RECOMMENDATION: Essential laboratory tests include serum C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), white blood cell (WBC) count, blood cultures, synovial fluid analysis and culture of tissue and/or synovial fluid. Further molecular testing and leucocyte esterase (LE) testing may have a role and warrant further research. Imaging studies include ultrasound in the hip joint. Symptoms lasting over a week warrant investigation with plain radiography. Magnetic resonance imaging (MRI) and bone scanning may have value in confirmation of the diagnosis in some patients.
