Tests
The measurement of the number T lymphocytes, which are leukocytes that express CD3, in a cubic millimeter of blood. It is calculated by multiplying 1000 by both the total leukocyte count and the percent of T cells in the differential leukocyte count.
Indicators
Granular leukocytes with a nucleus that usually has two lobes connected by a slender thread of chromatin, and cytoplasm containing coarse, round granules that are uniform in size and stainable by eosin.
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 A (HLA-A).
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 ratio of the human leukocyte antigen DR (HLA-DR) to total cells present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The identification of the type of human leukocyte antigen, class II, antigen-D-related 52 (HLA-DR52), in a sample.
Indicators
A class of interferon (leukocyte interferon) produced predominantly by B lymphocytes. Located in a cluster on 9p22 there are at least 13 functional genes and 1 pseudogene.
Indicators
Interleukin-2 (153 aa, ~18 kDa) is encoded by the human IL2 gene. This protein is involved in T-cell proliferation, leukocyte stimulation and immune responses.
Indicators
Large, phagocytic mononuclear leukocytes produced in the vertebrate bone marrow and released into the blood; contain a large, oval or somewhat indented nucleus surrounded by voluminous cytoplasm and numerous organelles.
Tests
The measurement of the ratio of natural killer cells, which are leukocytes that express CD16 and CD56, to the total number of blood cells in a sample expressed as a percent value.
Indicators
Granular leukocytes having a nucleus with three to five lobes connected by slender threads of chromatin, and cytoplasm containing fine inconspicuous granules and stainable by neutral dyes.
Tests
This test looks for white blood cells in a sample of your stool (poop). White blood cells are also called leukocytes, so this test is sometimes called a leukocytes in stool test.
