$SRNE COVI-TRACE is still the best in class saliva test. The one from iAbra called Virolens which is backed by UK government requires a lab to analyze saliva samples, COVI-TRACE doesn’t. There are also close competitors such as the one from Roche, Abbott, and Oxford (Nanopore) that when compared to COVI-TRACE still comes in second. It is also very important to know about manufacturing capabilities that even with a direct competitor ours can still beat in scale. Nonetheless, there will always be a demand and enough room for rapid saliva test in the market today.
