@sarkarsatarupa No specific laboratory tests confirm or exclude the diagnosis of thromboangiitis obliterans (TAO; also known as Buerger disease).
Arteriographic abnormalities consistent with TAO are sometimes seen in limbs that are not yet clinically involved; therefore, arteriography of all four limbs may be required. Echocardiography and computed tomography (CT) angiography (CTA) should always be performed in patients thought to have TAO in order to exclude a proximal source of thromboemboli or atheroemboli as the cause of distal vessel occlusion.
