摘要

For more than 90 years the best test available to identify people with TB infections has been the tuberculin skin test (TST). This test requires intra-dermal injection of purified protein derivative (PPD) derived from the TB bacteria followed by observation of the injection site by a trained skin test reader between 48 and 72 hours after injection. Two clinical visits are required in a 72 hour period and for many petroleum workers in remote locations (precisely those areas where TB prevalence is highest) this is impractical. As a result, many workers who have skin tests are advised on how to “self-read” the results – a practice without any proven reliability or validity. Self-assessments of tuberculin test results, if accurate, could enhance tuberculosis screening efforts by reducing the need for follow-up visits for skin test reading (1). The TST also has other limitations, including false positive test results in individuals who were vaccinated with BCG and in individuals who have infections not related to Mycobacterium tuberculosis (2), digit preference by TST readers, and false negative results in people with immune systems disorders like HIV, diabetes, and those on treatment with systemic steroid medications.
