I had a blood clot recently, my d dimer was 2.9, I didn t wan t to take warfarin because of kidney damage so I have been trying to thin blood with nattokinase dmso and magnets, a month later my d dimer was 1.6, the doctor won t give me any more tests as I am not taking perscribed war fearing. I!m assuming another month later my d dimer has reduced further, I am wondering what normal d dimer is, is 1.6 relatively very high. YYYY@YYYY
