What does an INR of 9 mean?

Abstract. An international normalized ratio (INR) higher than 9 is associated with a high risk of bleeding, yet most studies have focused on outpatients with lower INR.

What can happen if INR is too high?

The higher your PT or INR, the longer your blood takes to clot. An elevated PT or INR means your blood is taking longer to clot than your healthcare provider believes is healthy for you. When your PT or INR is too high, you have an increased risk of bleeding.

What happens if INR is too low?

If your INR is too low, you could be at risk for a blood clot – but if it’s too high, you could experience bleeding.

What is the formula to calculate INR?

The INR uses the ISI to equate all thromboplastins to the reference thromboplastin through the following equation: INR = (patient PT/mean normal PT) ISI. Thus, the INR can be calculated using the working prothrombin time ratio once the ISI of the thromboplastin is known.

What can cause an increased INR?
