Answer

If the history elicits reports of fever, night sweats, and chills that might suggest other causes for the low back pain, then, at a minimum, obtain a CBC count, erythrocyte sedimentation rate, and urinalysis to rule out cancer or infection. Serum and urine electrophoresis studies may help to rule out multiple myeloma at an early stage when radiographic imaging studies appear negative or inconclusive.
