Hi, thanks for writing to HCM. There are no blood tests to confirm buergers disease. It can be diagnosed only by performing Angiogram (arteriogram) using a dye which helps to delineate any blockage in the arteries. A simple clinical test - ALLENS TEST will also help in assessing the blood flow through the arteries of the involved hand. There is no treatment to cure buergers disease but the only effective way to halt the disease progression is to quit smoking. There are many treatment options (though less effective) that can be tried * Medications to dilate blood vessels, improve blood flow or dissolve blood clots * Intermittent compression of the arms and legs to increase blood flow to your extremities * Spinal cord stimulation * Surgery to cut the nerves to the affected area (surgical sympathectomy) to control pain and increase blood flow, although this procedure is controversial * Medications to stimulate growth of new blood vessels (therapeutic angiogenesis), an approach that is considered experimental by many * Amputation, if infection or gangrene occurs Hope this information is helpful. Good day
