What is the significance of positive influenza A and B with elevated granulocytes in children?

In children, positive influenza A and B with elevated granulocytes is a common immune response involving antibodies that enter the body via the bloodstream. These antibodies primarily participate in antibody-mediated immune responses, helping to defend against and eliminate external pathogens. Their presence can be detected using enzyme-linked immunosorbent assay (ELISA). During specific epidemic seasons, their levels increase in the body, aiding in the diagnosis of pediatric influenza A and B, and serving as an important basis for treatment and control. A test result exceeding 120 cells/μL is generally considered positive, indicating the need for appropriate therapeutic interventions. Additionally, this testing can help identify individuals with chronic infections, facilitating the prevention and control of infectious diseases.
