Is it accurate to irradiate antigen with a blue flashlight?

Not allowed. Fluorescent immunochromatographic antigen detection kit needs to use special band ultraviolet lamp (commonly known as ultraviolet reagent detection lamp or fluorescent color lamp) instead of blue flashlight, so it is not allowed. Antigen refers to a substance that stimulates the immune system to produce immune response in vivo or in vitro, produces antibodies and lymphocytes, and specifically binds to the corresponding antibodies and lymphocytes.
