Hypersensitivity Pneumonitis Profile
Also known as: Extrinsic Allergic Alveolitis Profile
Use
The test is used to detect the presence of precipitating antibodies associated with hypersensitivity pneumonitis.
Special Instructions
Not provided.
Limitations
Presence of serum precipitins against suspected antigens indicates past exposure sufficient to elicit a humoral immunologic response, but does not confirm the disease or rule it out if absent. The testing panel may not include the specific causative antigen. This means a positive test does not confirm, and a negative test does not exclude, a diagnosis of hypersensitivity pneumonitis.
