is acceptable.

Heterophile antibodies and rheumatoid factor can cause positive 
interference.

Cross reactions due to closely related antigenic epitopes are seen in 
patients with histoplasmosis, paracoccidioidomycosis, and 
penicilliosis.  Rare cross reactions have been seen in patients with 
aspergillosis and cryptococcosis.
