need info on lupus anticoagulant process

hi everyone! so around Halloween time in 2024, i, then 22F, had been short of breath for like, a month and a half, before mentioning it to my PCP. i waited so long because i had no idea what was wrong and didn’t know what to do. she had me get a CT of my chest the next morning and i was walked to the emergency room because i had multiple pulmonary embolisms in both of my lungs. i stayed in the hospital for three days on a heparin drip and was sent home on elliquis. fast forward to my hematology appointment and we found out my lupus anticoagulant test came back positive and this test was done before i received any blood thinners in the hospital. so, i was then switched to coumadin and have been on it since about November of 2024.

the only reason we can come up with as for why i ended up with these clots is because i was on birth control for a year before finding them. no other reason has ever come up.

i went to my follow up appointment at hematology and my LA test came back undecided because i am on blood thinners and the doctor said that it’s not safe for me to go off of them to do another test.

does anyone have any advice or information on how to go about any type of lab that would be able to wash blood cells of the blood thinner? because that’s the only way i would be able to get a final verdict on this test.

just thought i would throw this out on here because im not sure what to do at this point:)
