What is the normal INR level without Warfarin therapy?

  1. 1

  2. 2

  3. 2.5

  4. 3.5

The correct answer is: 1

INR (International Normalized Ratio) is a measure of how long it takes for your blood to clot. Normal INR levels range from 0.8 to 1.2. This means that if your blood takes 1-2 times longer than average to clot, your INR level is within the normal range. The options B (2), C (2.5), and D (3.5) are all higher than the normal range. This indicates that your blood is taking longer than average to clot, which can be dangerous and increase your risk for bleeding. Option A (1) is the only answer that falls within the normal INR range, making it the correct answer.
