This briefing covers the need for new TB diagnostics, the use of technology to improve TB diagnostics in Zambia, and the implications for policy and practice.
New diagnostic tools currently being tested by the ZAMBART project include:
- The use of various liquid culture TB laboratory tests to examine the feasibility and accuracy of rapid TB specimen tests in a resource-limited setting;
- The use of a digital chest x-ray machine which utilizes a computer-aided diagnostic (CAD) tool for reading chest x-rays to help diagnose TB in areas where there is no radiologist;
- The use of containerized TB laboratories in large-scale TB prevalence surveys.
Each of these different technologies is aimed at streamlining and improving the patient-provider interaction and allows for more accurate and timely specimen analysis.
