Sub-Saharan centralized biorepository for genetic and genomic research.

Quality-assessed biomedical samples are essential for academia- and industry driven research on human diseases. The etiologies and the molecular genetic factors relevant in African diseases, including both infections and complex degenerative diseases as well as cancer, need to be studied using well annotated and well-preserved biosamples acquired from native African ethnic groups and compare the results with non-African populations and/or with Afro-Americans. However, a number of difficulties negatively impact on the possibility to obtain clinically annotated biological samples in most Sub-Saharan African countries.

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.
