Non-detectable viral load

Jul 28, 2000

What is considered a non-detectable viral load? Mine went from 40,000 to 70 after 7 months of being on Combivir and Viracept, and I read that when your viral load is less that 400 it is considered non-detectable. That is why I ask the above question.

Response from Dr. Holodniy

Depends on the generation of viral load assay. First generation assays have a lower cutoff of 400-500 copies/ml. Newer ultrasensitive assays have a lower cutoff of 50 copies/ml. Currently we consider < 50 as "undetectable.
