How does lab test blood for TB?

Blood is not drawn for a TB test. There are two ways to test for TB. One is a skin test where they insert a bit of the TB under your skin and then in two days they read it. If there is no reaction you are OK. If there is a reaction a X ray of your chest is taken. As a teacher I am required by law to have a TB test every 2 years. Only once have I had a reaction to the skin test, so I guess I was exposed at some point, but the X ray showed that there was nothing.

If read too early or too late, the test may not provide reliable information regarding tuberculosis infection.


Is there a blood test to determine if I have tuberculosis?

Since 2001 there has been an approved blood test for TB that has advantages over the skin test, and is recommended by the US Center for Disease Control. Follow the links below for details. It does not require a repeat visit (if negative), and is more reliable in some cases, such as people who have had a TB immunization or multiple TB skin tests. It is called the QuantiFERON®-TB Gold test. Like the skin test, it only tells that a person has been infected with TB germs. It does not tell whether or not the person has progressed to TB disease. Other tests, such as a chest x-ray and a sample of sputum, are needed to see whether the person has TB disease. The test mentioned above tests for TB by detecting the immune response to TB. If a patient is severely ill, there may be TB bacilli in the blood, and a blood culture can be used.
