A member asked:
Why would a d dimer test show a false negative result for clotting? to double check i had an ultrasound that did show dvt on posterior of knee, healthy young male with no known reason for clotting.
A doctor has provided 1 answer
May not be false: If there is no active clotting or dissolution of clotting D-dimer will not be elevated.
