In order to get a result, you have to return 2-3 days after the test to have it read. And, if you didn't actually take the test, the place you paid for the test will have a record of this. A positive test result means you may have been infected with TB at some point. However, there are also a few exceptions. Millions of children are suffering from tuberculosis (TB) worldwide and often end-up with fatal outcome especially in resource-poor settings. The place you work at doesn't care if you have proof you took the test, they only care about the result of the test (which is proof enough). Ask your healthcare provider what your test results mean for you. Commonly we think it is negative when the lump is showing under 15mm. Tuberculin skin test (TST) is a conventionally used diagnostic test, less sensitive but highly specific for the diagnosis of clinical TB especially in undernourished children. However, we do not have any data on the role of TST positivity among the children who received nutritional intervention. Our aim was to examine the growth differences between TST-positive and TST-negative undernourished children aged 12 to 18 months who received nutritional intervention prospectively for 90 feeding days. Our further aim was to explore the determinants of TST positivity at enrollment. TB screening as one of the secondary causes of malnutrition was performed on 243 stunted or at-risk of stunting (LAZ score between <-1 and -2 standard deviations) children in a community-based intervention study designed to improve their growth parameters. Differences of growth between TST-positives ( n = 29) and TST-negatives ( n = 214) were compared using paired samples t-test and multivariable linear regression from anthropometric data collected before and after nutritional intervention. Multivariable logistic regression was used to find out possible predictors of TST positivity using baseline sociodemographic data. Of the 243 children screened, 29 (11.9%) were TST-positive and 11 (4.5%) had clinically diagnosed pulmonary TB. A health care worker will use a small needle to inject testing fluid (called tuberculin) under the skin on the lower part of your inner arm. Statistically significant improvement of LAZ and weight for age Z-score (WAZ) were observed among the TST-negative participants at the end of intervention period ( p = 0.03 for LAZ and p = 0.01 for WAZ). The TB skin test, also known as the tuberculin skin test, may be used to find out if you are infected with TB germs. If you have a negative TB skin test reaction, you probably do not have latent TB infection. #Normal negative tb test pictures skin# Negative - usually refers to a test result.
