ese varying blood subgroups, A2B is one of the rare subgroups of ABO blood group system. Because of the weak antigen. c power of A2 subgroups, hemolytic reaction is not severe under normothermic situations. But under hypothermic conditions. such as in cardiac surgery under hypothermic CPB, lethal hemolytic reactio. niversity of M. dical.
Persons who are in primary blood groups (also known as blood type) A and AB can be further tested to determine a more specific subgroup (also known as a subtype). Subtypes for blood type A include A1, A2, Ax, Aint and others, but the most common is A1.
The ABO blood group - Blood Groups and Red Cell Antigens - NCBI Bookshelf
People with the common blood type O express neither the A nor B antigen, and they are perfectly healthy. Numerous associations have been made between particular ABO phenotypes and an increased susceptibility to disease.
ABO subgroups - Professional Education
ABO subgroups can result in irregularities or discrepancies observed during ABO typing of a red blood cell unit. For instance, a subgroup that leads to reduced expression of A antigen, such the A 2 subgroup, may result in a weaker forward reaction during typing.
Blood group “A, non-A1” organs are transplanted in many centers into blood group O or B candidates, and blood group “AB, non-A1B” organs into blood group B candidates.
ABO blood group system - Wikipedia
The ABO blood group system is used to denote the presence of one, both, or neither of the A and B antigens on erythrocytes (red blood cells). [1] .

2018年8月1日 · Most blood bankers call it the “front-type,” but others call it “cell grouping” or “forward grouping.” Whatever you call it, this simple test gets you halfway to determining someone’s ABO type.
Prevalence of A2 and A2B Subgroups and Anti-A1 Antibody in Blood …
2020年7月18日 · Purpose: A 2 and A 2 B are rare phenotypes of the ABO blood group system. Some individuals with A 2 and A 2 B may have anti-A 1 antibodies that may be clinically significant or insignificant. The aim of this study was to determine the frequency of A 2, A 2 B phenotypes and anti-A 1 antibodies in blood donors in Jazan, Saudi Arabia.
ABO Genotyping finds more A2 to B kidney transplant …
2022年9月26日 · ABO compatibility is important for kidney transplantation, with longer waitlist times for blood group B kidney transplant candidates. However, kidneys from non-A 1 (eg, A 2) subtype donors, which express less A antigen, can be safely transplanted into group B recipients.
A2/A2B Deceased Donor Kidney Transplantation Using A2 Titers …
2024年5月21日 · In this single-center study, we aimed to determine the safety and effect of A2/A2B transplantation on deceased donor kidney transplantation using an A2 titer threshold of ≤1:8 IgG and ≤1:16 IgM in blood type B recipients.
