[|Human|] I went to the ER with a feeling of chest heaviness and could not get a deep breath. Nuclear stress test was fine, cardiac echo was fine, VQ scan showed a low probility of PE, D-dimer was elevated at 250 and segs were elevated at 60.8. what do the elevated labs represent if anything
[|AI|]  Hi thanks for contacting Chat Doctor ... Noted your D dimer level elevated.... It signifies coagulation abnormality like disseminated intravascular coagulation like condition or pulmonary embolism in which fibrin degraded product present in blood . Your symptoms highly suggestive pulmonary embolism.... Examination of your calf muscle done to look for deep vein thrombosis ... Here for confirmation of pulmonary embolism CT angiogram can be done.... If embolic seen heparin given..... So search for cause need to be done as otherwise d dimer not elevated Also investigate with PT, apt like test .... Consult good physician for detail examination and investigation ... Take care.
