Explanation:

Recently, U.S. Food and Drug Administration (FDA) have granted an Emergency Use Authorization for SalivaDirect, a saliva-based test for COVID-19.

• It has been developed by researchers at the Yale School of Public Health in collaboration with the National Basketball Association (NBA).
• It is an RT-PCR based test. Collecting and testing saliva samples involves three steps: collecting saliva without preservative buffers, proteinase K treatment and heat inactivation, and duplex RT-qPCR virus detection.

Hence both statements are correct.
