A theoretical study of carryover in selective access analysers.

Carryover in selective access analysers is of two types: physical (specimen) and chemical (reagent) carryover. There are four constants describing carryover of each analysis: s, the batch carryover constant; k, the interaction constant; m, the slope constant for reagent carryover; and C, the intercept constant for reagent carryover. Procedures to measure these constants are described, and equations to allow correction of results for specimen and reagent carryovers in computer supported instruments are developed.
