A positive skin test for TB means you may have been exposed to the TB bacteria in the past. A medication called INH, taken for 6 months, is recommended for those with a positive PPD reading (10mm of induration or greater) unless contraindication exists. The purpose is to treat the infection in its dormancy because there is a chance for disease reactivation in the future. For further information you can visit http://www.cdc.gov.
