Signature combines a venous blood draw with an additional sample to cover 443 biomarkers, spanning areas such as heart health, cholesterol, diabetes and blood sugar, full blood count, kidney and liver function, thyroid function and antibodies, hormones, autoimmune markers, Epstein-Barr virus markers, gut bacterial composition, and vitamin D. The provider states it combines blood and urine testing with gut microbiome, food sensitivity, and nutritional and lifestyle DNA analysis, and includes a private GP consultation afterwards to go through the results and plan next steps.
Against its comparison group, Signature is priced far above every peer: the group median is £407.50, and even the next most expensive option, Stride's 180-marker Vital Duo at £460.85, costs a fraction of Signature's £2,112. In return, Signature tests roughly 2.5 times as many markers as Vital Duo. Within Randox's own range, Signature also differs from RanChip Insight 360 (£495, 160 markers) chiefly by including a doctor consultation, which RanChip does not.
The scores show this trade-off clearly. Clinical depth is the maximum score, since 443 biomarkers is far above the 82.5 median for the group. Value for money is low given the price gap versus peers. Results and follow-up scores reasonably well because a doctor consultation is included. Collection convenience is limited by the clinic visit, additional sample and multi-day wait, even though results come back within 4 working days.
Who is it for?
This suits people who want the deepest panel Randox offers and are prepared to pay a substantial premium for it, along with a private GP consultation to discuss the results. For most people wanting a broad health check, cheaper options in the same comparison group cover 50 to 180 markers for a fraction of the price, and Randox's own RanChip Insight 360 covers 160 markers for £495 without the GP consultation.
How it works
You attend a Randox Health clinic for a venous blood draw plus an additional sample covering the gut microbiome, food sensitivity and DNA components. Results are available within 4 working days, after which you have a private GP consultation to go through them.
