|
The AUCpeo, that is, percent area obtained after extrapolation from Tlast to infinity is calculated by using the formula AUCpeo = 100*(AUC[0-inf] minus AUC[0-last])/AUC(0-inf).
This parameter provides information about what percentage of the theoretical curve AUC(0-inf) is possible to determine experimentally (AUC0-last).
