Carryover Effect
The carryover effect is a term used in clinical chemistry to describe the transfer of unwanted material from one container or mixture to another. It describes the influence of one sample upon the following one. It may be from a specimen, or a reagent, or even the washing medium. The significance of carry over is that even a small amount can lead to erroneous results. Carryover effect in clinical laboratory Carryover experiments are widely used for clinical chemistry and immunochemistry analyzers to evaluate and validate carryover effects. The pipetting and washing systems in an automated analyzer are designed to continuously cycle between the aspiration of patient specimens and cleaning. An obvious concern is a potential for carryover of analyte from one patient specimen into one or more following patient specimens, which can falsely increase or decrease the measured analyte concentration. Specimen carryover is typically addressed by judicious choice of probe material, probe de ...

Carryover
Carryover may refer to: * Carryover effect, in automated analyzer * Carryover basis, in taxation * Carryover cooking * Carryover with steam Carryover with steam, in steam technology, refers to transport of moisture and impurities with steam. The moisture carryover with steam is quantified by the mass flow rate of liquid water per mass flow rate of steam. In boilers producing saturated ...
