Knowing the distribution of blood group distribution within a population is crucial in determining the direction of blood bank inventory for emergency blood services. Object: For the first time, we know the blood group distribution pattern for Ghana's Volta region. Method: For O+, B+, B-, and AB-blood groups respectively, the percentages were extracted and evaluated from 14,360 medical records of blood donors and recipients at seven major hospitals in the Volta area for a period of seven years.

This paper is part of a series of journal publishing the results from the International Society of Blood Transfusion Working Party's Immunohaematology Workshop on the Clinical Significance of Red Blood Cell Alloantibodies. The workshop was designed to analyze evidence regarding the use of alloantibodies to red blood cell antigens that have been recognized by the ISBT.

Abstract The aim of this research was to determine the prevalence of ABO and Rh phenotypes in the general Pakistan population. In the study, a total of 242 patients with blood disorders requiring frequent blood transfusions were enrolled. Following were the following: the prevalence of ABO and D phenotypes in ABO and D: group O, D+, group O, D+, group B, D+, group A, D+, group A, D–, and group A, D+, respectively. R 1 R 1 r 1 r, R 1 r, R 1 r, R 1 r, R 1 r, R 1 r, R 1 r, R 1 r, R 1 r, R 1 R 2 r, R 1 r, R 1 R 1 r, R 1 r, R 1 r, R 1 r 1 r, R 1 r r, R 1 r 1 r 1 r 1 r 1 r 1 r 1 r 1 r r, R 1 r 2 r 1 The highest rate of ABO phenotypes in our study was group O, and the most prevalent Rh antigen was e. Rh phenotyping, as well as antibody screening and identification should be done prior to transfusion of patients requiring multiple transfusions to reduce or possibly prevent the rate of alloimmunization.

The O 2 allele was not identified in the Han population, and the frequencies of A 1, A 2, B. , and O 1 alleles were 0. 189, 0. 170, and 0. 638, respectively, and the O2 allele was not identified. The frequencies of C and c alleles were 0. 67 and 0. 33, respectively, and 0. 78 and 0. 78, respectively, among D+ Hans. Fy a and Fy b alleles had frequencies of 0. 94 and 0. 06 among Hans and 0. 98 and 0. 02 among Shes, respectively. Among Hans, Jk a and Jk b alleles were 0. 49 and 0. 51 among Hans, and 0. 56 and 0. 44 among Shes, respectively. Among Tajiks, respectively, the frequencies of Yt a and Yt b alleles were 0. 94 and 0. 06 respectively. Both Han and Tajik ethnic groups had the Sc1 allele at 1. 00 in all Han and Tajik ethnic groups.

Abstract On the PK 7200 blood grouping system, the success of ready-to-use kits was evaluated. Anti-A, B, and D antigens were tested for first and second determinations of A, B, and D antigens by The Olymp Group and Olymp Group II, which contained anti-A, -B, -AB, and -D reagents. Three discrepancies were discovered with kit 1 in group A and B RBCs, as well as kit 1. The kit 1 anti-A reagent detected A3 but not A3 but not A 3. But not A x RBCs and anti-AB reported both. Six out of eight poor D phenotypes were positive with kit 1, while six others were positive with kit 1. Only one of five poor D phenotypes was found with kit 2, only one of five was found.

Samples of Rh antigens were typed for five hundred and thirty samples. When tested against a panel of over fifty monoclonal IgG and IgM anti-Ds, seven D VI variants and seven D U s were identical to the seven D U s, with some of them being D U s and seven D U s. The correct results were obtained from 554 samples tested for the K1 antigen.

The ABO and Rh phenotypes in three groups in the total sample were similar to those reported from most places in the Arabian region.

The most common types of blood group types in man are MN, ABO, and Rh blood group systems; many methods are used to classify blood group types in man. The ABO blood group system is the most common among the above mentioned categories, and it is used to classify blood group types. Antigen A is present in red blood cells of people with A blood type A. Persons with the blood type B have antigen B in their red blood cells. Both the antigens A and B are present at the same time, according to blood group A, which is due to the complete absence of any antigen. In emergency situations, when blood transfusion is required, the blood groups of donor and recipient are cross matched because of compatibility issues that could result in deleterious consequences if red blood cells are attacked. People with a blood group AB can donate blood from any other group so they are called universal donors. Universal donors are also accepted by blood groups O, if you're looking for a unique donor. Order primates of class mammalia and in Old World Monkeys have ABO blood group forms, according to sources . The Rh system, which is the second most common method to classify blood group types, is . Both the variables come into contact as a result of blood transfusion .

Introduction: Blut types were first identified by Karl Landsteiner, an Austrian physician. He discovered that blood sera from various individuals would clump together when mixed in test tubes, and that human blood would be agglutinated with animal blood. The study of various blood groups is crucial because it plays a major role in blood transfusion, some medico-legal cases, especially litigated paternity, etc. Aim: This study was conducted in order to determine the presence of ABO, Rhesus, and Bombay blood groups among donors at a tertiary care hospital. Conclusion: The most common blood group among donors was O Rh positive, with Bombay blood group being the least prevalent. Any blood bank should have a log of ABO and Rh grouping as it is vital for its efficient operation. Safe transfusion reduces the risk of transfusion-related illnesses and consequently improves patient safety.

The aim of this research was to identify ABO blood types and Rh factors, as well as their roles in GDM prevalence. According to the presence of GDM using the hospital's database system, 1017 pregnant women admitted to our clinic between January 1, 2015 and May 1, 2021, were evaluated between January 1, 2015 and May 1, 2021. All patients and GDM prevalence was determined, according to the groups, and comparison of the groups revealed that the ABO blood types and Rh factors were determined in all patients, and GDM prevalence was determined in all patients and Rh factors. Results: The 1017 pregnant women underwent single- and double-step oral glucose tolerance tests as well as the ABO blood type results were included in the study. The mean maternal age of the GDM group in the normal group was 30. 94. 8 years and it was 27. 85. 4 years in the normal group, which was a statistically significant difference. Conclusion: Our findings showed that ABO blood types and Rh factors were not risk factors for GDM.
