Serology Laboratory

 
 
The Serology lab analyzes blood specimens for diseases of public health significance. A serology blood test is performed to detect and measure the levels of antibodies as a result of exposure to a particular bacteria or virus. When people are exposed to bacteria or viruses (antigens), their body’s immune system produces specific antibodies against the organism. Antibody levels (antibody titer) help physicians determine whether infection occurred recently or years ago.
 
What we do
We test for blood-borne pathogens, including HIV and hepatitis B, and analyze blood specimens for diseases of public health significance, e.g., vaccine-preventable diseases, diseases transmitted from animals to humans and mosquito-borne diseases.
 
We also help investigate disease outbreaks significant to public health and analyze tissue specimens from animals suspected of exposing humans to rabies and plague. 
 
We offer West Nile virus serology testing. Testing fees may be waived for serology testing as determined by our statewide public health surveillance program.
