Laboratory tests to identify the viral genome, the antigen, or specific antibodies are used for a definitive diagnosis of avian metapneumovirus (AMPV) infection. Methods that can be used for antibody determination are the virus neutralization test and the enzyme-linked immunosorbent assay. To monitor the presence of AMPV in Korean chickens, sera were taken from chickens in 20 flocks. Of the 197 serum samples tested by enzyme-linked immunosorbent assay, 144 (73.1%) were positive for AMPV. The
