<strong>of</strong> such testing requirements and guidelines as described in this article. In general, harmonized standards and guidelines augment the confidence level in a safety assessment procedure, wherever it is conducted. The endeavor in all safety assessment, as in all scientific investigations, is toward good scientific practices and rationale that will be applied toward protecting the population. The rest <strong>of</strong> the details will generally fall into place on their own. REFERENCES 1.
