Not knowing any of the treatment history it's hard to comment. However, a CD4 cell change from 18 to 8 is not significant. Cells are measured in # cells/mm3, or in percentage of CD4 cells. Likewise at such high viral load levels, a change from... Read more »

What does viral load mean on a cellular level?

I understand that the viral load test measures the amount of virus in the blood. Does this mean that a higher viral load causes the DNA in more cells to be affected at once? Is having a viral load of 8,000 for four years the same as having a...
