Noninvasive fetal <jats:italic>RHD<\/jats:italic> genotyping, used as a screening tool, enables targeted antenatal prophylaxis and has been implemented in several European countries. Despite the success of anti\u2010D prophylaxis programs, D alloimmunization still occurs and addressing these gaps is essential to ensure optimal maternal care. In pregnancies affected by HDFN, Doppler ultrasound assessment of middle cerebral artery peak systolic velocity (MCA\u2010PSV) is the gold standard for detecting fetal anemia, though its reliability following intrauterine blood transfusion (IUT) remains debated. IUT is the primary treatment for severe fetal anemia; however, it remains an invasive procedure with inherent risks, particularly when performed early in pregnancy. Intravenous immunoglobulin (IVIG) has been proposed as a treatment, though its efficacy remains inconclusive. A promising alternative involves monoclonal antibodies blocking the neonatal Fc receptor (FcRn), reducing IgG recycling and placental transfer\u2014with the potential to delay or obviate the need for IUT. This review provides an overview of fetal <jats:italic>RHD<\/jats:italic> genotyping in modern obstetric care and discusses prenatal monitoring and treatment strategies for HDFN within high\u2010quality healthcare settings.<\/jats:p>","DOI":"10.1002\/pd.6891","type":"journal-article","created":{"date-parts":[[2025,9,20]],"date-time":"2025-09-20T02:59:19Z","timestamp":1758337159000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Hemolytic Disease of the Fetus and Newborn: Fetal <i>RHD<\/i> Genotyping, Targeted Prophylaxis, and Prenatal Therapies"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6546-5544","authenticated-orcid":false,"given":"Emilie","family":"Thorup","sequence":"first","affiliation":[{"name":"Center of Fetal Medicine Department of Gynecology Fertility and Pregnancy Copenhagen University Hospital Rigshospitalet  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steffen","family":"Thorsen","sequence":"additional","affiliation":[{"name":"Department of Clinical Immunology Copenhagen University Hospital Rigshospitalet  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8034-1523","authenticated-orcid":false,"given":"Morten Hanefeld","family":"Dziegiel","sequence":"additional","affiliation":[{"name":"Department of Clinical Immunology Copenhagen University Hospital Rigshospitalet  Copenhagen Denmark"},{"name":"Department of Clinical Medicine Faculty of Health and Medical Sciences University of Copenhagen  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olav Bj\u00f8rn","family":"Petersen","sequence":"additional","affiliation":[{"name":"Center of Fetal Medicine Department of Gynecology Fertility and Pregnancy Copenhagen University Hospital Rigshospitalet  Copenhagen Denmark"},{"name":"Department of Clinical Medicine Faculty of Health and Medical Sciences University of Copenhagen  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2487-5373","authenticated-orcid":false,"given":"Frederik Banch","family":"Clausen","sequence":"additional","affiliation":[{"name":"Department of Clinical Immunology Copenhagen University Hospital Rigshospitalet  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,9,19]]},"reference":[{"key":"e_1_2_14_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cll.2020.10.009"},{"key":"e_1_2_14_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/aog.0000000000005709"},{"key":"e_1_2_14_4_1","doi-asserted-by":"publisher","DOI":"10.1159\/000491788"},{"key":"e_1_2_14_5_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.4.5675.84"},{"issue":"21","key":"e_1_2_14_6_1","first-page":"1245","article-title":"The Pathogenesis and Prevention of Rh Immunization","volume":"97","author":"Zipursky A.","year":"1967","journal-title":"Canadian Medical Association Journal"},{"key":"e_1_2_14_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365\u20103148.2011.01106.x"},{"key":"e_1_2_14_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/vox.12265"},{"key":"e_1_2_14_9_1","doi-asserted-by":"publisher","DOI":"10.2450\/BloodTransfus.712"},{"key":"e_1_2_14_10_1","doi-asserted-by":"publisher","DOI":"10.1080\/14737159.2018.1461562"},{"key":"e_1_2_14_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.transci.2024.103969"},{"key":"e_1_2_14_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2015.01.059"},{"key":"e_1_2_14_13_1","doi-asserted-by":"publisher","DOI":"10.1056\/nejm200001063420102"},{"key":"e_1_2_14_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.1882"},{"key":"e_1_2_14_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.20273"},{"key":"e_1_2_14_16_1","doi-asserted-by":"publisher","DOI":"10.1080\/17474086.2017.1305265"},{"key":"e_1_2_14_17_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.17319"},{"key":"e_1_2_14_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2024.03.044"},{"key":"e_1_2_14_19_1","doi-asserted-by":"publisher","DOI":"10.1056\/nejmoa2314466"},{"key":"e_1_2_14_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/vox.13172"},{"key":"e_1_2_14_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.transci.2020.102950"},{"key":"e_1_2_14_22_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1537\u20102995.2008.01742.x"},{"key":"e_1_2_14_23_1","doi-asserted-by":"publisher","DOI":"10.1186\/1471\u20102393\u201014\u201087"},{"key":"e_1_2_14_24_1","unstructured":"ACOG.
