Diagnosis of Peripheral Artery Disease (PAD)
- Blood tests—Your doctor will review your blood fats and/or your blood sugar. If either is elevated, it may be a treatable cause of PAD.
- Ankle-brachial index—This is a blood pressure recordings in the legs and arms.
- Doppler ultrasonography —This is a small device that can detect blood flow using sound waves. The test is fast, painless, and harmless.
- Angiography —During this procedure, x-rays are taken while dye is being injected into the blood vessels. The x-rays can show blockages. This test is invasive and is usually only done in more serious cases.
- CT angiography—This involves using CT scan technology along with angiography to show the blood vessels.
- MRI scan —Magnetic waves are used to take images of the body.
