Such cutoffs shall be consistently applied for all saliva testing using that test system. All confirmations shall be by quantitative analysis. Concentrations which exceed the linear region of the standard curve shall be documented in the testing facility record as "greater than the highest standard curve value."

(b) All confirmation testing on saliva shall be performed on the same specimen that was identified as positive on the initial screen.
