We Compared Healf Bloods to a Standard Blood Test — Here’s What Won
How many times have you lain awake in bed late at night, wondering what’s actually behind your brain fog and tiredness, and told yourself you’d finally book a blood test to get to the bottom of it? Only to call the GP the next morning and find out that the earliest appointment is at least three weeks away. And so the question gets parked, and the cycle continues.
Your health is something you should never put on the back burner. So when we heard about Healf Bloods, a new at-home blood testing kit on the market, we decided to give it a try.
99.3% of people who’ve taken a Healf Bloods test came back with at least one biomarker outside the optimal range*, with most having no symptoms obvious enough to prompt a GP visit in the first place. That’s the gap this kind of testing is built for: catching what a “you seem fine” conversation might otherwise miss, before it becomes a bigger conversation.
Read on to find out how Healf Bloods compares to a standard blood test in terms of convenience, depth, and what you walk away with.

Healf Bloods Overview
The idea behind Healf Bloods isn’t to replace your GP; it’s to make it easier to check in on your own biology regularly, so you’re not waiting for something to feel wrong before you look into it.
The kit uses the Tasso device, a small, painless collection tool that takes under 1 mL of blood from your arm – no needle, no clinic. You post the sample the next day, and results land in your dashboard within 72 hours.
Depending on the kit, Healf Bloods tests 23 to 37 biomarkers, covering:
- Heart & cholesterol — Total, LDL and HDL cholesterol, ApoB, triglycerides
- Vitamins & minerals — Vitamin D, Active B12, Folate, Magnesium, Iron, Zinc
- Hormones — Testosterone, Oestradiol, Progesterone, Thyroid markers
- Liver & kidney function, inflammation, and more
What sets it apart from a standard blood report:
- Simple explanations for every biomarker; what it is, and why it’s on the panel
- Personalised, scored recommendations based on your results, not generic ranges
- Discounted 1:1 consultations with an in-house nutritionist to talk through your results
- A dashboard that tracks your biomarkers over time, so you can see what’s changing
The kit starts from £79, with a membership option (two tests a year, plus a complimentary consultation after each one) for anyone who wants to track how their biology shifts across the year rather than just a once-off thing.
The Standard Blood Test Overview
A standard blood test (through your GP, a private clinic, or a walk-in lab) is the version most of us grew up with, and it’s backed by decades of clinical use for good reason.
What it usually asks of you is more time and more blood. Clinics typically draw upwards of 10 mL via a needle, which for some people is the main reason they put testing off in the first place. And then there’s the logistics: booking an appointment, taking time out of your day to get there, sitting in a waiting room, and often waiting weeks just to get a slot.
The results themselves often arrive as a raw lab report, sometimes weeks later, leaving you to work out what they actually mean – and often needing to consult your GP to interpret the results.
Final Verdict
If what’s stopping you from checking in on your health is the needle, the booking hassle, or getting a report back that you can’t make head or toe of, Healf Bloods is built to remove all three of those barriers.
The reason we’d back Healf Bloods over a one-off standard test is what happens once people start testing regularly:
- Members sleeping 6+ hours a night showed 21.6% higher testosterone and 37.1% higher progesterone than those sleeping less.*
- Members who’d taken antibiotics in the past year showed 38.9% higher CRP (a marker of inflammation) than those who hadn’t.*
- Daily exercisers had 15.2% lower ApoB and 12.2% lower LDL cholesterol than people training less than twice a week.*
- Daily coffee drinkers showed 6.3% lower copper and 4.0% lower zinc, a sign of hindered mineral uptake.*
It doesn’t replace the role your GP plays, especially for anything that needs a proper diagnosis or treatment. But as a way to keep a regular, understandable eye on your own biomarkers, and get direction on what to do with that information, Healf Bloods is an excellent starting point.
