If a patient has an INR of 1.2 are they clotting slower or faster? i know that a normal INR is 2.0 to 3.0 but i cannot find ANYWHERE where it says what is faster or slower clotting times.
My last resort was to ask someone on here, thanks!
A normal INR is 1.0 because it's a measurement of the patient's prothrombin time compared to the prothrombin time of a normal sample of blood.
Patients on warfarin will have a target INR which is often 2.0 to 3.0 but can be different depending on the reason they're on warfarin. So, if the target INR is 2.0 to 3.0 and the patient's INR is below 2.0 that means their warfarin dose needs to be increased. If the patient's INR is above 3.0 that means their warfarin dose needs to be decreased.
The higher the INR the greater the risk for bleeding/haemorrhage, I think from memory above 4.0 is considered significant risk. This is why people on warfarin have regular INRs done and their warfarin dose is adjusted according to the result.
To answer your question, a patient with an INR of 1.2 has close enough to normal clotting time.
Enoxaprin is administered to thin the blood to prevent clots, or prevent dislodging a clot that already exists. You would administer the dose because you want to increase clotting time (and therefore increase the INR). 1.2 to is close to normal, and therefore would not be considered therapeutic. The dose may need to be increased to achieve a therapeutic level.
