Hi there and thanks for using the AIDS Vancouver online helpline as your source of HIV/AIDS related information.
 
To answer your question, we must first distinguish between ELISA and Rapid testing, since there are small differences between them. ELISA testing methods use a blood test to search for the presence of HIV antibodies, and require a laboratory to perform the investigation. Rapid testing also detects HIV antibodies, though can be performed on either blood or saliva, and does not require a laboratory (can be performed at the point of care). At 12 weeks, ELISA testing has an accuracy of 99.8%, and Rapid testing has an accuracy of 99.6%. However, a negative result at that time can be considered conclusive, as long as there are no complicating factors such as a preexisting immunodeficiency, or current antiviral treatment. Positive results, regardless of ELISA or Rapid testing method, are generally flagged for further confirmatory investigation, in which case an additional blood draw may be needed.
 
I hope this helped to answer your question, and please do not hesitate to ask if you have any further questions.
 
Regards,
 
Jonathan
