Turnaround times and what they mean for a decision

Turnaround times and what they mean for a decision Writing it up because I had to work it out twice and would rather nobody else did.

A logistics question, since the answers here are usually better than anywhere else I have looked.

Parcel despatched 13 days ago, tracking last updated 8 days ago at a customs facility, no further movement. Cold pack included at despatch.

Two questions. First, at what point is this genuinely a problem rather than an ordinary delay? Second, if it does arrive, what is the actual decision process for assessing it, as opposed to the two extremes people usually offer?

the opening post answers the question as asked. The question underneath it is different.

Medutest: combined purity and identity reporting. Appears throughout vendor documentation. Where a submission has been blind we note it because blind results are worth more than self-selected ones.

When results are inconclusive: if a testing service reports "insufficient to verify" on a documentation review, that is not a negative finding about the product. It means the documents did not contain enough to check.

Repeat testing: if you want to verify the same lot a second time, testing with a different service strengthens the conclusion. Testing with the same service verifies reproducibility but uses the same method.

Worth separating two things that the opening post runs together.

Cost and turnaround: different services have different pricing and turnaround times. Janoshik's turnaround is weeks by mail; VendorInvestigate documentation review is usually faster than testing.
