Abstract:
Background: The Rhesus (Rh) blood group system, particularly the D antigen, holds critical importance in transfusion and obstetric medicine. Rh incompatibility between a pregnant woman and her fetus can lead to hemolytic disease of the fetus and newborn (HDFN), a life-threatening condition. Despite the clinical significance, comprehensive data on the prevalence of Rh-negative blood types among pregnant women in Sudan remains limited. Objective: This study aimed to determine the prevalence of Rh-negative blood types among pregnant women attending antenatal care at Port Sudan Teaching Hospital in 2025, and to examine the distribution of ABO blood groups and their association with Rh factor. Methods: A descriptive cross-sectional study was conducted on 100 pregnant women. Data were collected via structured interviews and laboratory testing using the slide agglutination method to determine ABO and Rh blood groups. Statistical analysis was performed using SPSS version 26. Results : The majority of participants were aged 21-25 years (32%). Blood group O was the most common (49%),followed by A (26%) and B (25%). The prevalence of Rh-negative blood type was 16%, while 84% were Rh positive. No statistically significant association was found between ABO blood group and Rh factor (p = 1.00). Conclusion: This study highlights a notable prevalence of Rh-negative blood type among pregnant women in pPort Sudan, higher than some regional data. The findings emphasize the importance of routine antenatal screening and the availability of anti-D immunoglobulin to prevent Rh alloimmunization and associated complications ..
