Good clinical practices in the bioanalytical laboratory

Abstract

Despite the existence of good clinical practice guidelines, the way in which they are applied to the bioanalytical laboratory remains unclear. Aspects of patient confidentiality, informed consent and subject withdrawal; addressing unblinding associated with sample analysis, including repeat analysis and incurred sample reanalysis; or the differences in responsibilities between the sponsor and contract research organization are not articulated by the US FDA within the bioanalytical setting, and for most bioanalytical laboratories this remains a gap in their standard operating procedures. The aim of this article is to identify and clarify the aspects of the good clinical practices that are applicable to the bioanalytical laboratory when conducting bioanalysis with clinical samples, and to address potential gaps in the bioanalytical laboratory when it comes to clinical sample bioanalysis.
