Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1] Associate Editor(s)-in-Chief: Farnaz Khalighinejad, MD [2]

There are no diagnostic laboratory tests for Takayasu’s arteritis. Testing for acute phase reactants such as the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) may provide additional support for the presence of a systemic inflammatory process; Normochromic normocytic anemia suggestive of the anemia of chronic disease.

 Laboratory abnormalities in patients with TAK are nonspecific and generally reflect an inflammatory process.^[1]

• Acute phase reactants such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) may be elevated. ESR may be > 50 mm/h.
• Normochromic normocytic anemia suggestive of the anemia of chronic disease
• Leukocytosis and/or thrombocytosis
