What is the control factor number "K" displayed on the DR1900 when using TNT+ or LCK reagent vials?
DR1900 control factor
The DR1900 does not read the barcode label on the TNT+ or LCK vials like the DR3900 and DR6000. The control factor should be confirmed to match the factor provided on the reagent packaging. Inaccuracy in the measurement may result if the control factors do not match.
