About this test

This test collects four saliva samples over the course of a day to trace how your cortisol levels rise and fall. Cortisol naturally peaks in the morning and tapers off as the day goes on, so a single blood test only catches one point on that curve. Testing four times is used to assess whether that daily rhythm looks normal, or whether cortisol is running persistently high or low, patterns linked to conditions such as Addison's disease and Cushing's disease. The provider notes that the night-time reading is often the most informative of the four.

There's no comparison group of similar cortisol-rhythm tests in our catalogue yet, so we can't say how the £94.25 price or the four-sample format stacks up against alternatives elsewhere.

The test scores well for clinical depth, since four biomarkers puts it among the higher end of hormone tests we track, and for collection convenience, as it's done entirely at home with results back in around two days. It also scores well for results and follow-up because a doctor reviews the results. It's marked down slightly on clarity and documentation: the listing sets out the sample type, collection method and turnaround, but doesn't describe what the final report will look like. Blue Horizon Medicals works with UKAS ISO 15189 partner labs and has been trading since 2009.

Who is it for?

This suits you if you want to track your cortisol pattern across a full day rather than relying on one snapshot reading, for example when investigating fatigue, disrupted sleep or a possible imbalance in adrenal hormone output. It's a reasonable next step if a single cortisol test hasn't given a clear picture. We don't have a directly comparable four-point saliva cortisol test in our catalogue, so we can't say whether it's the cheapest or most detailed option for this specific test type. If you have persistent symptoms, see your GP alongside using this test.

How it works

You collect four saliva samples yourself at home at set points across the day and post them to the lab. The fact sheet doesn't detail the lab process beyond this. Results are typically back within 2 days, and a doctor reviews them before they reach you.

Pros & cons

Pros

  • Four samples across the day capture your cortisol rhythm, not just one snapshot.
  • Fully at-home saliva collection, no clinic visit needed.
  • A doctor reviews your results before they're sent to you.
  • Turnaround of around 2 days.

Cons

  • The provider doesn't describe what the final report looks like.
  • No comparable four-point saliva cortisol test in our catalogue to check the £94.25 price against.

Our editorial score

Compare Health Test Score Four-point saliva cortisol test with a 2-day turnaround
Editorial confidence: 10.0/10

This test measures cortisol across four points in the day, rather than a single blood draw, so it can show whether levels are following their normal daily rhythm. At £94.25 it has no directly comparable test in our catalogue yet, so we can't say how its price stacks up against peers. The main trade-off is that the provider doesn't say what the final report looks like.

Score breakdown

  • Clarity and documentation 7.0/10

    4 biomarkers, placing it in the 95th percentile of hormones tests we track.

  • Collection convenience 7.0/10

    A saliva sample you take at home, no needle; results in around 2 days, slower than similar tests.

  • Results and follow-up 7.0/10
