Glossary Term
A type of protein made by B lymphocytes in response to a foreign substance (antigen). Each antibody only binds to a specific antigen, helping to destroy the antigen directly or by assisting white blood cells to destroy the antigen.
Article
Research record from Int J Lab Hematol, 2026-06-10. PMID 42267646.
Tests
The determination of the ratio of a sub-population of antibody-secreting B-lymphocytes to antibody-secreting B-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Glossary Term
Any substance, generally a protein, that stimulates the immune system and elicits an immune response. Recognition by the immune system elicits either a T-lymphocyte response, recognizing processed antigens, or a B-lymphocyte response, producing antibodies that bind to unprocessed antigens.
Indicators
An autoantibody that recognizes antigens found in the cytoplasm of neutrophils.
