Waived testing options for FLU+SARS

We currently use the Sofia 2 for FLU+SARS Antigen FIA testing.  I oversee 2 outpatient clinics that use this product, and it is grouped together under an agreement for our Medical Group offices.  Our medical group is going to be transitioning to a different platform at the beginning of the year.  With the 2 clinics I oversee that use this test, I don't believe we will be able to meet the volume requirements to maintain the current agreement and therefore there will be pricing differences and new terms.  I was just looking to see what else everyone was using that was waived, and a good fit for small volume offices that tests for FLU+SARS as a combo test.  We may stick with the Sofia 2, but just exploring all options. My email is aholland@catawbavalleymc.org if you prefer to respond via email.  

Thanks!
