If only IgM or IgG titer is desired, order Isohemagglutinin Titer, IgG (2000271) or Isohemagglutinin Titer, IgM (2000270). Specimens are screened for antibodies; if positive, an antibody panel will be performed. Titers will be performed as indicated for specific blood groups. Additional charges will apply to antibody identification and titer testing.
