Indicators
White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each); those with characteristics of neither major class are called null cells.
Glossary Term
A class of RNA molecule containing protein-coding information in its nucleotide sequence that can be translated into the amino acid sequence of a protein.
Tests
The determination of the amount of MHC class I chain related protein A in a sample.
Tests
The determination of the amount of memory non-class switched IgG-positive B-lymphocytes present in a sample.
Tests
The determination of the amount of B-lymphocytes memory non-class switched IgM+ present in a sample.
Tests
The determination of the ratio of memory non-class switched IgM-positive B-lymphocytes to B-lymphocytes memory non-class switched present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The determination of the ratio of a sub-population of non-class-switched memory B-lymphocytes to total B-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The determination of the ratio of a subpopulation of non-class-switched memory B-lymphocytes to a subpopulation of non-class-switched memory B-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The determination of the ratio of a sub-population of non-class-switched memory B-lymphocytes to total non-class-switched memory B-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The determination of the ratio of B-lymphocytes memory non-class switched to leukocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The determination of the ratio of plasma cells to class-switched memory B-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Indicators
A non-essential amino acid in humans (synthesized by the body), Serine is present and functionally important in many proteins. With an alcohol group, serine is needed for the metabolism of fats, fatty acids, and cell membranes; muscle growth; and a healthy immune system. It also plays a major role in pyrimidine, purine, creatine, and porphyrin biosynthetic pathways. Serine is also found at the active site of the serine protease enzyme class that includes trypsin and chymotrypsin. (NCI04)
