I am a 28 year old female. I had my 4th child July 27, 2010. 3 days after his birth I was hospitalized for post partum pre-eclymasia and pulminary embolisim. I was tested for everything in the book. All tests came back negative for any genetic blood clotting disease, so the high blood pressure and PE were related to the delivery of my son. My blood was thinned in the hospital with Heparin and I was sent home to give myself lovenox shots and put on cumadin for 6 months. I finished my 6th month treament of coumadin and was taken off of it December 17th 2010. My question is... I had another d'dimer test yesterday and the results were 1.02. I am Rh- ... could my Rh factor have anything to do with a slightly elevated D'dimer result?
