Same-day metagenomic test finds hidden infections in critically ill children at Great Ormond Street
A study in Lancet Microbe of 122 critically ill children at Great Ormond Street Hospital found that same-day metagenomic testing detected infections that routine tests missed and changed antibiotic prescribing in a quarter of cases. The service is being rolled out to about 30 UK intensive care units.

Mixed · 2Researchers at Great Ormond Street Hospital (GOSH) in London used a same-day metagenomic test on respiratory samples from 122 critically ill children in the paediatric intensive care unit during 2024-25.

Centre · 1The BBC said the usual method of identifying bacteria is culturing them in Petri dishes, a technique used since Victorian times, while PCR can identify viruses and some bacteria but needs doctors to specify targets. BBC NewsN “the most common method of identifying bacteria is by trying to culture them in Petri dishes, a technology that has been used since Victorian times.” Read at BBC News ↗ Mixed · 2The test identified around nine in 10 bacteria and viruses and all fungi in the samples, and detected 50 organisms that routine diagnostics did not identify.

Mixed · 2Dr Sam Ray, a GOSH consultant in paediatric intensive care and study co-author, said the study helped staff spot missed infections, get children onto the right treatment and stop antibiotics that would not work, which he said matters for tackling antimicrobial resistance. BBC NewsN “The study has helped us to spot infections we would have missed, get children on the right treatment and stop antibiotics when we know they aren't going to work.” Read at BBC News ↗ GB NewsR “Removing unnecessary treatment is incredibly important for the fight against growing antimicrobial resistance,” Read at GB News ↗ Mixed · 2Ten-year-old Willow Crowther, from Kent, became gravely ill with pneumonia in March, with a seizure and multiple cardiac arrests, and her mother Stacey Moore said the family was told to come and say goodbye; the BBC said she was given a 50% chance of survival.

Mixed · 2Dr Julianne Brown, head of the GOSH Metagenomics Service and co-senior author, said the testing is being gradually rolled out to around 30 intensive care units across the UK, and could quickly detect a new pandemic-threat pathogen.

- Framing
- BBC health reporting led by a patient story and explained the science, with context on older testing methods and the research lineage.
- Emphasis
- Willow's case, comparison with culture and PCR, publication in Lancet Microbe, adult trials at Guy's and St Thomas'.
- Leaves out or plays down
- Does not give much on limitations of the test beyond detection rates.
- Charged language
- “pioneering”
- For example
-
“A pioneering same-day test has been used to detect hidden and drug-resistant infections among children in intensive care.” — BBC News
Right1 outlet
- Framing
- GB News presented the findings as a medical breakthrough, leading with the test and study results and using Willow's case as illustration.
- Emphasis
- Study numbers, the test's precision and the role of doctors' quotes; pandemic-readiness and national rollout.
- Leaves out or plays down
- Omits the Lancet Microbe publication, the 50% survival estimate, Willow's months-long recovery, and the comparison with culture and PCR methods.

- “Groundbreaking”“uncovered”“entirely missed”
- For example
-
“A groundbreaking same-day diagnostic test that sequences all genetic material in a patient sample has helped uncover hidden and drug-resistant infections in seriously unwell children.” — GB News
What every side reports
- The study covered 122 critically ill children in GOSH's paediatric intensive care unit in 2024-25.

Metagenomics topic
Presented by GOSH clinicians as a tool that identifies infections standard tests miss, guides antibiotic use and could give early warning of new pathogens.
“Metagenomics can detect infections that standard tests miss, meaning better outcomes for some critically ill patients.” — BBC News
