It is an old paper of 2005, Low Levels of
Human Immunodeficiency Virus Type 1 DNA in High-Risk Seronegative Men, that describes several people who seroconverted many years after they are identified HIV DNA positive. These people are likely elite controllers, who suppress virus under an extreme low level that doesn't trigger anti-bodies. During the past 4 years, I have some antibody and RNA tests, and both negative, but I have a high CD8+DR percentage continually.
