Hi Helmut,

This just popped into my head (flashback... Nightmare, whatever you called it)...

Should the lab adjust the concentration profile to remove the residual levels caused by the pre-dose concentration???? ie. using the t1/2 and determine the amount of pre-dose concentration remaining throughout the timepoints and subtract it from the respective concentrations.

I remember one lab doing this and they said it's part of their SOP...

Thanks

John
