Absolute CD19+ Cells details
What Absolute CD19+ Cells shows
CD19 is a marker found on B cells, the white blood cells that mature into the cells that make antibodies. This result is the absolute count, meaning the number of CD19+ cells in a given volume of your blood, calculated from the lymphocyte count and the percentage that are CD19+. It is measured to look at your immune system when infections are frequent, when an immune disorder is suspected, or to follow certain treatments that target B cells. A low count can point to an immune deficiency or the effect of such treatments, while a high count can be seen with some blood disorders. It is interpreted alongside the percentage and your other lymphocyte results.
Tests that include Absolute CD19+ Cells
T-lymphocyte count assists in evaluating cellular immunocompetency.
- CD4/CD8 Ratio Compares two types of immune T-cells. Used to assess immune system balance, especially in HIV monitoring and some autoimmune or infectious conditions.
- Absolute CD19+ Cells Counts the number of CD19+ B cells per volume of blood, the immune cells that make antibodies, used to assess immune system health.
- Absolute CD3+ Cells Counts the number of CD3+ T cells per volume of blood, the main immune cells that direct and carry out immune responses, to assess immune health.
- Absolute CD4+ Cells Counts CD4 'helper' T-cells, a key part of your immune system. Widely used to monitor immune health in HIV and other immune conditions.
- Absolute CD8+ Cells Counts CD8 'cytotoxic' T-cells, immune cells that help destroy infected or abnormal cells. Used to assess immune status.
- CD19 (B Cells) (%) Shows CD19-positive B cells as a percentage of your lymphocytes, helping assess the antibody-producing part of your immune system.
- Mature T Cells (CD3) (%) Shows CD3-positive mature T cells as a percentage of your lymphocytes, helping assess the T cell part of your immune system.
- CD4 (%) The percentage of your lymphocytes that are CD4 helper T-cells, used alongside the absolute CD4 count to assess immune function.
- CD8 (%) The percentage of your lymphocytes that are CD8 cytotoxic T-cells, used alongside the absolute count to assess immune function.
- Lymphocytes The number of lymphocytes, white blood cells central to your immune response (including T-cells, B-cells, and NK cells), in your blood.
