If I'm reading this correctly (combined with a review of Discern's website), the MI assay is one of three assays offered by Discern/SynapsDx. The other two are the PKCe assay and the AD index assay, but this PR specifically relates to Discern's "primary assay", the MI assay. No information (at least here) that the PKCe assay is being used, is accurate, etc.
