If you have not been exposed to TB the test will always be negative. New people to health care do what is called a two step PPD. one week the left arm the next week the right arm, this way if they have ever been exposed to TB in their life it will show up. Depending on if you travel outside the United States and which country you may visit it is required to have a PPD when entering back into the United States at least in the state where I live. So, if you have never been exposed the test will always be negative.
