recent 3 wk off work r/t back injury+ 4hr recent flight. 10days ago in a.m. became +++sob and light headed, midsternal CP-resolved in approx. 3 min. ?PE...will D dimer still be elevated?  is there a point now in testing? (still slightly soboe). I am an ER RN.
Hi, Actually the results of D-Dimer can't be as reliable if 10 days passed. In this case if the overall risk is high CT angiography will be the best option. Hope I could help nourishing you good health In case of further questions don't hesitate to ask
