Routine studies include a CBC, sedimentation rate, chemistry panel, urinalysis, chest x-rays, VDRL test, and tuberculin skin test. Serial blood cultures should be done on all patients. Febrile agglutinins usually should be done. An ASO titer or streptozyme test should be done to exclude rheumatic fever. RNA, ANA, and DNA tests should be done to look for lupus and other connective tissue disease. An HIV antibody titer may need to be ordered.
The next step is to culture any discharge or various body fluids that might be suspect. Thus, a urinalysis and urine culture should be done. A nose and throat culture should be done. A sputum smear and culture may need to be done. The next consideration is to do various serologic tests. A heterophile antibody titer should be done in teenagers. Febrile agglutinin tests may need to be done. Acute and convalescent phase sera for viral studies may need to be done.
Next one should do skin testing. Thus, histoplasmin, coccidioidin, and blastomycin skin testing should be done on patients with a cough. Trichinella skin testing may need to be done, as well as brucellin skin testing. A Kveim test might need to be done for suspected sarcoidosis.
The next step is to do plain x-rays of suspected areas. For instance, x-rays of the teeth may disclose an abscessed tooth. X-rays of the long bones may disclose a metastatic carcinoma.
The next step is contrast x-ray studies of various organ systems. An intravenous pyelogram may show a hypernephroma. A cholecystogram may show gallstones. An upper GI series and barium enema may show chronic pancreatitis or diverticulitis. Angiography may disclose periarteritis nodosa, aortitis or giant cell arteritis.
The next step is to do a CT scan of the abdomen and pelvis. If this is negative, consider a CT scan of the chest and mediastinum. Echocardiography may disclose valvular vegetations or an atrial myxoma.
Next, consider biopsying various organ systems. For instances, a lymph node biopsy may disclose a lymphoma or sarcoidosis. A muscle biopsy may disclose periarteritis nodosa, polymyositis, or trichinella.
Next one should do bone scans and gallium scans for possible metastasis, osteomyelitis, or localized abscesses.
If all these procedures fail to turn up a lesion, then an exploratory laparotomy may need to be done. A fibrin test may indicate Mediterranean fever, or urine for etiocholanolone may also indicate a relapsing type of fever. A urine test for porphobilinogen may diagnose porphyria.
The wisest move is to conduct this investigation with the help of an infectious disease specialist or a specialist in the body organ system most likely suspected of harboring the infection.
