MERISERA® Anti-D (IgG+IgM) — Dual Antibody Reagent for Rh(D) Typing and Weak D Detection

MERISERA® Anti-D (IgG+IgM) is a blend of monoclonal IgM and IgG anti-D antibodies for comprehensive Rh(D) blood group typing. The IgM component provides immediate spin/slide agglutination for routine Rh typing, while the IgG component enables detection of weak D (Du) variants via the indirect antiglobulin test (IAT/Coombs test). This dual-antibody format is the blood bank gold standard for complete Rh(D) determination.

Why IgG+IgM Matters

Standard IgM-only Anti-D detects most Rh(D) positive samples but can miss weak D (Du) variants — individuals with reduced D antigen expression. If mistyped as Rh-negative, these patients may receive Rh-negative blood unnecessarily (wasting a scarce resource) or, if donors, their Rh-positive units may be transfused to Rh-negative recipients causing alloimmunization. The IgG+IgM blend ensures no weak D is missed — IgG antibodies sensitize weak D cells for detection by AHG in the Coombs phase.

Key Features

  • Dual Antibody Blend: IgM for direct agglutination (routine typing) + IgG for IAT/Coombs phase (weak D detection)
  • Weak D (Du) Detection: Detects partial and weak D variants that IgM-only reagents miss — critical for blood bank safety
  • High Avidity: Strong immediate agglutination on slide/tube for routine Rh typing
  • High Titre: ≥1:128 — reliable in both direct and indirect phases
  • AABB/DGHS Compliant: Meets blood bank regulatory requirements for complete Rh(D) determination
  • Free from TTI: Negative for HIV-1/2, anti-HCV, and HBsAg
  • 10ml Pack: Dropper bottle for routine use

Clinical Applications

  • Complete Rh(D) typing including weak D (Du) detection in blood banks
  • Donor Rh typing — ensures weak D donors are correctly classified as Rh-positive
  • Antenatal Rh determination — accurate typing guides anti-D immunoprophylaxis decisions
  • Newborn Rh typing in HDFN investigation
  • Resolution of Rh typing discrepancies
  • Quality control for Rh(D) testing in transfusion services
