I am new to this forum. I have not been diagnosed with APS but I have been suffering from many symptoms ( serious brain fog, memory problems, constant tinnitus in both ears) that might look like APS. all the doctors that i have seen say they have no idea what it is and just keep prescribing anti-depressants that don't work. I just wanted to ask, if I had APS would my INR be lower than the normal range (0.8-1.2)? I have taken INR test few times and in all cases it came back normal. Just curious if it is possible to APS with normal INR results. Thanks a lot.
