Spot on: Use of Dried Blood Spots (DBS) for serological immunoassays

Serological immunoassays provide a complementary approach to PCR-based molecular diagnostics in the detection and monitoring of the immune response of individuals exposed to a pathogen. In addition to providing valuable information on the seroprevalence of infection, these tests also provide insight into the development and duration of immunity in convalescent individuals. This information is essential for the development of intervention strategies, which shed light on questions surrounding the spread of the disease and identify individuals at risk of reinfection.
