However, these false positives will be evaluated further and refined in the light of alternative information. A similar procedure is applied in DNA or fingerprint database searches where one expects the system to return a ‘‘hit’’ result if the donor is indeed recorded in the database (the opposite would comprise integrity). It is expected and accepted that the system returns a list of candidates which most probably contains some false positives. In such cases, the focus is generally placed on integrity rather that credibility, even if an adequate balance must be struck depending on the context of any database search.
