A lack of simple, inexpensive, and rapid diagnostic tests for febrile illnesses
other than malaria leads to overtreatment with antibiotics for those who test
negative for malaria, and contributes to the global rise in antimicrobial
resistance. New tests for the detection of host biomarkers provide promising
tools to differentiate bacterial from non-bacterial infections in febrile
patients. However, most available biomarker tests are not currently used in
resource-limited settings, and very few evaluations have been performed in low-
and middle-income country populations with non-severe febrile illness. As a
result, our knowledge of the performance of these tests in settings with high
prevalence of infectious and poverty-related diseases such as malaria, HIV,
malnutrition and intestinal parasites is poor. This paper describes challenges
faced during the process of getting to an approved test, including difficulties
in selecting the most appropriate fever biomarkers; suitable study designs and
sites for test evaluations; lack of available reference tests to evaluate the
performance of new tests; and lack of clear regulatory pathways to introduce such
tests. As many new biomarker assays are in development, understanding these
challenges will better enable those working in this area to address them during
product development.
