Coagulation tests look at how quickly and how well your blood forms a clot. Clotting has to be balanced: clotting too slowly can cause bleeding, and clotting too quickly can cause unwanted clots. Coagulation tests check how well your blood clots. They are often requested before a procedure or while a person is taking blood-thinning medicines.
Coagulation results are usually given as a time in seconds, or as a ratio, compared with a reference value. Well-known examples in this area are prothrombin time (PT) with INR, and activated partial thromboplastin time (aPTT). Your doctor decides which ones are needed.
They are often ordered before surgery or a dental procedure, when someone bruises or bleeds easily, and regularly for people on certain blood-thinning medicines, where the result helps the doctor adjust the dose.
Tell us if you take any blood-thinning medicine and when you took the last dose. Do not stop or change a medicine unless your doctor tells you to. Coagulation samples need careful timing, so please contact the laboratory before you come.
We confirm the report time when the sample is taken. If your doctor needs the result quickly, mention it on WhatsApp or by phone.
