In a statement issued on Wednesday evening the Ministry admitted that they did not declare positive cases on the 23rd of May because they did not believe the sudden change of figures to double digit figures.
Read the full statement below:
We report the results of PCR tests conducted using the GeneXpert machines which were done over the past four days which had not been included in the situation report as we awaited confirmation of the results from the National Microbiology Reference Laboratory.
This confirmation was required because of the unusual surge of positive tests after the introduction of the cartridge based nucleic acid PCR (GeneXpert).
For Quality Assurance purposes, environmental sampling, inter-lab comparability and resampling of patients was done.
Environmental sampling (swabbing of the laboratory) was conducted to rule out any possible laboratory contamination. This was carried out due to the surge in positive samples after the introduction of GeneXpert testing in all the provinces.There was no contamination identified.
Inter-lab comparability: The same positive specimens were sent to other labs in the country mainly National Microbiology Reference Laboratory & National Virology Reference Laboratory to check for concordance and there was 100% concordance
Resampling of Patients: A sample of the positive cohort was resampled and retested and the results were in agreement with the initial results
