Introduction: Haemolytic Disease of the Foetus and Newborn (HDFN) is widely known to be caused by the presence of irregular Red Blood Cell (RBC) antibodies in pregnant females. To prevent HDFN, it is crucial to identify these antibodies in pregnant women.
Aim: To evaluate the prevalence of irregular red cell antibodies in pregnant women in a tertiary care hospital.
Materials and Methods: A cross-sectional retrospective study was conducted in the Department of Transfusion Medicine at Indraprastha Apollo New Delhi, from November 2009 to December 2017. A total of 8,217 prenatal females were examined for irregular red cell antibodies. Antibody screening and blood grouping were performed. The Capture-R ready screen was used to confirm screen-positive tests. Adsorption, elution, and other advanced techniques were utilised as needed. Data was collected from patient records and entered into a Microsoft excel spreadsheet. The statistical analysis was conducted using Statistical Package for Social Sciences (SPSS) software version 14.0 (USA). Statistical tests, including the Chi-squared and Fisher’s exact test, were performed, with a p-value less than 0.05 considered statistically significant.
Results: Out of the 8,217 prenatal females examined, 105 (1.27%) had positive screening results with the four cell panel. Red cell alloimmunisation was observed in groups that were RhD negative (n=93/105; 88.57%) and positive (n=12/105; 11.42%). The most prevalent alloantibody among RhD negative individuals was alloantibody anti-D (n=83/93; 89.24%), followed by alloantibody anti C+ anti D (n=13/93; 13.97%). Anti-D was the most prevalent alloantibody overall (n=83/105; 79.04%).
Conclusion: Alloimmunisation rates were notably high among women lacking the Rh D antigen. Individuals with a history of adverse obstetric outcomes showed a statistically significant association with alloimmunisation. Therefore, it is recommended to screen such individuals for alloantibodies to enable early detection and improve the management of HDFN.
