Interpretation & Reference
Carry over effect is calculated using the equation:
Carry Over = (L1 - L3) / (H2 - L3) × 100
"q" may also be called the 'carry-over ratio', and is sometimes expressed as a percentage value. It implies that the influence of carry-over effects on the analytical results is inversely proportional to the concentration difference of the component to be detected by the analytical procedure in the two specimens.
Carry-over within a particular procedure is of interest. It is dependent on the method, including all reagents applied. Therefore, carry-over effects, rather than carry-over itself, need to be determined. For this purpose, a sequence of specimens, usually with high (a) and low (b) concentrations of the analyte to be measured, are processed — for example a1, a2, b1, b2, b3.
