Concordance between tuberculin skin test and interferon-γ assay and interferon-γ response to mitogen in pediatric tuberculosis contacts. 2008;40(8):629–34. CAS Hopefully there's more privacy for kids now and the bum or leg would be an option. Chest X ray changes were seen in 25/368 QFT positive and in 2/394 QFT negative children.

In answer to the question, it's almost certainly about speed and privacy. Preventive chemotherapy was offered if Quantiferon was positive. The absorbance was measured in Vmax Kinetic Microplate Reader (Molecular Devices, USA) and the optical density (OD) values were evaluated using the QFT®-TB Gold Analysis Software version 2.50. One mL blood was collected into each of three different collection tubes, which include Nil Control tube, TB Antigen tube, and Mitogen (positive control) tube. PubMed 2015;61:960–2. The diagnosis of latent TB in health examinations with no known exposure should not be based on a large TST alone but preferably on a combination of TST and QFT. The median TST diameter was significantly larger in QFT positive than in QFT negative children but the overlap was great, so it is not possible to predict the result of QFT based on the size of the TST diameter in the individual case, which agrees with two previous studies of Turkish adults and of immigrant children in Norway [27, 28]. The evaluation of BCG scar was made before the QFT result was known. Clin Infect Dis.
