DIAGNOSIS: Thromboangiitis Obliterans is a clinical diagnosis that requires a compatible history, supportive physical findings, and diagnostic vascular abnormalities on imaging studies.
Laboratory testing in patients with suspected Thromboangiitis Obliterans is used to exclude alternative diagnoses.
Lupus anticoagulant and anticardiolipin antibodies are detected in some patients with Thromboangiitis Obliterans but may also indicate an isolated thrombophilia.
