The Spectrum CMV IgG/IgM Rapid Test is a lateral flow chromatographic immunoassay panel device. The test cassette consists of a CMV IgM detection panel (The left panel) and a CMV IgG detection panel (the right  panel).  The  IgM  panel  has  1)  a  burgundy  colored  conjugate pad  containing  mouse  anti-human  IgM  conjugated  with  colloid  gold (IgM  conjugates),  2)  a  nitrocellulose  membrane  strip  containing  a test band (T band) and a control band (C band). The T band is pre- coated with recombinant CMV antigen, and the C band is pre-coated with goat anti-mouse IgG.The IgG panel has 1) a burgundy colored conjugate pad containing CMV antigens conjugated with colloid gold (CMV conjugates) and rabbit IgG-gold conjugates, 2) a nitrocellulose membrane strip containing a test band (T band) and a control band (C band). The T band is pre-coated with anti-human G antibody, and the C band is pre-coated with goat anti-rabbit IgG.
