How Does Paternal Lymphocyte Immunization Procedure Work?
- Screening & LAD Testing: Following thorough blood donor screening, a Leukocyte Antibody Detection (LAD) test is performed to confirm patient eligibility before proceeding.
- Lymphocyte Preparation: High-purity white blood cells are isolated and concentrated from the blood sample of the partner or donor using advanced laboratory separation.
- Intradermal Injections: Specialist IVF Doctors in Punjab administer the concentrated lymphocyte solution via shallow injections into the mother's forearm across 1–2 sessions spaced 3–4 weeks apart.
- Immune Conditioning & Boosters: The therapy aims to build maternal immune tolerance, with local redness among possible reactions. Any further treatment or boosters should be guided by a qualified specialist at the Best Fertility Clinic in Jalandhar and Amritsar.
