Routine laboratory blood work is generally not helpful in the diagnosis of noninfectious bursitis. In cases of septic bursitis, however, the leukocyte count and erythrocyte sedimentation rate (ESR) may be mildly to moderately elevated. Blood cultures may be drawn if infection of deep bursae is a concern. ESR, antinuclear antibody (ANA), rheumatoid factor (RF), and anti–citric citrullinated peptide (anti-CCP) tests should all be ordered in cases where autoimmune disease is suspected because these inflammatory disorders can trigger bursitis.
