2-21. OTHER Rh ANTIGENS
a. Background. The number of identified Rh antigens has now exceeded 40.
Except for the rare individuals and laboratories involved, most have primarily theoretical
importance. Table 2-12 lists most of the antigens sufficiently well characterized to have
names and/or numbers. The advantages of the numerical nomenclature are obvious at
these esoteric levels. A few antigens deserve additional comment.
NOTE:
No specific references are given. The reader is referred to Race and Sanger,
Issitt and Issitt, and to the papers by Rosenfield and colleagues.
