Table 1 | Diagnosis of swine-origin influenza A virus..

Method	Description
ELISA-assisted PNA array	Advantages -No viral RNA purification necessary -Sensitive (detection limit:10⁴ pfu^a) -Detect the presence of a viral gene presence using the naked eye Disadvantages -ELISA system anti-NP antibody is necessary -Diagnosis requires 2-3 hours.
Gold-conjugated antibody-assisted PNA chromatography	Advantages -Rapid (result can be obtained in 5 min) -No virus purification, incubation or washing necessary -Sensitive (detection limit: 10⁴ pfu) -Detect viral gene presence by the naked eyes Disadvantages -Gold-nanoparticle conjugated anti-NP antibody is necessary
