Question: what do abi results mean?
Answer: An ABI ratio of 0.9 or less means you have PAD. An ABI ratio between 0.4 and 0.7 means you have moderate PAD. An ABI ratio less than 0.4 means you have severe PAD. An ABI ratio higher than 1.4 could mean the blood vessels in your limbs are stiff due to advanced age or diabetes.
