Most physicians are unable to use clinical skills to differentiate those who should and should not be tested for HIV infection.

During the period of early HIV infection, past research showed that 50 to 90 percent of patients develop one or more of the following symptoms: fever, nausea/vomiting, weight loss, rashes, oral ulcers, and swollen lymph glands. While identifying HIV infection early can greatly contribute to reduced mortality and the likelihood of further HIV transmission, these symptoms are too non-specific for physicians to recognize, whereas the absence of symptoms does not reliably exclude infection.
"This study is not meant to be critical of physicians because of the limitations of our ability to discern who should and should not be tested for HIV infection," says Dr. Evan Wood, lead author and Canada Research Chair in Inner City Medicine at the University of British Columbia Faculty of Medicine. "Rather, this study highlights the importance of routine HIV testing, just like we routinely test for other health conditions."
