Hello, I am a 52yr old female. Average height and weight. I have had a total hysterectomy in 2006. I by chance had a d dimer ran about a year ago now and it was at 900. Thinking this was maybe this was my normal. They checked it again in a couple of weeks and it was 1,200 then 1,800, then 2,200 and as of yesterday it is 2,656. I have been to see Oncologist who ran multiple tests including CT of chest and US of legs. US was negative. CT shows two lung nodules and I will have another CT next month. I also have a positive ANA with an RNP antibody of greater than 8. I was sent to a Rheumatologist for this and that apt was a joke. He told me I didn t have Lupus and that was it. I am very concerned that I have a blood clot forming somewhere in my body that will break off and either give me a stroke, heart attack or aneurism. Any thoughts on why my d dimer is increasing. Any advise or response would be greatly appreciated. I do work in a lab and have been informed that it may be a blood clot. I have back pain and seem to catch myself breathing at a rapid rate without exertion. Please advise. Thank you.
