...When these five antigens are examined, there are more than 18 types, which provide very useful information on genetics. However, when examining Rh blood type for clinical medical purposes such as blood transfusion, it is customary to first examine only the D antigen (see "Blood Types and Transfusions" below for the reason). By examining the D antigen, it is possible to distinguish between two types, Rh+ (positive, D+ type) and Rh- (negative, D- type). The frequency of Rh+ and Rh- varies by race and ethnicity, with 15-20% of whites and 3-10% of blacks being Rh-, while on average only 0.5% (about 1 in 200 people) of Japanese people are Rh- (however, in Okinawa, it is high at about 1%). ... *Some of the terminology that mentions "Rh+" is listed below.

…これら五つの抗原をしらべると型の種類は18型以上にもなり,遺伝学上きわめて有力な情報を提供してくれるが,輸血など臨床医学上の目的でRh血液型をしらべる場合には,まずD抗原だけを対象とするのが通例である(その理由については後述の〈血液型と輸血〉参照)。D抗原をしらべることによって,Rh+(陽性,D+型)とRh-(陰性,D-型)の2型を区別することができる。Rh+,Rh-の出現頻度は人種や民族によって異なり,白人の間ではRh-が15~20%,黒人では3~10%もあるのに,日本人では平均して0.5%(約200人に1人)ぐらいしかない(ただし沖縄では約1%と多い)。… ※「Rh+」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
