Why doesn’t Eve Technologies run a standard on each Discovery Assay?

When Eve Technologies runs a routine cytokine array, the same kit lot number is purchased in bulk and upon the first assay session that uses that kit lot a standard curve is run in duplicate.  This standard curve is continued to be used through-out the use of that lot.  Every assay of that lot is run on the exact same machine and the machine is calibrated everyday with highly specified and stable calibrators.  To ensure consistency and quality, Eve Technologies runs a QC sample with every assay and these QCs are tracked with implementing Levy Jennings (as required by CLIA).
