blood grouping test
blood-grouping test. A test used in paternity and illegitimacy cases to determine whether a particular man could be the father of a child, examples being the genetic-marker test and the human-leukocyte antigen test. • The test does not establish paternity; rather, it eliminates men who could not be the father. See PATERNITY TEST; GENETIC-MARKER TEST; HUMAN-LEUKOCYTE ANTIGEN TEST . [Cases: Children Out-of-Wedlock 58. C.J.S. Children Out-of-Wedlock §§ 75–76.]
