Routine laboratory tests are not indicated for the diagnosis of asthma but may be used to exclude other causes of wheeze. Elevated eosinophil count and elevated serum IgE levels may be observed in patients with a repeated history of allergic trigger. Arterial blood gas and pulse oximetry may be used to assess the disease severity and response to therapy.
