International Normalised Ratio test is a blood test that measures how long it takes your blood to clot
1 biomarker as listed by Better2Know.
The INR (International Normalised Ratio) test, also called PT (Prothrombin Time), measures the time it takes for your blood to clot. This test is particularly important for people taking blood-thinning medications such as warfarin, or for those at risk of abnormal clotting or bleeding.
The test may be recommended for:
Abnormal INR or PT results may indicate a tendency for blood to clot too slowly or too quickly. Symptoms may include:
A small blood sample is taken and analysed to measure the time it takes for your blood to clot. The result is expressed as an INR value, which standardises clotting times across different laboratories.
Your healthcare provider uses this value to assess your clotting risk and adjust anticoagulant medications if necessary, ensuring your blood is within a safe range.
Your appointment involves a standard blood draw performed by a trained professional. The process is quick and minimally invasive.
Results are typically available within 1 day. You will receive a report showing your INR value and guidance from your healthcare provider regarding any follow-up or medication adjustments.
This is a routine blood test and is very safe. Most people experience only minor discomfort at the needle site.
Occasionally, mild bruising, tenderness, or slight light-headedness may occur. Serious complications are extremely rare. Seek medical advice if you feel unwell after the test.
