A single-marker finger-prick test measuring 9am cortisol, commonly used to assess your body's stress hormone response, energy and sleep patterns.
1 biomarker as listed by Forth.
This test measures cortisol taken at 9am, the time of day cortisol is typically highest. Cortisol is your body's main stress hormone and is commonly used to assess how your body is responding to stress, along with its effects on energy, sleep and metabolism, though a single reading cannot diagnose a specific condition and ongoing symptoms are best discussed with a GP.
As a single-marker test, its depth score reflects that it measures exactly what it sets out to rather than being penalised for narrow scope. On price, £41 ties Forth with YorkTest's Stress (Cortisol) Test as the joint cheapest of the five tests in this comparison group, and sits below Medichecks' £45 and Better2Know's £55 and £195 equivalents.
value for money and collection convenience both score highly, the latter because the test can be done entirely at home. Clinical depth scores reasonably despite being a single marker, since the comparison group is built around single-marker cortisol tests. clarity and documentation and results and follow-up both score well because the biomarker, collection options and turnaround are published, and a doctor reviews the result.
This suits anyone who wants a quick check of their morning cortisol level, for example if they suspect ongoing stress is affecting their energy or sleep. Because it ties YorkTest's Stress (Cortisol) Test as the cheapest option in its group, there is little price advantage to be gained by switching, though those already using another provider's platform may prefer to stay with it.
You collect a finger-prick blood sample at home in the morning, or choose an AutoDraw device sample, a home nurse visit or a venous draw at a partner clinic. Results are returned within 2 days and reviewed by a doctor before you see your report.
