What are the different types of reagents used for COVID-19 Test Kits?

HDIAC provided supplementary analysis to a DSIAC inquiry concerning different types of reagents used for COVID test kits. Research into different types of testing and collection methods was conducted, including antigen and antibody tests, reverse transcriptase polymerase chain reaction (RT-PCR) tests, point of care (POC) tests, saliva tests, and nasopharyngeal tests. Analysts then compiled a list of all equipment and chemical reagents used in each of the seven given FDA-approved test kits provided in the inquiry. HDIAC analysts also provided a summary of the necessary conversion processes from RNA to DNA required for polymerase chain reaction (PCR) tests – the most common type of SARS-CoV-2 test. Finally, HDIAC provided up-to-date information involving RUCDR Infinite Biologics’ saliva test, quoting recent studies of the like that support the statement that saliva-based testing will increase testing capacity yield.
