- Data for sample hv46bd2 and f7qjrbk were swapped following a clerical error by Finnrick. On 6 May, the error was corrected.

- Test results for sample pst3r4y were published from 31 Oct to 17 Nov 2025, but did not belong to Peptide Sciences: the sample was misidentified, and re-attributed to the correct vendor.
