Tuberculin Skin Testing in Children

In 1996, the American Academy of Pediatrics (AAP) recommended targeted tuberculin skin testing (TST) of children while discouraging routine TST of children without risk factors for tuberculosis (TB). Recent studies have provided evidence in support of the targeted TST and recommendations that favor risk assessment over universal screening with TST. While evidence for targeted TB testing exists ...

The Booster Phenomenon of Tuberculin Skin Testing in Patients Receiving Hemo-dialysis

Background: The risk of developing tuberculosis is high among chronic hemodialysis patients. The tuberculin skin test (TST) has been in use for diagnosing latent TB, but few data are available on TST in hemodialysis patients. Objective: This study was done to identify the TST reactivity and frequency of booster effect in serial TST among hemodialysis patients. Methods: A total of 100 patients i...

Tuberculin skin testing in the era of multidrug-resistant tuberculosis.

Transmission of Mycobacterium tuberculosis undetected by tuberculin skin testing.

RATIONALE The development of tuberculin skin test (TST) positivity following infection by Mycobacterium tuberculosis is not invariable and may depend on bacillary as well as host factors. OBJECTIVES First, to compare the diagnostic performance of the TST and a form of in vitro IFN-gamma release assay (IFNGRA) in the circumstances of a contact investigation prompted by an unusually severe inde...

Results of a tuberculin skin testing survey in Albania.

INTRODUCTION Tuberculosis affected about 8.5 million patients in 2011. Numerous efforts are needed to reduce the pool of individuals with latent TB infection (LTBI). The aim of the study was to describe a tuberculin skin testing (TST) survey carried out in Albania to estimate the LTBI burden; furthermore, knowledge of TB was evaluated through an ad hoc questionnaire. METHODOLOGY A TST survey ...
