Tests
The determination of the number of mismatch between the study subject and his or her donor for the human leukocyte antigen, class I, group B (HLA-B).
Tests
The determination of the amount of Human rhinovirus A, B and/or C antigen in a biological sample.
Article
Research record from HLA, 2026-07-01. PMID 42478549.
Indicators
An immunoglobulin isotype (subclass). This isotype is expressed on naive B cells along with IgM. Little is known about its physiologic role.
Indicators
This gene is involved in protein phosphorylation.
Indicators
This gene is involved in B-cell and T-cell maturation.
Tests
The determination of the number of the immature B2 B-lymphocytes in a sample.
Tests
The determination of the number of the memory immature B-lymphocytes in a sample.
Indicators
Immunoglobulin Light Chain Kappa is one of two Ig light chain types. Each Ig molecule is typically composed of two heavy chains and two light chains. Ig kappa light chains contain a variable and a constant region. Kappa light chains are encoded by multiple V, J, and C gene segments, which are separated in the genomes of cells undifferentiated with regard to antibody gene expression. Diversity in the kappa light chain V region arises during differentiation of an activated (kappa-type) antibody-producing B-cell from variable recombination of kappa V genes with kappa J genes and somatic point mutation, which plays a major role in antibody diversity. (from OMIM and NCI)
Indicators
Immunoglobulin Light Chain Lambda is one of two Ig light chain types. Each Ig molecule is typically composed of two heavy chains and two light chains but Ig lambda light chains contain a variable and a constant region. Lambda light chains are encoded by multiple V, J, and C gene segments, which are separated in the genomes of cells undifferentiated with regard to antibody gene expression. During differentiation of an activated (lambda-type) antibody-producing B-cell, diversity in the lambda light chain V region arises from variable recombination of lambda V genes with lambda J genes and somatic point mutation, which plays a major role in antibody diversity. (from OMIM 147220 and NCI)
Tests
The determination of the ratio of IgM positive class-switched memory B-Lymphocytes to class-switched memory B-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
