Introduction: The prevalence of Bombay (Oh Phenotype) is not precisely known in Rajasthan state. Because of the fact that Bombay blood group is clinically significant, we decided to conduct a study at our centre to determine the prevalence of Bombay blood group among blood donor population in Western Rajasthan. Methodology: This blood bank based prospective study was carried out amongst the blood donors over a period of 11 months, i.e., from February 2019 to December 2019. Total 30,000 donor samples were screened for ABO-RhD blood grouping and antibody screening. Auto control, indirect antiglobulin test (IAT) and Bombay blood group (Anti-H lectin) tests were run on all the O blood group samples showing agglutination with O reagent cells (in reverse grouping). Donors negative on Anti-H testing were tested for saliva A, B and H antigens and interpreted. Results: Out of the total 30,000 donors, the maximum number of donors had blood group B+ (32.76%), followed by O+ (29.9%), A+ (20.41%), AB+ (8.06%), B- (3.11), O- (3.02%), A- (1.93%) and AB- (0.8%). Prevalence of Bombay blood group among study population was calculated to be 0.003%. Conclusion: Bombay phenotype is a rare blood group but not uncommon. If serum grouping is not performed, it is misdiagnosed as blood group O. Therefore both forward and reverse blood grouping should be done on 100% samples. Keywords: Bombay, Anti-H lectin, Serum grouping, Blood donors.

Background: People from certain blood groups are more prone to develop infections transmitted by blood transfusion. In order to improve the management of such infections some hypothesis suggests that genetic predispositions like ABO and Rh blood groups would inuence the occurrence of such infections. Hence the present study aims to assess any possible associations of ABO & Rh blood groups with Hepatitis, HIV & syphilis infections in healthy blood donors. This was a retrospective study in heal Methods: thy blood donors of tertiary care hospital enrolled during years 2016 to 2020. Blood samples from total 34015 donors were screened for blood grouping & serology of HIV, Hepatitis & Syphilis. Result: Out of total donors only 171 donors were found positive for transfusion transmitted infections. Hepatitis B virus was found more prevalent compared to other infections. In ABO blood group type “B” and in Rh blood group type “Positive” was found more prevalent in donors. But it did not show any signicant association with transfusion transmitted infections. Conclusion: High prevalence of HBV infections in blood donors in present study point towards need of public health measures in general population. Undertaking further research to determine the special blood groups as increased risk for categorized donors is recommended.

Introduction: It is important to know the frequencies of the various antigens to predict the availability of blood units for alloimmunized patients. Because of the fact that there is always a chance of diversity in phenotype pattern of a donor population, we decided to conduct a study on antigen phenotyping of regular blood donors. Methodology: This blood bank based cross-sectional analytical study was carried out amongst 500 voluntary blood donors over a period of 8 months, i.e., from April, 2019 to November, 2019. Samples from all these donors were subjected to extended phenotyping (C, c, E, e, K, M, N, S, Jka, Jkb, Fya, Fyb, Lea and Leb). Results: In present study, we observed the percentage frequencies of C, c, E, e, K, M, N, S, P1, Lea, Leb, Jka, Jkb, Fya and Fyb antigens as 75.6%, 53.2%, 18.4%, 97.75%, 3.8%, 82.4%, 58.4%, 43.8%, 66.2%, 16.8%, 52.6%, 80.0%, 67.6%, 79.4% and 54.6% respectively. Conclusion: Outcomes of such studies can be used to formulate a rare blood group donor registry and compatible blood can be provided to the patients (especially those requiring multiple transfusions). Keywords: Antigens, Phenotyping, Blood donors.

ABO blood group antigens have been identified as pathological agent in different disease conditions. For some time, the association of blood group with pregnancy associated conditions like pre-eclampsia is extensively under debate. Preeclampsia is a distressing condition of pregnancy which commonly causes maternal and fetal mortality around the globe. Multiple risk factors are found to be associated with preeclamptic occurrence. In this study our aim was to delineate a specific blood group which could be implicated as a risk factor for pre-eclampsia. Methods: This retrospective study was conducted in a tertiary care hospital of Karachi and retrieved obstetric data including blood group was from medical record files of 368 patients. Obtained data was analyzed by IBM SPSS version 21. Results: The prevalence of B group was recorded to be 41.3% as compared to O (26.1%), A (22.8%) and AB (9.8%). So, it can be concluded that women having blood group B are more prone to develop pre-eclampsia. Conclusion: Blood grouping of pregnant women in early weeks of pregnancy could assist in prediction or better management of pre-eclampsia.

Background: Blood grouping consists of both forward grouping; reverse grouping and both procedures should agree with each other.A blood group discrepancy exists when results of red cell testing do not agree with serum testing, usually due to unexpected negative or positive results in either forward or reverse typing. ABO and Rh blood group discrepancy is associated with incompatible transfusion reaction.Blood group discrepancy should be resolved before transfusion and blood group to be properly labeled to prevent transfusion reaction.Methods: A prospective study was carried in SCB blood bank which is under the Department of Transfusion Medicine, SCB Medical College and Hospital, Cuttack, Odisha from January 2015 to October-2016. Total 25,559 blood samples of patients were included in the study and hemolysed samples excluded. The ABO and Rh D typing was done by tube technique using monoclonal IgM (Tulip Diagnostic P Ltd.) Anti-A, Anti-B, Anti-D and pooled A, B and O cell.Results: A total of 25,559 blood group testing were done where we found 57 blood group discrepancies with overall frequency was 0.22%. Out of 57 discrepancies we were found 20 (35.09%) cases of technical error and 37 (64.91%) cases of sample related error. Among these sample related problems, we found weak/missing antibody, weak antigen expression, rouleaux, cold autoantibodies, cold alloantibodies, Bombay phenotype with the frequency of 13.51%, 2.70%, 2.70%, 54.06%, 8.11%, 18.92% respectively.Conclusions: Mistyping either a donor or a recipient can lead to transfusion with ABO-incompatible blood, which can result in severe hemolysis and may even result in the death of the recipient. Any discrepancy between forward and reverse blood grouping methods should be resolved before transfusion of blood components.

The Rhesus (Rh) blood group is the most polymorphic human blood group and it is clinically significant in transfusion medicine. Especially, D antigen is the most important and highly immunogenic antigen. Due to anti-D, it is the cause of the hemolytic disease of the newborn and transfusion reaction. About 0.1%–0.5% of Asian people are RhD-negative, whereas in the Thai population, the RhD-negative blood type only occurs in 0.3%. Approximately 10%–30% of RhD-negative in Eastern Asian people actually were D-elute (DEL) phenotype, the very weak D antigen that cannot be detected by indirect antiglobulin test (IAT). There are many reports about anti-D immunization in RhD-negative recipients through the transfusion of red blood cells from individuals with DEL phenotype. D-elute phenotype screening in Thai RhD-negative blood donors was studied to distinguish true RhD-negative from DEL phenotype. A total of 254 Thai serologically RhD-negative blood donors were tested for RhCE phenotypes and anti-D adsorption/elution test. In addition, RhC(+) samples were tested for RHD 1227A allele by SSP-PCR technique. The RhD-negative phenotype samples consisted of 131 ccee, 4 ccEe, 1 ccEE, 101 Ccee, 16 CCee, and 1 CcEe. The 42 Ccee and 8 CCee phenotype samples were typed as DEL phenotype and 96% of DEL samples were positive for RHD 1227A allele. The incidence of RhC(+) was 46.4%, and 48 of the 118 RhC(+) samples were positive for both anti-D adsorption/elution test and SSP-PCR technique for RHD 1227A allele. The sensitivity and specificity were 96% and 100%, respectively, for RHD 1227A detection as compared with the adsorption/elution test. In conclusion, RhC(+) phenotype can combine with anti-D adsorption/elution test and RHD 1227A allele SSP-PCR technique for distinguishing true RhD-negative from DEL phenotype.

Background & Objective: Practically, most important blood groups are A, B, O, AB and RhD(+/-), which are essential for right blood supply to the recipients and in various studies. The incidence of ABO and Rhesus (Rh) groups varies markedly in different parts of the world and in different races. The present study was aimed at determining the prevalence of ABO & RhD blood groups among healthy blood donors in Western Rajasthan. Material and Methods: At our centre, all the healthy blood donors were assessed and analyzed for ABO-Rh blood grouping during a period of previous 4 years (from January, 2015 to December, 2018). 119200 samples were checked for ABO and RhD blood grouping by manual saline antigen-antibody agglutination method using commercially prepared antisera antiA, antiB, antiAB, antiD, in house prepared reagent cells Acell, Bcell, Ocell and negative control. The results were reconfirmed on fully automated immunohematology analyzer (Galileo Neo, USA) with direct hemagglutination micro-well plates using antiA, antiB, antiD series-5, antiD Novaclone, Monoclonal control, Acell, Bcell and Ocell provided by the manufacturer. Discrepant samples were cross checked separately by column agglutination technique using DG Gel ABO/Rh-2D cards (Diagnostic Grifols S.A.) and tube technique. Results: We found that the most common blood group was B+ 39758 (33.35%) followed by O+, A+, AB+, B-, O-, A- and AB-. RhD negative donors were 10504 (8.81%) among the total donors. Phenotypic frequencies were expressed under the standard assumption of Hardy-Weinberg equilibrium. Conclusion: Present study concludes that the most common ABO phenotype found among healthy blood donors in Western Rajasthan (India) is group B with RhD negativity being 8.81%. Larger studies should be conducted to calculate antigenic, phenotypic and allelic frequencies in general population. Keywords: ABO-RhD blood group, Phenotype, Allele, Blood donors, hemagglutination.

Background: Globally, breast cancer contributes to 27.7% of the newly diagnosed cases of cancer among women. Early screening and timely diagnosis of the lesions of breast help in alleviating the anxiety among patients. Histopathology is the gold standard in diagnosing the lesions, assessing the adequacy of treatment, and in disease prognosis. Studies have shown that ABO blood type has been associated with risk and survival for several malignancies. However, data for an association with breast cancer are inconsistent. Aim: To study the histopathological spectrum breast carcinomas and to investigate the presence of a possible association between breast cancer in women and ABO blood group and Rh factor. Materials and Methods: This retrospective descriptive study was done for a period of 4 years on 110 mastectomy specimens histopathologically diagnosed as breast cancers, and clinico-pathological data collected and analysed with records from the Department of Pathology, Saveetha Medical College. Association of breast cancer with ABO blood grouping and Rh typing was studied.  Results: Left breast was involved in most cases (96.4%). The mean age was 50.86 years, with 41-50 years age group showing peak incidence. Infiltrating breast carcinoma, no special type (89.6%) was the most common histological type. ER and PR positivity was seen in 46.4% and 41.8% of cases respectively. A statistically significant association was seen between hormone receptor status and histological grade. 39.1% cases belonged to O blood group, and Rh positivity was seen in 96.4% of the cases. No association was found between breast cancer and ABO/Rh blood grouping.
