What are the measurements of the induration? What are my risk factors for TB infection? What is the interpretation of my test? Do any follow-up tests need to be completed? Are there any precautions I need to take after receiving this test result?
Use of a pen to demarcate the boundaries of induration on the skin can help produce more precise measurements, but reading skin tests is inherently variable and subject to a number of errors, including terminal digit preference, that is, a tendency to favor recording 5-, 10-, 15- and 20-...
Integrating these measurements has shown systematic relationships between serum metabolites and blood transcript levels in various signaling transduction, candidate transport, and metabolic processes (Bartel et al., 2015). Duffy et al. combined Zak's TB prognostic signature (Risk16) (Zak et al., ...
The measurements of success in the TB world are often framed in terms of coverage of diagnosis and treatment. Yet coverage, or in the language of the International Covenant on Economic, Social, and Cultural Rights (ICESCR), availability, is only one aspect (and the bare minimum) in the broa...
[37] worked on determining and comparing the sensitivity of the IGRA and tuberculin skin test (TST) separately and as a com- bined approach in active TB patients. The TST induration measurements was understood by making use of two cutoff points: ≥ 5 mm (TST-5 mm) and ≥ ...
In the assignment of initial QFT values and the distribution of within-subject variability, our analysis relied heavily on data from the largest study of IGRAs in North American HCWs [8]; however, this study collated QFT measurements from lab- oratories employing potentially diverse methodologies. ...

Tuberculin skin tests (TSTs) and QFTs were performed at baseline and after 2 years of follow up. Half of the participants had TST and QFT performed at additional time points. Participants were observed for incident tuberculosis disease for up to 5 years. MEASUREMENTS AND MAIN RESULTS: Among ...
CAUTION: Because temperature measurements are critical in determining if the Therabath® unit is operating correctly, it is important that you use a calibrated thermom-eter and that you have the calibration of the thermometer periodically checked. ...
