Lucy Letby BBC Panorama Refuting Misleading Insulin Claims

The host provides a detailed scientific rebuttal of the insulin claims made in the BBC Panorama documentary and in the accompanying book by Judith Moritz and Jonathan Coffey. He demonstrates that the Roche Cobas immunoassay used in the case is a screening test — its own manufacturer's labelling states it is not suitable for investigating factitious hypoglycaemia — and that the United Kingdom and Ireland Association of Forensic Toxicologists explicitly requires confirmatory mass spectrometry before any immunoassay result is used in a legal setting. Neither test was carried out. He explains that thirty to sixty percent of neonates experience hypoglycaemia naturally, that the yo-yo glucose pattern attributed to poisoning is consistent with standard bolus treatment errors, and that the third insulin case — an infant with documented congenital hyperinsulinism — was never shown to the jury. He is particularly critical of Judith Moritz for failing to seek comment from any expert sceptical of the prosecution, identifying no sources, and misrepresenting what the international expert panel actually said.
