In clinical trials, the cargo is the data. A sample compromised in transit is a data point lost forever — and possibly a subject visit that has to be repeated, an enrollment number that has to be increased, a timeline that slips. The trial sponsor's FDA submission depends on cold-chain and chain-of-custody integrity end to end.
