QFT Access Usability (Ellume) Qualitative Study

Usability of the ACCESS QuantiFERON® TB platform for the diagnosis of Tuberculosis infection in a low-resource setting with high TB prevalence


QFT access usability study was an observational study embedded in the ongoing TREATS study in Zambia to evaluate the usability of the QFT access system for the detection of TB infection in 100 participants in a total of 6 laboratories, (the Zambart Central laboratory and 5 regional laboratories).

QFT access system is a simpler version of the QFT-plus, easy to use, with assay processing and read-out requiring shorter time, no laboratory needed and tailored to the requirements of low resource regions with high rates of TB. QFT access has the potential to be a scalable solution for low-resource, high-burden areas for early screening of TB infections, which can lead to more effective treatment and containment in these settings.

The TREATS infection cohort provided a unique platform within which to evaluate its ease of use and potential to improve TB control in regions with limited infrastructures.

Data collection was from October 2019 to November 2019
