Context
science4justice.nl is an open-access scientific archive founded by Dr Sarrita Adams. The site has published the most detailed public scientific analyses of the Letby medical evidence since 2023. This page summarises the archive’s principal contributions.
The insulin dossier
The site’s October 2023 piece “The insulin question” is still the canonical plain-English summary of why the Letby insulin evidence fails a forensic standard. It documents:
- The Roche Cobas immunoassay’s own manufacturer guidance requiring mass spectrometry confirmation for forensic use.
- Every known false-positive case in the assay’s published literature.
- The 2010 versus 2012 Royal Liverpool laboratory protocol change.
- The clinical conditions other than exogenous insulin that generate the assay pattern: auto-antibodies, sepsis, adrenal suppression, liver disease, kidney disease, drug cross-reactivity.
- The sample-handling failures: gel tubes, delayed centrifugation, ambient-temperature storage.
- The physiological implausibility of the reported 4,657 pmol/L value on the Crown’s own spiked-TPN theory.
The air-embolism dossier
The archive includes a line-by-line comparison of the Lee & Tanswell 1989 paper’s diagnostic criteria against the clinical descriptions used at trial. The comparison demonstrates that the trial descriptions do not meet the 1989 paper’s specificity criteria — which is the conclusion Dr Shoo Lee himself subsequently confirmed at the February 2025 press conference.
The scientific-method dimension
Beyond the case-specific analyses, science4justice.nl has published methodological pieces on how forensic use of clinical tests should work, what a differential-diagnosis framework requires, and why the methodology the Crown’s experts applied departs from modern clinical-science norms. This methodological framing has informed how the subsequent Panel report structured its own review.
Why the archive matters
At the time Dr Adams began publishing on the case, most UK press coverage was accepting the prosecution narrative. The archive was one of the few public-interest scientific resources where a reader could see the evidential critique worked out to primary-source detail. It filled the gap between specialist scepticism and public understanding for the crucial 2023–2024 window.
