If blisters are present (vesiculation), the test is also considered positive. In some groups of people, the test is considered positive if induration less than 15 mm is present For employees who are otherwise at low risk for TB and who are tested as part of an infection control screening program at the start of employment, a reaction of 15 mm is considered positive.
