About this test

This test measures more than 70 biomarkers linked to cardiovascular health, hormone balance, nutrient status, kidney and liver function, and blood cell counts, including cholesterol markers, HbA1c, hsCRP, vitamin D, ferritin and thyroid markers such as TSH and FT4. These are commonly used to build a broad picture of current health status. The sample is collected via an at-home venous blood draw carried out by a visiting phlebotomist.

Against the wider group of general health checks with over 50 markers, its 70 biomarkers sit a little below the group median of 82.5, and its £399 price is almost exactly in line with the £407.50 group median, about 2% below it. Compared with individual peers, it covers more markers than Medichecks' Optimal Health Blood Test (59 markers, £249) and Blue Horizon's Comprehensive Gold panels (54 and 52 markers), but fewer than Randox Health's Everyman and Everywoman Complete (95 markers each, £416) or its own RanChip Insight 360 (160 markers, £495).

It scores well for clarity and documentation, since Stride publishes the full biomarker list, sample type and turnaround. Clinical depth and value for money both score around the middle, reflecting a marker count and price close to the group average. It scores lower for results and follow-up: a consultation is included, but results are not reviewed by a doctor and Stride does not describe the report format.

Who is it for?

This suits people who want a broad, general blood-based health check without the hassle of a clinic visit, and who are comfortable with a price close to the middle of the market for this kind of panel. It sits between cheaper, narrower panels and the deepest, most expensive options.

If a lower price matters more than marker count, Medichecks' Optimal Health Blood Test covers 59 markers for £249. If you want more markers at a similar or higher price, Randox Health's Everyman/Everywoman Complete cover 95 markers for £416, or its RanChip Insight 360 covers 160 markers for £495.

How it works

A phlebotomist visits you at home to take a venous blood sample, so there is no need to attend a clinic. Stride states results are returned in around 7 working days. A one-to-one consultation is included in the price, though results are not reviewed by a doctor, and Stride does not describe what the results report looks like.
