As per FDA Bioanalytical method validation Guidance for Industry "All study samples from subject should be analysed in a single run, especially for studies designed with repeated measures from individual subjects(eg; crossover or sequential design required for BE studies)".
Can the study samples of same subject in more than single run for cross over design can be analysed i'e analysis of P1 samples and P2 samples can be carried out separately in two different runs? If yes, how it need to be justify to regulatory?
