Serological and molecular biological analysis of RhD--: a case report
Journal Title: Chinese Journal of Blood Transfusion - Year 2023, Vol 36, Issue 12
Abstract
Objective To study the blood group serology and molecular biology of patients with RhD--, so as to guide clinical blood use. Methods The EDTA-K2 anticoagulant blood of the patient was detected for Rh antigens and antibodies. Meanwhile, DNA was extracted, and the 1-10 exon of RHCE and RHAG gene was sequenced by Sanger sequencing. Results The serological test showed O type RhD--, and all spectral cells were positive. RHCE gene sequencing showed RHCE*02/RHCE*02, RHAG gene sequencing showed mutations at site 808 G > A and site 861 G > A of exon 6. Conclusion When patients were with RhD--, and related immune conditions such as pregnancy and/or transfusion history were present, autologous blood transfusion or plasma exchange could be an option for emergency blood use.
