Coagulation tests (coag, PT, PTT, platelet count) are tests to evaluate your pet’s ability to form a normal blood clot. Coagulation tests are recommended as a part of a medical work-up if surgery or a non-surgical biopsy is planned, or if your pet has demonstrated a bleeding tendency.
Coagulation tests are done after a small amount of blood is drawn from a vein and the blood is evaluated on an in-house analyzer for immediate results.
Normal coagulation tests do not guarantee that your pet will not have a bleeding problem during a procedure. The tests are used to evaluate the risk of significant bleeding and determine the need for transfusions prior to, during or after a procedure.
