Study Design, Site and Archival Sample Selection
Criteria
This study was an experimental retrospective study of archived CoViD-19
rRT-PCR samples. Ethical approval was sought and obtained from the
University for Development Studies review board (UDS/IRB/115/22). Three
packets (75pcs) each of DG Rapid,
SD Rapid, and SS Rapid were randomly sampled from the Ghanaian market.
The study was conducted at a Food and Drugs Authority/Health Facilities
Regulatory Agency (FDA/HeFRA) registered SARS-CoV-2 rRT-PCR testing
facility in the Greater Accra Region of Ghana, between June 2022 and
July 2022. The eligibility criteria for this study involved using
clinical samples that were previously tested for COVID-19 using the
rRT-PCR technique. However, samples which are insufficient, inadequately
labelled, or other sample quality issues were excluded from the study.
There were no restrictions on age, gender, or ethnicity.
