Overview
A complete blood count (CBC) with differential may show increased white blood cells, particularly eosinophils. In Loeffler syndrome 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 Loeffler syndrome 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.
Laboratory Findings
- CBC diff
- A complete blood count (CBC) with differential may show increased white blood cells, particularly eosinophils.
- In Loeffler syndrome 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.
- Stool exam
- Generally the result of stool examination is negative at the time of the Loeffler syndrome 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.
- Bronchoscopy and bronchoalveolar lavage
- A bronchoscopy with bronchoalveolar lavage may show increased eosinophilic count.
- Sputum analysis or gastric lavage
- Sputum analysis or gastric lavage may occasionally show Larvae of Ascaris or the other parasites with pulmonary cycle.
