Intensity of the Internal Standard Response as the Basis for Reporting a Test Specimen as Negative or Inconclusive by Liu, Ray H., Wu, Chih-Hung, Chen, Yi-Jun, Chang, Chiung-Dan, Linville, Jason G., Canfield, Dennis V.

“…Under normal circumstances, a test specimen is reported as “negative” when the response of the analyte is absent. However, if the intensity of the internal…”
