Serological diagnostic assays are employed by laboratories to determine if an individual has been exposed to a pathogen. This infection could have been very recent (acute) or in the distant past. Our ability to better detect and diagnose infectious diseases is vital to successful vaccination development and treatment efforts. The mission of the Antigen Discovery Team is to develop, through the use of molecular, microbiological, and immunological techniques, cost-effective serological assays that would provide healthcare professionals assays with greater diagnostic sensitivity and specificity over existing tests.
