Blood Group Terminology 1995: ISBT Working Party on Terminology for Red Cell Surface Antigens

Since the first human blood groups were discovered almost a century ago, many hundreds of new red cell antigens have been identified. Because of the extended time period over which these antigens were discovered, a variety of different terminologies has been introduced. In some cases single capital letters were used (A, B, M, K), in some superscripts distinguished allelic products (Fy’, Fyh), and in some a numerical notation was introduced (Fy3). Some antigens were given different names in different laboratories, based on alternative genetic theories (D and Rho). In 1980 the International Society of Blood Transfusion (ISBT) established a Working Party to devise a genetically based numerical terminology for red cell surface antigens. In 1990 the Working Party published a monograph describing a numerical terminology for 242 red cell antigens [I], and brief updatings followed in 1991 [2] and 1993 [3]. In the 6 years since the 1990 report many amendments to the classification have been necessary: 18 new antigens have been identified and 6 others declared obsolete due to lack of suitable reagents; four new systems have been created (all from existing collections); the Auberger antigens joined the Lutheran system; the Gregory antigens and Jo” joined the Dombrock system; the Wright antigens joined the Diego system. Furthermore, since, 1990, many of the blood group genes have been isolated: of the genes controlling the 23 systems, only four (PI, JK, SC, DO) remain to be cloned. The purpose of this monograph is to describe the ISBT terminology for red cell surface antigens and to tabulate the complete 1995 version of the classification. In addition, an alternative ‘popular’ terminology is suggested in an attempt to reduce the number of different names used in publications on red cell antigens. Much of the information provided in the 1990 monograph [l] is reiterated here so that referral back will not generally be required, but only references after 1990 are provided.

International Society of Blood Transfusion Working Party on red cell immunogenetics and blood group terminology: Berlin report.

The International Society of Blood Transfusion Working Party on red cell immunogenetics and blood group terminology convened during the International congress in Cancun, July 2012. This report details the newly identified antigens in existing blood group systems and presents three new blood group systems.

International Society of Blood Transfusion Committee on Terminology for Red Cell Surface Antigens: Cape Town report.

The Committee met in Cape Town during the 2006 Inter-national Society of Blood Transfusion (ISBT) Congress (seeAppendix 1 for Committee members). Some changes to theclassification documented in Blood Group Terminology 2004[1] were agreed and are described below. The full updatedclassification can be found on the Blood Group Terminologywebsite at http://www.blood.co.uk/ibgrl. New antigens wereadded to the MNS, Kell, Scianna, Cromer, Indian, Knops,and JMH systems (Table 1). In line with convention, aminoacid positions are numbered with the translation-initiatingmethionine as 1, although the more traditional numberingfor glycophorin A, with number 1 representing the first aminoacid of the mature protein, is also provided.

International Society of Blood Transfusion Committee on terminology for red blood cell surface antigens: Macao report

The committee met in Macao Special Administrative Region,China, during the 2008 International Society of Blood Trans-fusion (ISBT) Congress. Some changes to the classificationdocumented in Blood Group Terminology 2004 [1] and updatedin 2007 [2] were agreed and are described below. The fullupdated classification can be found on the blood groupterminology website at http://www.blood.co.uk/ibgrl. A newblood group system, the RHAG system, was established andnew antigens were added to the Rh, Kell, and Dombrocksystems (Table 1). A total of 308 antigens are now recognized,270 of which are clustered in 30 blood group systems.

Transfusion reactions: prevention, diagnosis, and treatment

Blood transfusion is one of the most common procedures in patients in hospital so it is imperative that clinicians are knowledgeable about appropriate blood product administration, as well as the signs, symptoms, and management of transfusion reactions. In this Review, we, an international panel, provide a synopsis of the pathophysiology, treatment, and management of each diagnostic category of transfusion reaction using evidence-based recommendations whenever available.

Terminology for red cell surface antigens

The Working Party met at Makuhari Messe, Japan on 31 March 1996. A few changes to the current classification, documented in Blood Group Terminology 1995 [1], were agreed and these are described below.

External Financial Aid to Blood Transfusion Services in Sub-Saharan Africa: A Need for Reflection

Jean-Pierre Allain and colleagues argue that, while unintended, the foreign aid provided for blood transfusion services in sub-Saharan Africa has resulted in serious negative outcomes, which requires reflection and rethinking.
