Rapid, non-invasive detection of antibodies or antigens to support diagnosis, staging and immune-status assessment of infectious diseases.
Serology detects the immune response to infection — or the pathogen's antigens directly — enabling diagnosis of diseases that are difficult to culture or amplify, screening of blood donations, epidemiological surveillance and vaccine-response assessment.
When the immune system meets a pathogen it produces antibodies: IgM appears early (recent/acute infection), followed by IgG (past exposure, chronic infection or immunity); IgA contributes at mucosal sites. Antigen tests instead detect components of the pathogen itself, indicating active infection.
ELISA is the workhorse for detecting antibodies or antigens with high sensitivity and specificity. Western blot confirms positive screening results (classically for HIV). Rapid tests deliver point-of-care answers. Immunofluorescence assays detect antibodies using fluorescence microscopy.
ID Labs offers rapid, non-invasive serological testing that aids early diagnosis, monitoring of infection progression and assessment of immune status across viral, bacterial, fungal and parasitic infections.
