Would DVT show in blood test?
No accurate blood test is available to diagnose deep vein thrombosis. A variety of imaging tests are used to confirm the diagnosis. Doppler ultrasound: Using high-frequency sound waves, this system can visualize the large, proximal veins and detect a clot if one is present.
