Immunodeficient patients are at particular risk of opportunistic infections and are also more susceptible to common pathogens.
An aggressive search for the responsible pathogen may include urine microscopy and culture, blood culture, aspiration of body fluids, endoscopic brushings or biopsies, other tissue or organ biopsies (with lesions on diagnostic imaging); cryptococcal antigen (serum); cytomegalovirus antibodies, Legionella spp antibodies and toxoplasma antibodies.
Consult pathologist for assistance with defining the appropriate testing strategy.See Immunodeficiency, Infection (increased susceptibility)
Faeces - ova, cysts and parasites; examination for microsporidia must be specifically requested.
Faeces - ova, cysts and parasites.See also Worm infection
Faeces - microscopy of fresh specimen; Harada culture for larvae (consult pathologist); Strongyloides sp antibodies.
