A tuberculosis (TB) skin test determines if you have TB germs in your body, says the Centers for Disease Control and Prevention. For the test, a harmless fluid is injected under the skin on the inside of your arm. A very small needle is used.

After a TB skin test, the CDC recommends:

• Do not bandage, lotion or scratch the spot.
• If the area itches, apply an ice cube or cold cloth.
• Return to your doctor 2 to 3 days after your TB test for a reading.

Even if your TB skin test is negative, you may still need more tests. If you have HIV or signs of TB — such as coughing, chest pain, fever, weight loss or tiredness — visit your doctor.
