Cholesterol and blood sugar are routine tests offered at doctor's offices, but HIV testing may soon be added to the list.
The Center for Disease Control says all patients age 13 to 64 should be screened for HIV when they receive medical care, regardless of their risk for the disease.
People who are unaware of their HIV status cause between 50 to 70 percent of new HIV cases.
Some doctors worry the people who need the test the most are being missed.
"They don't have access to healthcare, they don't have insurance or money for one or a number of reasons they don't get regular checkups," says Margaret Gradison, M.D. of Community and Family Medicine.
The test would be voluntary, so patients can refuse to be screened.
The CDC says early detection will give patients the best chance at treatment.
Right now, nearly 40 percent of cases are detected within one year of progression to full-blown AIDS.
