Detection Risk (DR) is the risk that the auditor will not detect a misstatement that exists in an assertion that could be material (significant), either individually or when aggregated with other misstatements.[1] In other words, the chance that the auditor will not find material misstatements relating to an assertion in the Financial statements through substantive test and analysis.[2] Detection risk results in the auditor's conclusion that no material errors are present where in fact there are. It is a component of audit risk.
Detection Risk and quality of audit have an inverse relationship: if detection risk is high, lower the quality of audit and if detection risk is low, generally increase the quality of audit.
