What we do
The Serology Laboratory at the Colorado Department of Public Health and Environment (CDPHE) analyzes blood specimens for diseases of public health significance, including vaccine-preventable diseases, diseases transmitted from animals to humans, and mosquito-borne diseases. 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 health care providers determine whether the infection occurred recently or years ago.
- The State Lab tests for blood-borne pathogens, including HIV, syphilis, and hepatitis A.
- The State Lab analyzes tissue specimens from animals suspected of exposing humans to rabies and plague.
- The State Lab offers West Nile virus serology testing. Testing fees may be waived for serology testing as determined by our statewide public health surveillance program.
