See the list below:

  • Needle biopsy or aspiration of the joint, possibly with fluoroscopic guidance, can be helpful in identifying the infectious organism. An open biopsy may be necessary, depending on disease extent.

  • Lumbar puncture is indicated when CNS involvement is suspected. Workup of neonatal sepsis should include lumbar puncture, if indicated.

  • Cardiac catheterization may reveal valvular involvement or vegetations.

  • Quantitative cultures from bronchoalveolar lavage obtained by bronchoscopy helps distinguish infection from colonization.

  • Thoracentesis may be indicated for patients who have pleural effusion.
