Coagulation Profile (PT, APTT & Fibrinogen)
A coagulation profile checks how well blood clots by measuring PT, APTT and fibrinogen. It is commonly used before surgery and when a dog or cat bleeds, bruises easily or may have eaten rat poison.

What this test checks
- PT (prothrombin time): how long plasma takes to clot through one part of the clotting chain
- APTT: how long plasma takes to clot through another part of the clotting chain
- Fibrinogen: the protein that forms the mesh of the final clot
When your vet may advise it
- Before surgery or a biopsy when bleeding risk needs checking
- Bleeding from the gums or nose, blood in urine or stool, or bruising without a clear reason
- When a dog or cat may have eaten rat poison
- Liver disease or a serious illness in which clotting may fail
About this test
Clotting depends on a chain of proteins called clotting factors. PT (prothrombin time) and APTT (activated partial thromboplastin time) measure how long plasma takes to clot when different parts of this chain are started in the lab. Fibrinogen is the protein that forms the final clot. A long PT or APTT may point to some rat poisons, liver disease, an inherited clotting disorder or DIC, a serious state where clotting is switched on all over the body. The profile does not count platelets, so a platelet count or CBC is often added. A registered veterinarian looks at all three results with your pet's bleeding signs, medicines and history.
How to prepare
Blood goes into a sodium citrate tube that must be filled exactly to the line, and a clean, gentle draw helps stop the sample from clotting. The lab confirms the method, sample needs and reporting time when you book.

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.

Pre-Anaesthetic Tests for Young and Old Pets
Pre-anaesthetic tests are blood checks done before an operation so the vet can plan the anaesthetic around the pet's own body. Young and old pets raise different questions, and a normal result is not a promise of no risk.

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.

Blood Tubes Explained: EDTA, Serum, Citrate and Fluoride
Blood tubes differ because each holds something different that suits a different test. EDTA is for cell counts, serum for chemistry, citrate for clotting tests and fluoride for blood sugar, so one draw can fill several tubes.
