Can a D Dimer test rule out a PE.

If you are spitting blood you need to go to A and E straightaway. 😲

The d diner is 95 per cent accurate. The hospital would probably have done it when they scanned you etc. It is a simple blood test x 

Hi,

?Yes a D dimer can indicate to a doctor that there is a clot present, although it is not a 100% accurate test, by that I mean other things can also raise it and doctors are mindful of this. 

?My suggestion is to get to an emergency department immediately for treatment if you are coughing up blood and chest pain, they can then do the D dimer blood test and also order a contrast dye CT Scan of the lungs. these tests will tell you in combination, especially the contrast dye CT scan if you definatlely  100%  have a PE. Pulmonary embolisms can be and are fatal if left untreated.

?That's how my PE was found, my left calf muscle was extremely sore, as if I had pulled/strained a muscle, it wasn't sore to the touch but to walk on definitely was, it puffed up, it got really red and hot, I presented to our emergency with my normal angina chest pain, the triage nurse this time was actually more worried about my leg than my chest pain, the tests were done and they found blood clots, multiple, in both lungs, they had broken off and travelled to my lungs, they don't always travel to the lungs, they can get to the heart or the brain, pretty well much anywhere they can lodge themselves in the body.

I have just had a he results of my D Dimer blood test and it’s negative so despite some symptoms similar to blood clots I am confident that I do not have any new clots.
