    CD4:CD8 Ratio Profile

    HIV-1 infection results in a decrease of CD4 T cells, an increase of CD8 T cells, a decrease in the CD4:CD8 ratio, and a progressive destruction of immune function. In HIV-1 seropositive patients, enumeration of CD4 T cells may be used for prognostic purposes and to monitor disease progression and antiretroviral therapy. Also Known As: HIV disease progression & treatment monitoring

    Cytomegalovirus (CMV) IgG

    Intrauterine or congenital CMV infections occur in 0.5 to 2.2% of all live births. Symptomatic congenital infections usually occur in infants born to non-immune mothers who have primary infections during pregnancy. A single positive CMV IgG result is and indication of present or past infection. The presence of CMV IgM suggests a recent CMV exposure.
