My tb result looks over 15 mm vertically and exactly 15 horizontally. it is not red but only slightly pink, no boils, still is soft and even positive?

TB Skin Test: The size of the induration is the most important to examine 48 to 72 hours after administration of a PPD (tb skin test). An induration of 15 mm is considered positive for TB but may also be indicative of a prior bcg vaccination, commonly encountered in many non-us born individuals. Various factors such as signs & symptoms of TB and prior exposure will help determine need for treatment.
