Difference between p24 and viral load

May 15, 2004

Dr, what is the difference between a viral load and an antigen test, since both of them measure the virus itself?

Why a p24 with an negative eliza is not 100% sure whilw a negative viral load and a negative eliza are 100%..

Please answer.

Response from Dr. Holodniy

A P24 antigen test measures the concentration of one protein that the virus produces during active infection. Viral load measures the amount of HIV RNA (nucleic acid) not a protein. Thus, they measure two different things or aspects of the virus.
