Guardian Inquiry Spurs Change in AI Health Results
In a swift response to recent scrutiny, Google has removed its AI-generated overviews for several health-related queries following an investigation by the Guardian. The investigation uncovered that responses to queries, such as “what is the normal range for liver blood tests,” failed to account for important factors like nationality, sex, ethnicity, or age, potentially misleading users about their health status.
Selective Removal and Query Variations
According to updated findings, AI overviews have now been removed for the specific queries “what is the normal range for liver blood tests” and “what is the normal range for liver function tests.” However, related queries such as “LFT reference range” or “LFT test reference range” may still trigger AI-generated summaries. An early test conducted hours after the Guardian story confirmed that in several instances the overviews were absent, with Google even offering the option of an AI mode to handle the query. In some cases, the Guardian article documenting the change emerged as the top result.

Google’s Position and Internal Review
A Google spokesperson noted that the company does not publicly “comment on individual removals within Search” but emphasized its commitment to “making broad improvements.” An internal team of clinicians reviewed the contested queries and concluded that in many instances the information provided was accurate and supported by high-quality sources. Despite this, the selective removal highlights an ongoing challenge in balancing AI innovation with user safety in sensitive areas such as healthcare.
Industry Reactions and Broader Implications
Vanessa Hebditch, Director of Communications and Policy at the British Liver Trust, welcomed the removal as “excellent news.” However, she cautioned that focusing on a single search result misses a larger concern: the overall reliability of AI overviews in health contexts. This sentiment underscores the broader debate on the integration of AI in healthcare information delivery—a field where precision and accountability remain paramount.
Continued Evolution in Health Search Technology
Last year, Google introduced a suite of new features designed to enhance healthcare-related search outcomes, including refined overviews and dedicated health-focused AI models. While these steps signal a proactive approach, the incident highlights the persistent need for rigorous oversight as AI technologies evolve and intersect with critical health information.
