Is there a further >test which can identify the difference from real HIV infected cells? There are such tests but they are harder than the usual anti-body test for HIV. Probably the most accurate (though it is not without dispute) is the polymerase chain reaction which will test if there is RNA with the pattern of [part of] the genetic code of the virus. This is how the presence of HIV in a British sailor who died in the 1950's was detected. The possible difficulty with this is that it does not demonstrate infection with the virus - only the presence of the virus and there is some dispute therefore that it correctly indicates the time in which a person can have an active HIV infection but not be sero-positive for HIV antibodies. -- Rolfe G.
