Precision
When this kit is used for extraction from the in-house precision reference CV for 10 replicates, the coefficient of variation (CV, %) of Ct value is not more than 10%.
Inter-batch difference
When the in-house precision reference is tested on three batches of kits under trial production upon repeated extraction and, the coefficient of variation (CV, %) of Ct value is not more than 10%.
