RegisterInterference Peak [Bioanalytics]
Dear Group Members,
During subject plasma sample analysis by LC/MS/MS, an extra peak (possibly due to metabolite) is observed which is not completely separated from the drug peak. But Method Validation was performed without the metabolite (as per OGD communication) & there was no interference peak during method validation. In such a situation, how should the analyst proceed with subject sample analysis?
Thanks & regards,
Dr. Harish L. Rao
