Welcome to EmpowHER. Having Zero MM, is most likely you do not have TB. Immigrants who have moved from a country with a high TB rate in the past 5 years are considered positive 10MM or higher. This is not a perfect test. Up to 20% of people infected with the bacteria that cause TB may not have a reaction on the PPD skin test, but that can be due to certain conditions that impair the immune system (cancer, recent chemotherapy, late-stage AIDS) may cause a false-negative test result.
