late tester

late tester

A patient with HIV/AIDS whose immunity has already become severely impaired by the time the disease has been first diagnosed. This designation includes those who have a CD4 T-lymphocyte count of less than 200 cells/μL at the time of diagnosis and those who are first recognized as having HIV/AIDS because they have an AIDS-defining illness even though they did not seek medical care earlier.

According to research studies, the average CD4 cell count in late testers in 190, which is alarming low.
Using the date on which AIDS was diagnosed as supplied by state or local reporting systems, they defined participants as early testers (those who had had their first positive HIV test five or more years before the diagnosis of AIDS, or had gone five or more years without a diagnosis of AIDS after their first positive HIV test) or late testers (those who had had their first positive HIV test one year or less before the diagnosis of AIDS).
Since late testers are likely to have been HIV positive without their knowledge for an unknown period of time, the likelihood that further transmission of the virus to other individuals occurred is significant.
