While no tests can confirm whether you have Buerger's disease, your doctor will likely order tests to rule out other more common conditions or confirm suspicion of Buerger's disease brought on by your signs and symptoms. Tests may include:
Blood tests to look for certain substances can rule out other conditions that may cause similar signs and symptoms. For instance, blood tests can help rule out scleroderma, lupus, blood-clotting disorders and diabetes, along with other diseases and conditions.
The Allen's test
Your doctor may perform a simple test called the Allen's test to check blood flow through the arteries carrying blood to your hands. In the Allen's test, you make a tight fist, which forces the blood out of your hand. Your doctor presses on the arteries at each side of your wrist to slow the flow of blood back into your hand, making your hand lose its normal color. Next, you open your hand and your doctor releases the pressure on one artery, then the other. How quickly the color returns to your hand may give a general indication about the health of your arteries. Slow blood flow into your hand may indicate a problem, such as Buerger's disease.
An angiogram, also called an arteriogram, helps to see the condition of your arteries. A special dye is injected into an artery, after which you undergo X-rays or other imaging tests. The dye helps to delineate any artery blockages that show up on the images. Your doctor may order angiograms of both your arms and your legs — even if you don't have signs and symptoms of Buerger's disease in all of your limbs. Buerger's disease almost always affects more than one limb, so even though you may not have signs and symptoms in your other limbs, this test may detect early signs of vessel damage.
