Tuberculosis (TB) is a curable, infectious disease which usually effects the lungs (pulmonary TB). However tuberculosis bacteria can travel through the blood to infect other parts of the body (non-pulmonary TB).
Typically, pulmonary TB is infectious but non-pulmonary TB is not infectious. In order to become infected with TB a person requires prolonged, close contact with someone who has TB in their lungs and is coughing or sneezing the bacteria into the air.
Active and Inactive Tuberculosis
Inactive or latent TB occurs when a person becomes infected but the body's immune system is able to prevent the bacteria from making you sick.
Active TB disease occurs when the body's immune system is unable to stop the growth and spread of the bacteria resulting in illness.
Both inactive and active TB are treatable and curable.
TB treatment is free and is accessible through Region of Waterloo Public Health.
TB Skin Test
A TB skin test is used to screen for tuberculosis. A TB skin test indicates if you have been exposed to TB (if the germ is in your body). It can not tell if you have active or inactive TB. If the skin test shows that the TB germ is in your body, more testing will be done to determine if you have active TB disease.
One-Step versus Two-Step TB Skin Tests
A one-step TB skin test means that a test is placed and read 48 hours later to determine if you have been exposed to TB.
A two-step TB skin test means that an initial test is placed and read (in the 48 hour time frame) to establish a baseline. If the initial test is positive, no further testing is completed. If the initial test is negative, a second test is performed one to four weeks after the initial test and again read 48 hours later.
If a person has a documented two-step test, an additional two-step test never needs to be repeated.
Check your paperwork if you do not know if you need a one-step or two-step test. You can also call to check with the organization requiring the test.
