Background: The Rhesus (Rh) blood group is the most immunogenic blood group in humans among all blood groups. It is one of the complex systems in immunohematology containing 56 different antigens. The Rh blood group shows variable expression of D antigen due to gene polymorphism. The variable expressions are weak D, partial D, and DEL. Materials and Methods: A retrospective observational study was conducted at Evercare Hospital Chattogram from April 2021 to March 2023. Blood samples obtained for ABO and RhD blood grouping were tested by column agglutination technique. RhD negative samples were further tested for Du testing to identify weak-D phenotype. Results: A total of 5700 blood samples were taken from patients. Out of these 5496 (96.5%) were RhD positive while 204 (3.5%) were RhD negative. Among Rh D negative cases, 4 were weak-D positive constituting 1.9% among Rh D negatives and 0.07% among total patients. Conclusion: All RhD negative samples should be checked for Du testing. We must take caution on application of the Du test. It may be used to decrease the burden of RhD negative transfusion. Pulse Vol.15, 2023 P: 38-40

In this report, a case of a patient with COVID-19 pneumonia is presented who developed multi-organ failure and required mechanical ventilation. Despite multiple attempts at extubation, the patient remained intubated for…
Introduction: Arterial stiffening is a hallmark of vascular ageing, and unravelling its underlying mechanisms has become a central theme in the field of cardiovascular disease. While various techniques and experimental…
Over the years, the field that was once known as blood banking has evolved into the discipline of Transfusion Medicine. Transfusion Medicine has become a broad, multidisciplinary field which include various facets of…
Introduction It is not well-known which indicator, central blood pressure (CBP) or arterial stiffness, has a greater impact on carotid atherosclerosis. This study aimed to assess the associations of carotid…
Bombay blood group is a rare blood type. It was first discovered in Bombay (Mumbai) in India. At the time of blood grouping, this blood group mimics O blood group due to the absence of H antigen, but it shows…
