 Isohemagglutinin titers contain both IgM and IgG. Both IgG and IgM titers will be performed for this test. 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.
