Negative result: If you have ever been exposed to TB (by having it yourself or being close to someone who has), then your body will react to the TB skin test and make a big bump. The fact that your body didn't react means that you have never been exposed to TB and is a negative result! Have a medical professional read the result 48-72 hours after the TB test was applied!
