62 year old man comes into the ER with symptoms of Dyspnea, Tachypnea. History reveals he suffers from COPD. Physical Examination reveals absent tactile fremetius, and expiratory wheezing. Vitals include: RR 25 / min, Temp 103, and HR 99. Blood gases reveals PaO2 72 mm Hg, PaCO2 30 mm Hg.
What lab investigations should be done to confirm the diagnosis:
A) D-Dimer Assay
B) Gram Stain of Sputum Sample
C) Chest X Ray
D) Cardiac Troponin Assay
E) LDH Assay

It is probably a pneumothorax or pleural effusion because of diminished tactile fremitus. I think the best way to proceed would be to do a Chest X Ray.
D-Dimer Assay is a Fibrin Degredation Product (FDP), that is released during fibrinolysis of thrombi. Assay of this product will lead us to this diagnosis.

well mr patel, i think there should b other option on place of d-dimer assay, because from qtn it appears that patient is high risk and symptomatic, so i think there should b other option like ct spiral scan or angiogram (usualy do in high risk patient), and we do d-dimer assay in low risk patient....
Actually, Mr. Amresh, of the options listed above, the best choice is D Dimer Assay. You are right that you could perform a Spiral CT or Angiogram, but of the options listed, that is the best one.
