Coagulation tests in Medellín, Colombia

What do coagulation tests measure?

They assess how well and how fast blood forms a clot. The most common are prothrombin time (PT) with its INR value, partial thromboplastin time (PTT), fibrinogen and platelet count. D-dimer is used when thrombosis is suspected.

When are they ordered?

Before surgery or a procedure, for frequent or hard-to-stop bleeding (nose, gums, heavy periods, bruising), when thrombosis is suspected and in liver disease.

Why are they repeated if I take blood thinners?

People on warfarin need regular INR checks to adjust the dose: too low raises the risk of clots and too high, the risk of bleeding. Newer anticoagulants usually do not require this monitoring.

How should you prepare?

Tell the lab about all medications and supplements you take, especially blood thinners, aspirin and anti-inflammatories. Do not stop any of them without medical advice.
