| 33 | The figures are illustrative of the shape of the relationship rather than exact, and the exact values follow from the binomial distribution and the sampling plan. The point is that end-product sterility testing detects gross failure reliably and low-level failure poorly, which is why it functions as a final check on a validated process rather than as the basis for release on its own.{{r|usp1211}} | 33 | The figures are illustrative of the shape of the relationship rather than exact, and the exact values follow from the binomial distribution and the sampling plan.

| + | 36 | Lyophilised research peptides are not manufactured as sterile products, are not filled aseptically, and are not tested for sterility as a matter of course. A certificate for such material would not ordinarily carry a sterility determination, and its absence carries no implication.{{r|usp1503}} | |

| + | 38 | Where a sterility statement does appear on a research-chemical certificate, the questions that make it interpretable are which method was used, how many units were tested, and whether method suitability was demonstrated. Without those, the statement is not connected to any defined level of assurance. | |
