Bioequivalence and Bioavailability Forum

Hi All,

I want to know if there is any guidelines that talked about what to do if whole one period concentrations (Test or Reference) was zero.

I know statistically that in such case, the whole period or subject is deleted. But I am looking for a reference or guidelines for that.

I know that there is a guidelines talking about the reference and also the test in very low conc. However, my case is that the test is Zero not very low conc.

Thanks.
