Description
Why It’s Done:
• To monitor patients taking blood-thinning medications (such as warfarin)
• To evaluate unexplained bleeding or easy bruising
• To diagnose clotting disorders or liver disease
• To check clotting function before surgery or other invasive procedures
• To assess the effects of medications that affect blood clotting
Preparation:
• No special preparation is usually needed unless specified by your doctor.
• Inform your healthcare provider about all medications and supplements you are taking, especially blood thinners, aspirin, or herbal remedies, as they can affect the results.
• Avoid alcohol before the test, as it can interfere with clotting.
• Follow any specific instructions regarding medication adjustments if your doctor advises.
