The diagnosis of<unk>  is made by presence of clinical signs and symptoms, eosinophilia, and positive serological findings. Definitive diagnosis of<unk>  is generally made by the detection of larvae in the stool. Sputum examination may rarely be used to identify organisms in cases of hyperinfection. Agar tracking (detection of larval tracks on agar culture plates) has been shown to be more sensitive than the conventional stool examination. However, agar tracking is usually unavailable on a routine basis in clinical microbiology laboratories. Immunodiagnostic tests for<unk>  are indicated when the infection is suspected and the organism cannot be demonstrated by repeated examinations of stool. Enzyme immunoassay (EIA) is currently recommended because of its greater sensitivity (90%). Antibody test results cannot be used to differentiate between the past and current infection. In disseminated cases of<unk> , larvae can be detected in sputum by simple wet-mount in fluid from a bronchoalveolar lavage (BAL).
