It is likely that the discrepancy is an inventory or clerical error and not truly missing samples.

It was a clerical error in the transcription of numbers.

It's fairly unusual that we would do this.

We think that at the end of the day, it's going to be basically a transcription error, or there wasn't an exact logging to what came in. We don't think it's going to turn out to be missing inventory.

The chance that these two positive specimens are somewhere outside of the laboratory is very small.

The way we have it stored, it can't be used in its current form as a weapon of mass destruction.
