A complete blood count (CBC)  with differential may show increased white blood cells, particularly eosinophils. In<unk><unk>  eosinophilia is generally mild to moderate, usually 5-20%. On the other hand, in certain types of pulmonary eosinophilia, higher percentages are reported. For example, in drug-induced eosinophilia, eosinophils may account for as much as 40% of the WBCs. Generally, the result of stool examination is negative at the time of the<unk><unk>  presentation. Nevertheless, parasites and ova can be found in the stool 6-12 weeks after the initial parasitic infection. Pulmonary symptoms usually have been resolved when parasitic forms are found in the stool. Immunoglobulin E (IgE) level might be elevated. A bronchoscopy with bronchoalveolar lavage may show increased eosinophilic count. Sputum analysis or gastric lavage may occasionally show larvae of Ascaris or the other parasites with pulmonary cycle.
