Alloimmunization
Antibodies in carriers
Antibody specificity: D (RH1)
Summary: no published cases (last update: May 4, 2020)Detailed information
Antibodies in D negative recipients
Alloimmunization in recipients: yes, see detailed reports and phenotype data
-
Berardi P et al. Immunohematology (2015)
- Ab specificity: D (RH1)
- Number of cases: 1
- Exposures: 1 RBC unit with this variant, no other exposure
- Imputability:
- Comment: "postoperative anemia but no convincing evidence of hemolysis"; anti-D persisted at least a year; anti-LW and anti-G were ruled out; timing seemed consistent with secondary reaction rather than primary alloimmunization
Reports
Summary: rare descriptions, possible Western European descent (last update: May 4, 2020)Detailed reports

1/15446 first time donors with D negative phenotype, tested for D phenotype in immediate spin and IAT testing in the Canadian (Ontario) population, mainly White
(sample in common with
27187196 ) -
4 related samples donors with D negative phenotype, investigated after a recipient made anti-D Irish/English descent, in the Canadian (Manitoba) population
(1 sample in common with
24325169 ) - 1/104 (prevalence among weak D phenotype) or 1/21353 (phenotypic prevalence in population) 104 weak D phenotype were genotyped in a cohort of 21353 pregnant women admixed Brazilian
- 1 sample? reported by a German lab (FM201787)
