Explanation

Your T cell count is the number of 'HIV clones' vs 'T cells' in a single drop of your blood. The number of HIV clones is your viral load. A high viral load is bad, but a high T cell count is good. If you don't have HIV, your T cell count is about 1,500 cells per drop of blood, but if you have HIV, the number of T cells goes down by 100 cells per drop of blood every year.
