The National Institute for Health and Care Excellence has recommended a single saliva test that could help speed up the diagnosis of endometriosis in primary care, according to a BMJ report published on 16 September 2026. The decision adds a new option to the diagnostic pathway for a condition that can cause persistent pain and significant disruption to daily life.
The BMJ said the recommendation was made by NICE, which means the test may now be considered for use in primary care settings. The move is being presented as a step toward earlier identification of endometriosis, although the full impact will depend on how quickly services adopt it and how it is implemented in practice.
A new option for primary care diagnosis
Endometriosis is a common health issue that can be difficult to diagnose because symptoms are often non-specific and may overlap with other conditions. A faster test could help clinicians shorten the time between first presentation and referral, reducing uncertainty for patients who have been waiting for answers.
BMJ’s coverage places the development among the most recent health stories from 16 September 2026, alongside reports on asthma testing access and US measles deaths. That makes the NICE decision one of the more significant UK-focused health updates this week.
Why the recommendation matters
Earlier diagnosis matters because delays can affect treatment decisions, symptom management and quality of life. If a single saliva test is used effectively in routine care, it may reduce the need for more prolonged investigative pathways and help patients move sooner to appropriate specialist assessment.
For now, the BMJ report confirms the recommendation itself rather than detailed rollout timelines. That means the immediate story is the policy shift: a new diagnostic tool has been endorsed for primary care, potentially changing how suspected endometriosis is assessed across the NHS.
As with any new diagnostic approach, the real test will be adoption in clinics, clinician confidence and the extent to which it improves patient outcomes over time.
