Limitations

The presence of serum precipitins against suspected antigens indicates past exposure sufficient to elicit a humoral immunologic response but not necessarily sufficient to diagnose the disease. Moreover the specific antigen may not be represented in the testing panel. Hence, a positive test does not confirm and a negative test doesnot rule out a diagnosis of HP.
