Field sampling and testing projects are carried out by WHO in order to:
monitor the quality of medicines (both WHO-prequalified and non-WHO prequalified medicines) procured by UN agencies
contribute to national quality control of medicines and
contribute to strengthening of health systems and capacity building by cooperation with national medicines regulatory authorities (NMRAs).
Projects are managed according to a pre-established protocol with defined study objectives. Samples are collected by NMRA staff and tested by WHO-prequalified laboratories, if available, or by laboratories whose test results have been proven to be reliable. Results obtained are discussed with the NMRAs of the participating countries before publication.
Quality monitoring reports
Three reports summarizing the findings of quality monitoring projects carried out under the auspices of WHO prequalification are available, relating to:
- anti-tuberculosis medicines circulating in selected newly independent states of the
former Soviet Union (2011)
- selected antimalarial medicines circulating in six countries of sub-Saharan Africa (2011)
- antiretroviral medicines circulating in selected African countries (2007).
