In scientific papers what does it mean if a viral load is reduced to 0.93log10 copiesul More specifically what value does 0.93log10 convert to?

Answer 1

0.93log10 copies per ul (microliter) corresponds to 8.5 copies per ul or 8500 copies per ml. The number is based on powers of 10. This is because 100.93=8.5. So 1 log 10 is 10 copies, 2 log10 is 100 copies, 3log10 is 1000 copies and 6 log10 is 1,000,000 copies. It is reported this way because any treatment needs to show a drop in viral load by a factor of 100s or even 1000s to be effective.
