It's most likely a hemophillia problem associated with a decrease in clotting factor Vii. Which I haven't heard much of just Hemophillia due to factors Viii and iX.

The INR has basically replaced the prothrombin time, or PT.
PT/PTT and INR

Absolutely not! Stop whatever anticoagulants you are on immediately.
Acetaminophen can increase the results of your INR, meaning your blood would be thinner. You should consult with your physician regarding Tylenol usage as the frequency of testing your PT/INR may need to be increased. However, Tylenol generally has a limited effect on INR's. Consuming the maximum dosage of 4g (4000mg) generally effects the INR very little.
