Rare disease patients in England may be waiting longer for answers because NHS laboratories are not consistently sharing data that can speed diagnosis and improve care, according to a BMJ report published on October 8, 2026. The findings add fresh pressure on a system already under strain, with clinicians and researchers warning that fragmented information is making it harder to identify inherited and complex conditions early enough for treatment and support.

Data gaps are slowing a process that depends on collaboration
The BMJ said the problem is especially significant for rare diseases, where diagnosis often relies on combining results from different laboratories, specialist services, and genomic teams. When that information is not shared efficiently, patients can face delays in diagnosis, repeat testing, and uncertainty about next steps in care. The report also pointed to broader system reforms and data-sharing efforts as part of the solution, including the role of NHS data infrastructure in supporting research and service improvement.

Why rare disease care is particularly exposed
Rare diseases are difficult to diagnose precisely because each individual condition affects relatively few people and may present with non-specific symptoms. The BMJ report argued that timely access to laboratory information is essential in these cases, not only to confirm a diagnosis but also to guide treatment, family counselling, and access to specialist services. Without that joined-up approach, patients can remain in diagnostic limbo for months or even years.
What the latest findings mean for the NHS
The report comes at a time when the NHS is under pressure to improve speed, consistency, and coordination across services. For rare disease patients, better data sharing could help reduce avoidable delays and make it easier for clinicians to recognise patterns that point to a diagnosis. The BMJ’s findings suggest that laboratory systems, not just frontline appointments, can shape how quickly patients receive answers.
The message from the report is clear: rare disease care depends on information moving as fast as the clinicians who need it. If that flow remains fragmented, patients may continue to pay the price in missed opportunities for earlier diagnosis and more effective support.
