Q and A


What does viral load test info mean?

My viral load blood test result says: “The linear range of this essay is 150 – 10,000 copies/mL (2.16 – 7 log copies)”. 

My cd4 count 928 but i don’t know what it means



This sentence just gives the range of sensitivity for the viral load test: it can measure from 150 to 100,000 copies/mL.

If your results i undetectable, it means that your result is less than 150 copies/mL

This link explains how numbers are converted into “logs”:


Your CD4 count is very good because it is higher than 500 cells/mm3.

    Hi Simon

    I just tested positive with a 258000 viral load. What’s my cd4 count from these numbers? My testers weren’t clear on this part.
