cd4: what is the lowest, what is the highest? what is the okay point?

viral load: what is too high? what is undetectable?

how are these things measured? per every cm2 of blood??

"Understanding Your T-cell Test" <-- This page also talks about percentage so be sure not to skip that part. It's important
"Understanding Your Viral Load Test"

A normal CD4 starts at 400-600 depending on which country you're in (for example in India 400 is bottom limit of normal on a population level) and your gender. 300 or more is functional.  200 or less is starting to get non-functional and puts you at greater risk of opportunistic infections.  200 is the lowest level doctors recommend you let your CD4 count fall to before stating treatment. 

In % terms, a normal CD4 % (CD4 cells as a proportion of all lymphocytes) starts at 30-40%. A CD4 % of 13% roughly equals a CD4 count of 200.  This is important to note cos you can have a CD4 % of 13% and have a higher CD4 count.  CD4 count varies by time of day etc so the % may be a better long-term indicator of what your CD4s are doing.

A viral load of 50,000 to 100,00 (log 4.7 to 5) is considered high.  A viral load of 50 (log 1.7) or less is considered undetectable.

Both CD4 and viral load are measured per millilitre (mL) or cubic millimetre (mm3) of blood.
