The Immunology section of the public health laboratory performs diagnostic and screening tests for syphilis.
Physicians use these results to treat infected patients and to reach out to potentially infected sexual partners to help prevent the spread of the disease. The Immunology section also performs rabies testing. Any animal that bites a human in Philadelphia is tested. Rabies can be fatal to humans if not treated. All cases of human bites must be reported to the Division of Disease Control.
