The benefits of innovative diagnostic tools for neglected tropical diseases: A scoping review

Vulnerable populations all around the world, especially those in low-resource settings, continue to suffer the consequences of neglected tropical diseases (NTDs). Methods of diagnosis that are considered traditional are frequently insufficient when it comes to the successful identification and management of NTDs related issues. This study examines how novel diagnostic technologies improve diagnosis accuracy, accessibility, and cost-effectiveness for NTD management. In carrying out this review, a scoping review was adopted using PubMed and grey literature sources. The search yielded 336 articles, of which 23 were selected through title and abstract screening. After reviewing the complete text, 9 studies met the eligibility criteria for inclusion. New diagnostic techniques like rK39 and rK28 NTDs, molecular diagnostics, and point-of-care testing showed better sensitivity, specificity, and accessibility than older methods. Studies also showed that they might be used in the field to improve disease surveillance and treatment uptake, especially for visceral leishmaniasis, schistosomiasis, and lymphatic filariasis. The use of innovative diagnostic technologies is very helpful for controlling NTDs because they make it easier to get accurate diagnoses in places where resources are limited. Subsequent study must concentrate on the expansion of these technologies, the resolution of infrastructural constraints, and the investigation of their contribution to global efforts in the eradication of NTDs.
