The Monkeypox virus A29L antigen is a surface protein linked to the monkeypox virus (Mpox), a zoonotic virus that can spread from animals to humans and among people. Detecting the A29L antigen in a sample signifies an active infection, as antigens are usually found during the early symptomatic stage of the disease.
It is a viral surface protein involved in the structure of the monkeypox virus and serves as a biomarker to detect an active Mpox infection.
A positive result means that monkeypox virus proteins have been detected in the sample, indicating an active or recent infection.
Yes, since antigens are generally detectable soon after symptoms begin, A29L antigen testing can identify infection during the early, contagious stage.
Antigen testing identifies the virus itself (current infection), while antibody tests detect the body’s immune response (past or ongoing infection).
