The aim of this study is to assess the clinical performance (sensitivity, specificity, positive and negative predictive values) of the STANDARD™ Q Malaria/CRP Duo Test when used by health care workers (HW) in a point of care (POC) setting in malaria endemic areas in India. Performance will be assessed in comparison with expert microscopy as the reference test for malaria, and with a high quality, commercially available C-Reactive Protein (CRP) test kit run on a laboratory machine as a reference test for CRP.
