Are laboratory tests typically required for diagnosing trochanteric bursitis?

• A. Yes, they are always required.
• B. No, they are never helpful.
• C. No, they are not routinely required unless infection or systemic disease is suspected.
• D. They are required to confirm the diagnosis in all cases.

Answer: (C)

Laboratory tests are not routinely required to diagnose trochanteric bursitis. The diagnosis is primarily clinical, based on lateral hip pain and focal tenderness over the greater trochanter with pain on movements that irritate the bursa. Imaging or ultrasound can help rule out other causes or guide injections, but routine labs usually don’t change management in an uncomplicated case.

Labs are appropriate only if there are signs suggesting infection or systemic inflammatory disease, such as fever, warmth or redness of the area that raises septic bursitis concern, or a known inflammatory condition. In that context, inflammatory markers (ESR/CRP), white blood cell count, and possibly synovial fluid analysis if bursitis is aspirated, become informative. Therefore, laboratory tests are not routinely required; they’re indicated when infection or systemic disease is suspected.
