Who is this test for?

Nutritional imbalances — in vitamins, iron, minerals and thyroid hormones — can quietly affect any child's mood, energy, focus and sleep. A simple blood screen helps rule these out early.

General wellness check

"I just want to make sure my child is getting everything they need." Vitamin D, iron and B12 deficiencies are far more common in children than most parents realise — and easy to miss without testing.

Focus, sleep or behaviour concerns

Before exploring anything else, it's worth ruling out whether a nutritional or thyroid imbalance is a contributing factor. This screen covers the most common culprits — quickly and gently.

Children with ADHD

Low iron, vitamin D, magnesium and zinc are known to affect attention and energy in any child — and are worth checking and optimising alongside any existing ADHD management. This test does not diagnose ADHD.

Autism, Tourette Syndrome & other neurodivergent conditions

Many parents find it useful to screen for nutritional factors that may be affecting their child's mood or sleep, separately from their diagnosis. This is a wellness screen only — it does not test for or diagnose any neurodevelopmental condition.

Needle-nervous children of any kind

The Tasso device has no visible needle at any point. Most children barely notice it. Done at home, in a familiar space, it's a completely different experience from a clinic blood draw — for any child who finds that difficult.

Already on supplements or medication?

If your child has recently started vitamins, dietary changes, or new medication, a baseline screen — and a follow-up a few months later — shows what's actually working. Our annual plans are designed exactly for this.

Gentle by design

A different kind of blood test

The Tasso device was designed from the ground up to make blood collection comfortable — for any child, and especially for those who find needles, clinics, or new experiences difficult.

No visible needle
The micro-lancet retracts in under a second — there is nothing to see at any point.
Familiar surroundings at home
No waiting room, no clinical smell, no strangers. Your child chooses where they sit.
Around 6 minutes
The whole collection process is brief — with no holding still for extended periods.
Child can be in control
Your child can press the button themselves. Feeling in control makes a real difference for many children.
Important: This is a nutritional and metabolic wellness screening panel. It does not diagnose, detect, or test for ADHD, autism, Tourette Syndrome, or any neurodevelopmental condition. It is a sensible complement to — never a replacement for — any existing diagnosis, therapy or care.

Track progress over time

Annual plans — two tests, one year

Many parents like to test again a few months after starting supplements, dietary changes, medication or new routines — to see what's actually changed. Annual plans include two tests, six months apart, with the cost spread evenly across 12 monthly payments.

Payments are spread over 12 months even though your two tests are 6 months apart — nothing extra to pay later.

After the test

Results & what happens next

Results in 5–7 working days. A clinician reviews every report before it reaches you.

Sample received by lab

Your sample arrives at Alderley Lighthouse Labs (UKAS-accredited) and is processed within 2–3 working days.

Clinician review

A clinician reviews your child's results before they're released. If anything needs prompt attention, we will contact you directly.

Plain-English report

You receive a clear, jargon-free report explaining what each result means — with specific recommendations where results are outside the optimal range.

Follow-up if needed

A follow-up consultation with a Lambert GP is available to go through the results together — recommended if any markers require action.

Important: this is a wellness screening tool, not a diagnostic test

This panel screens for common nutritional imbalances that affect any child's mood, energy, focus and sleep. It does not diagnose ADHD, autism, Tourette Syndrome, or any other condition. Results should be considered alongside — and never instead of — your child's existing diagnosis, therapy, or clinical care. If you have specific concerns about your child's development, please speak to your GP or specialist.

Frequently asked questions

The Tasso device uses a spring-loaded micro-lancet that retracts in under a second — there is no visible needle at any point. Most children describe it as a gentle tap, or nothing at all. The device sits against the upper arm for around 6 minutes while a few drops are collected automatically. Many children are surprised at how easy it was.

Just a few drops — a tiny fraction of what a standard blood draw collects. There are no syringes, no blood bags, and no veins involved. The Tasso device collects a small capillary sample from the skin surface, enough to run a comprehensive panel of up to 42 biomarkers.

Yes — the at-home kit is designed specifically for parents. Full step-by-step instructions are included, along with a short how-it-works video and a prepaid Royal Mail return envelope. The whole process takes under 10 minutes from start to posting. An additional £12 covers delivery of the kit to your address.

Yes — this is one of the main reasons we chose the Tasso device. There is no visible needle at any point. Done at home, your child is in a familiar, comfortable environment — which makes the whole experience significantly calmer for children who find clinics or waiting rooms overwhelming. Your child can be involved at their own pace, including pressing the button themselves if they'd like to.

Results are typically ready within 5–7 working days of the lab receiving your sample. You'll be notified as soon as your report is available. If any result requires prompt attention, a clinician will contact you directly.

No — and it is important to be clear about this. This is a nutritional and metabolic wellness screening panel, not a diagnostic test for any neurodevelopmental condition. It does not diagnose, detect, or screen for ADHD, autism, Tourette Syndrome, or any other condition.

What it does is check for common nutritional imbalances — in vitamins, minerals, iron and thyroid function — that are known to affect mood, energy, focus and sleep in any child. Identifying and addressing these imbalances is a sensible step alongside (never instead of) your child's existing diagnosis, therapy or care.

The test is suitable for children of most ages. We recommend it from around age 4 upwards, though we're happy to advise for younger children — please contact us if you're unsure. There is no upper age limit; the panel is equally useful for teenagers.

The at-home kit includes the Tasso sampling device, full step-by-step instructions, and a prepaid Royal Mail return envelope for sending the sample back to the lab. An additional £12 covers delivery of the kit to your address. In-clinic appointments carry no extra charge — the sample is taken on-site at no additional cost.

Annual plans are designed for parents who want to track changes over time — they include two tests, six months apart. If you only want a single one-off test, our single test packages (Basic £149, Enhanced £165) are the better fit and carry no ongoing commitment.

Yes — the Fatty Acids add-on (£80) can be added at the time of either or both tests within an annual plan. It is charged separately as a one-off at the point of each test, and is not included in the monthly plan price. Simply let us know when booking your test.
