We can detect the difference between those with an old exposure (antibodies) and those still contagious (antigen) because they still have active virus present. IgM indicates a new infection at least 3-5 days after incubation. IgG indicates an infection at least 10 days old.
Agile’s dual testing is important to maintain with or without the vaccination protocols while we are challenged with new variants. Agile’s dual testing methodology will permit your operation to continue or re-open safely, while the percentage of people fully vaccinated and boosted increases.
