How is vasculitis diagnosed?
The diagnosis of vasculitis is based on a person's medical history, current symptoms, complete physical examination, and the results of specialized laboratory tests. A doctor can test for blood abnormalities, which can occur when vasculitis is present. These abnormalities include:
- Anemia (low red blood cell count)
- A high white blood cell count
- A high platelet count
- Signs of kidney or liver problems
Blood tests also can identify immune complexes or antibodies (ways the body fights off what it thinks is a threat) that can be associated with vasculitis. Additional tests may include X-rays, tissue biopsies, blood vessel and heart scans.
