LP100021-7   Cells.CD3+CD8+
HIV infection decreases the number of CD3+ CD4+ lymphocytes (also called CD4 T cells or T4 helper cells) while increasing (momentarily) the numbers of CD3+CD8+ lymphocytes (called CD8 T lymphocytes or cytotoxic T cells). Thus the ratio of CD4/CD8 lymphocytes is decreased. These counts are used for prognostic purposes and to guide in the retroviral therapy. CDC has emphasized since 1997 that the number of CD3+ lymphocytes is necessary in addition to the number of CD4+ cells to reliably identify the T4 helper cells and the number of CD8+ cells. Laboratory reports that include only CD4 or only CD8 in their nomenclature are most likely really measuring CD3+CD4+ cells and CD3+CD8+ cells, respectively. Source: Regenstrief Help

LP200623-9   Cells.CD38+HLA-DR+
Activated T-cells are characterized by coexpression of CD38 and HLA-DR and may be measured as fractions of CD4+ and CD8+ T-cell populations. In patients with HIV, activated T-cell levels are directly correlated to viral load and inversely correlated to CD4+ T-cell count. However, activated CD8+ T-cell levels may be more closely related to viral load, and successful treatment with anti-retroviral therapy with resulting decrease in viral load has been associated with a concomitant decrease in activated CD8+ T-cells. Likewise, increases in CD4+ T-cell counts have been associated with a decrease in the level of activated CD4+ T-cells. In addition, co-infection in patients with HIV is also associated with CD4+ T-cell activation but not that of the CD8+ T-cell population. PMID: 15688282 Source: Regenstrief LOINC

Change Reason
Release 2.79: COMPONENT: Triggered by Coll w SCT: This is a specific fraction case where the denominator is percentage or /100. Because the logic is that the percentage piece is captured by Property: NFr (Numeric Fraction), and by Unit: %, therefore, it is redundant to include "100" in the component;
