Health officials estimate 20 percent of the one million people infected with aids in this country don't know they're infected.
This week, the American Academy of Pediatrics has released new guidelines suggesting every teen, age 16 or older, get an HIV test.
The group says it will prevent an infected teen from unknowingly spreading the disease, and send a message to those who test negative.
Dr. Dan Kelly said, "When it comes back negative they're relieved. They've had that message that it's serious business."
Some parents are worried the pediatric group's recommendation goes too far, and AIDS groups are hoping this will be the first step in making AIDS testing routine for any physicians visit.
