What Is Tuberculosis?
9. Diagnosis
Your doctor will likely want to perform a physical exam to help look for signs of TB, or other diseases. A simple test has been developed that involves injecting a small amount of a certain substance beneath the skin. If the test is positive then it is likely the patient has TB, but the test is not always accurate.
Other tests involve taking a blood sample for examination. Sputum samples may also be taken that will help doctors look for signs of the bacteria. In some cases, imaging tests like CT scans or X-rays may be performed to look for signs that a tuberculosis infection is present.
