It doesnât mean that there is no virus present, but that the amount is so low that the test cannot measure it. As HIV disease progresses, the viral load count tends to rise, so that someone who starts with a very low viral load count (say 5,000 copies of virus per drop) may rise to a very high viral load count (say, several hundred thousand or even more than a million copies of virus per drop of blood).
