Used in diagnostic testing to identify H5N1 avian influenza infection or immune response in individuals with potential exposure to the virus. May be employed in serological testing or rapid antigen detection assays.

The antigen stimulates an immune response in diagnostic tests - either by binding to specific antibodies in patient blood (for antibody detection) or by being detected itself in patient samples (for antigen detection). This allows laboratories to confirm H5N1 infection or prior exposure.

This is a laboratory diagnostic reagent, not a treatment. Should only be handled by trained laboratory personnel with appropriate biosafety precautions. Results should be interpreted by qualified healthcare professionals in conjunction with clinical findings.
