A clinic-based blood test measuring cortisol, the hormone linked to your body's stress response, taken via a venous draw or home nurse visit. Suits people who want a clinician to take the sample rather than doing a finger-prick themselves.
1 biomarker as listed by Better2Know.
Cortisol is the hormone your adrenal glands release in response to stress, and this test measures its level from a blood sample taken by a clinician at a clinic or during a home nurse visit. Persistently high or low cortisol is commonly assessed alongside symptoms such as fatigue, weight changes, high blood pressure or muscle weakness, and alongside investigation for adrenal conditions. If you are experiencing ongoing stress-related symptoms, it is worth discussing them with your GP alongside any test result.
At £195 this is priced well above the rest of its comparison group: more than four times the £45.13 median across the five cortisol tests we track, and well above YorkTest and Forth's £41 home kits, Medichecks' £45 test and even Better2Know's own home finger-prick version of this same test at £55. Because it measures a single marker, our depth score reflects that testing breadth is not really the point of this comparison group.
It scores reasonably for collection convenience, since a home nurse visit is offered as an alternative to a clinic appointment, and well for clarity thanks to a clear description, reference-range guidance and stated turnaround. It scores poorly on value for money given how far above the group median it sits, and loses marks on results and follow-up because, as with Better2Know's other tests, results are not doctor-reviewed as standard.
This suits you if you specifically want a clinician to take your cortisol blood sample in person, or need a home nurse visit rather than a self-collected finger-prick. Testing is most meaningful when timed to the stated morning or midnight reference range.
For most people, Better2Know's own Cortisol Home Test Kit covers the identical single marker for £55, a saving of £140, and outside peers such as YorkTest and Forth charge around £41 for the same marker as a home kit.
A trained healthcare professional takes a blood sample at a Better2Know clinic, or you can arrange a home nurse visit instead. The sample is sent to the laboratory for analysis, and the fact sheet states results are ready within about 1 working day, viewable in your online patient account with notification by phone, SMS or email. It notes you can take results to your own GP or arrange a private doctor consultation through Better2Know; it does not state that results are doctor-reviewed as standard by default.
This clinic-based Cortisol Test costs £195, more than four times the £45.13 median for the five cortisol tests we track. Better2Know's own home finger-prick version of the same single marker costs £55, and outside peers such as YorkTest and Forth charge around £41. Results come back within about 1 day but are not doctor-reviewed as standard.
