This chapter is taken from the book Pharmaceutical Contamination Control: Practical Strategies for Compliance

A 'caveat' has been described as both a warning or caution, and a qualification or explanation. The word is used here with both meanings to help form a list of issues to have in mind when devising and performing tests for bacterial endotoxins. In its broadest sense the goal of such testing is to preclude the occurrence of significant levels of pyrogens from drugs, drug constituents, and drug containers/closures. Any oversight that impedes or lessens the likelihood of such preclusion or misjudges the levels that can be considered as ‘significant’ can be viewed as deserving of a caveat. Furthermore, any historical context or elaboration of test mechanism that broadens our views or deepens our understanding of the test deserves mention as well.
