The health directorate has asked all private Covid-19 testing laboratories to stop running sample collection booths outside hospitals that have been set up for outgoing passengers to foreign destinations.
"The allegations of providing fake Covid-19 certificates and charging additional money through cheating people have been proved in the primary investigation," said a circular signed by Dr Farid Hossain Mian, director of hospitals and clinics at the directorate today.
The other directives include: samples of the outbound passengers cannot be collected from home in any situation, the main passport must be scrutinised and the form should be filled up with the passport number exactly during the test, and no chance for re-testing passengers who were tested positive within seven days.
Other than that, passengers who test positive seven days prior to the journey must be tested through government testing labs.
Activities of any RT-PCR lab will be suspended if there is any allegation against it.
