hello...most people find this term a bit confusing, especially as doctors often don't explain what it means! Basically, it's just a sort of "shorthand" way of describing large changes in viral load measurements.

here is a link to a really useful little table, which helps you to work out log reductions / increases...and also tells you exactly what it's all about!

hope that helps  :)

One log reduction is equal to a 10 fold decrease. A 1 log decrease is the same as going from 1,000,000 to 100,000 or 10,000 to 1,000 etc

If you wanna convert your viral load into a log value just go to Google and type "log(#number goes here) into the search box (then hit return) eg typing in "log(50)" gives you the result "log(50) = 1.69897" (the log value for 'undetectable').

Thank you, mat and HIV worker! So...one log reduction is taking off a zero. And one log reduction is equal to 10 fold. Its easy.
