End-user errors in applying two malaria rapid diagnostic tests in a remote area of Sudan.

We assessed end-user practice for numerous procedural steps of two types of RDTs: Core Malaria Pf (the cassette format) and OptiMAL IT (the dipstick format). Two types of errors occurred: generic errors common to both types of test and specific errors caused by the test design and manufacturer's instructions. End-user errors were more frequent with OptiMAL IT than Core Pf tests.
