Workup

Laboratory Studies

Obtain bacterial Gram stain and culture from the suspected site of infection.

In a patient who requires hospitalization for suspected infection or in whom a bloodstream infection is suspected, obtain two sets of blood cultures from different sites.

Obtain urinalysis/urine culture in patients with suspected urinary tract infection. The presence of white cells or leukocyte esterase may help to distinguish urinary tract colonization from infection.

CBC count is used to monitor for leukocytosis or a left shift, which indicates infection. A chemistry panel is used to monitor renal function and complications or toxicities associated with antibiotics.

Once an organism has been identified, susceptibility testing is extremely important to narrow therapy.

Imaging Studies

Obtain a chest radiograph to exclude pneumonia in suggestive cases.

Renal ultrasonography is used to assess for urinary tract obstruction or hydronephrosis in patients with recurrent cystitis.
