What is the relationship between the number of HLA alleles that have been identified by serological methods as compared with DNA analysis methods?

Question

Quizplus · Accepted Answer

Serological methods rely on the detection of antigens, which can be defined by the presence of specific HLA alleles. However, DNA analysis methods allow for a more precise identification of the actual allele sequences, leading to the discovery of more alleles than can be identified by serological methods. Therefore, there are fewer serologically defined alleles than DNA analysis-defined alleles.
