D-Dimer
A D-dimer test measures small pieces of fibrin, the protein net that holds a blood clot together, which are released as clots break down. It can help your vet look for harmful clots in dogs and cats, and a normal result makes a clot less likely.

What this test checks
- D-dimer, the small pieces of fibrin released when a blood clot is broken down
- Whether clots have been forming and breaking down somewhere in the body
- A clue that, read with other tests, may point to thromboembolism, DIC or some tumours
Benefits of this test
- A normal result makes a harmful blood clot less likely, which helps your vet narrow down the cause.
- Can help your vet decide whether a scan or more clotting tests are needed.
- Adds useful information when DIC, a serious clotting problem, is suspected in a very sick pet.
- Can be tested alongside PT, APTT, fibrinogen and a platelet count for a fuller picture.
When your vet may advise it
- Sudden breathing trouble when your vet suspects a clot in the lungs.
- Sudden weakness, pain or coldness in a leg that may come from a blocked blood vessel.
- Unusual bleeding or bruising in a very sick dog or cat, when DIC is a worry.
- A serious illness that raises clot risk, such as severe infection, pancreatitis, heatstroke or an immune disease that destroys red blood cells.
About this test
When a dog or cat bleeds, the blood forms a clot to plug the leak. A protein called fibrin works like a net that holds the clot together. Later, the body breaks the clot down, and small pieces of fibrin called D-dimers pass into the blood. A D-dimer test measures these pieces. A raised level tells your vet that clots have been forming and breaking down somewhere in the body.
Vets commonly use this test when they are worried about thromboembolism. This means a clot that blocks a blood vessel, for example in the lungs. It is also used when DIC is suspected. DIC (disseminated intravascular coagulation) is a serious problem in which clotting is switched on all over the body. Tiny clots form, and the blood may then fail to clot where it should, so the animal can bleed. Some tumours can also raise D-dimer. The test uses plasma, the liquid part of blood, collected in a special citrate tube that stops the blood from clotting. The tube must be filled to the correct level.
A normal D-dimer makes a harmful clot less likely, which helps your vet narrow down the problem. A raised value is not specific. It can also go up after surgery, an injury, bleeding inside the body or a serious illness. For this reason, vets read it with an examination and other tests, such as the Coagulation Profile (PT, APTT & Fibrinogen), a platelet count or a scan. A registered veterinarian interprets the result together with your pet's signs and history.
How to prepare
Tell your vet about any medicines and any recent surgery, injury or bleeding, and follow the vet's advice about food before the blood sample is taken. The lab confirms the method, sample needs and reporting time when you book.
Reading the result
A registered veterinarian reads the D-dimer result together with your pet's signs, history and other clotting tests. A normal value makes a clot less likely, but no single test can rule one out. A raised value shows clotting activity, not its cause, so your vet may repeat the test, add other tests or advise a scan.

Before you book this test
Why this notice: so you know, before you book, how a test is done, what its limits are and who is responsible.
- Where it is tested. Some tests are done wholly or partly by an independent partner laboratory. The lab tells you before booking if this test is sent out, and the report names the laboratory that did it.
- What a result can and cannot tell you. No test is right every time. A normal result does not rule out every disease, and an abnormal result does not prove one. A registered veterinarian should read the report with the animal’s signs and history before any treatment is started, changed or stopped.
- The sample. A sample that is clotted, too small, wrongly labelled, leaking or too old may be rejected or reported with a note, and the lab may ask for a fresh one.
- Reporting time. Confirmed when you book. Times are estimates, not guarantees, and the lab confirms the time when you book.
- Emergencies. A booking or a pending report must not delay urgent care. If an animal has collapsed, struggles to breathe, has fits or bleeds heavily, call a veterinarian at once.

D-Dimer and Clotting Tests for Bleeding and Clot Risks
Clotting tests check how well a dog's or cat's blood can form a clot, and a D-dimer test looks for signs that clots are forming and breaking down inside the body. Each test answers a different part of the question.
