recent surgery, a difficult blood draw, or significant physical trauma can raise FDP levels independently of any clotting disorder.
- Menstruation and the period immediately after childbirth are associated with naturally higher FDP values.
- Labour and delivery, as well as the first week following a normal birth, may produce significantly elevated levels.
- Medicines including heparin, barbiturates, streptokinase, and urokinase are known to increase FDP concentrations.
How to Maintain Healthy Levels
General habits that support healthy circulation and clotting function include:
- Eating a balanced diet with plenty of vegetables, whole grains, and adequate hydration supports cardiovascular health.
- Staying physically active with regular moderate exercise, which promotes healthy blood flow.
- Follow your doctor's guidance regarding any prescribed anticoagulant or clot-related medication.

Frequently Asked Questions
The FDP test is used to evaluate clotting disorders such as disseminated intravascular coagulation (DIC) and venous thromboembolism, which includes deep vein thrombosis and pulmonary embolism. Doctors use the results alongside other tests and clinical findings to reach a diagnosis. It may also be ordered when complications during pregnancy are suspected.
Both tests assess clotting activity in the body. The FDP test measures all fragments produced when fibrinogen or fibrin breaks down, while the D-dimer test specifically measures one particular fragment. D-dimer is often used to rule out DVT or pulmonary embolism, while FDP gives a broader picture of clot breakdown activity.
No fasting is required for this test. You can eat and drink as normal before your appointment. Do inform your doctor about any medicines you are currently taking, as some can influence the results.
Several factors can raise FDP levels without indicating a clotting disorder. These include medications such as heparin, barbiturates, streptokinase, and urokinase. A difficult or traumatic blood draw, recent surgery, and physical trauma can also produce elevated readings. Your doctor will take these factors into account when interpreting results.
The test is not part of routine prenatal screening. However, a doctor may request the FDP test when specific obstetric complications are suspected, such as placental abruption or eclampsia. Results are interpreted carefully during pregnancy, as FDP levels naturally rise during labour and in the postpartum period.
At Lupin Diagnostics, results are typically delivered within 2 days of sample collection. You will receive your report digitally via email or WhatsApp.
