Genotypes of the ABO blood group system were investigated using a multiplex PCR and subsequent restriction enzyme digestion on experimental blood stains. Differences were found when typing blood between the PCR and serological methods and one blood sample, typed as B with the agglutination test was classified as AB using the method described here. The subsequent sequencing procedure revealed the genotype to be BB. Methodological causes for errors in typing which should be taken into consideration are discussed.

UI	MeSH Term	Description	Entries
D001788	Blood Grouping and Crossmatching	Testing erythrocytes to determine presence or absence of blood-group antigens, testing of serum to determine the presence or absence of antibodies to these antigens, and selecting biocompatible blood by crossmatching samples from the donor against samples from the recipient. Crossmatching is performed prior to transfusion.	Blood Typing,Crossmatching, Blood,Blood Grouping,Blood Crossmatching,Grouping, Blood,Typing, Blood
D001801	Blood Stains	Antigenic characteristics and DNA fingerprint patterns identified from blood stains. Their primary value is in criminal cases.	Blood Stain,Stain, Blood,Stains, Blood
D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D005091	Exons	The parts of a transcript of a split GENE remaining after the INTRONS are removed. They are spliced together to become a MESSENGER RNA or other functional RNA.	Mini-Exon,Exon,Mini Exon,Mini-Exons
D005838	Genotype	The genetic constitution of the individual, comprising the ALLELES present at each GENETIC LOCUS.	Genogroup,Genogroups,Genotypes
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000017	ABO Blood-Group System	The major human blood type system which depends on the presence or absence of two antigens A and B. Type O occurs when neither A nor B is present and AB when both are present. A and B are genetic factors that determine the presence of enzymes for the synthesis of certain glycoproteins mainly in the red cell membrane.
