Thanks Helmut,

Do you consider 1ng/mL LLoQ sufficient with the current state of art equipments? I think it's too high (Sciex 5500+ can do better).

With the drug I am working with, based on pilot data, will be like 120 ng/mL for Cmax (the highest Cmax, the study was 200 mg so assuming 2x200mg). The range now is 1ng/mL - 200 ng/mL. I think I can push down the ULoQ to 100 ng/mL and do dilution for higher conc samples.

John
