Dr. Nyambura Moremi, the Director and Quality Manager of Tanzania’s National Health Laboratory, has been suspended pending investigations.
The suspension comes a day after President John Magufuli questioned the credibility of coronavirus testing kits being used at the lab.
On Sunday, President Magufuli dismissed as faulty the coronavirus test kits used in Tanzania saying they had returned positive results on samples taken from a sheep and a pawpaw.
A statement from the health ministry said the minister has formed a committee of 10 people to investigate the conduct of the laboratory and submit the results by 13 May.
Testing for coronavirus will still be conducted at the laboratory. A team of experienced researchers has also been set up to investigate how the lab collects and tests COVID-19 samples.
Prof. Eligius Lyamula from Muhimbili University of Health and Allied Sciences will lead the team of nine researchers.
According to the most recent health ministry figures, which were published last week, the Tanzania has 480 confirmed cases of coronavirus, including 167 recoveries and 16 deaths.
