Tests
The determination of the ratio of a sub-population of lymphocytes to a sub-population of lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The number of lymphocytes found in a given volume of blood.
Tests
The measurement of the number of helper T lymphocytes, which are T lymphocytes that express CD4, in a cubic millimeter of blood. It is calculated by multiplying 1000 by both the total leukocyte count and the percent of helper T cells in the differential leukocyte count.

Tests
The measurement of the ratio of activated T-lymphocytes expressing CD4 to the total number of T-lymphocytes in a sample expressed as a percent value.
Tests
The determination of the number of helper alpha-beta T-lymphocytes in a sample.
Tests
The determination of the ratio of a sub-population of alpha-beta T-lymphocytes to total alpha-beta T-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The determination of the ratio of the alpha-beta T-lymphocytes to total T-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 antibody-secreting B-lymphocytes to antibody-secreting B-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The determination of the ratio of antibody-secreting B-lymphocytes to total class-switched memory B-lymphocyte present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The determination of the ratio of atypical lymphocytes to leukocytes in a blood sample. The measurement may be expressed as either a ratio or a percentage.
Tests
The determination of the number of the B1a B-lymphocytes in a sample.
