Discovering the Power of Hair Tissue Mineral Analysis (HTMA) for Your Child's Health
Updated: Sep 9
If you've been searching for answers about your child's health — their energy, mood, behaviour, and gut — you may feel like you've hit many dead ends. Tests often come back "normal," and practitioners might mean well but still miss the mark. You might sense that something is being overlooked.
Hair Tissue Mineral Analysis (HTMA) is one of the most underused tools in paediatric functional nutrition, and it's usually where I start. In this article, I’ll explain what HTMA is, how it works, and why it can be so revealing for children with neurodevelopmental and neuroimmune conditions.
What is Hair Tissue Mineral Analysis (HTMA)?
HTMA is a non-invasive laboratory test. It analyses a small sample of hair, usually taken from the back of the head, close to the scalp. This test measures the levels of minerals and heavy metals stored in the body's tissues.
Unlike a standard blood test, which gives you a snapshot of what's circulating in the bloodstream at a single moment, HTMA reflects what's been happening over a longer period — typically the past three months. This makes it particularly useful for identifying patterns and trends rather than just acute fluctuations.
The test measures a wide range of nutrients and minerals, including:
Essential minerals — calcium, magnesium, potassium, sodium, zinc, iron, copper, manganese, and more
Trace elements — selenium, chromium, molybdenum, lithium, boron, and others
Heavy metals — lead, mercury, cadmium, arsenic, aluminium, and nickel
Why Is HTMA Useful for Children with Neurodevelopmental Conditions?
Children facing challenges such as autism, ADHD, PANS/PANDAS, anxiety, tics, or complex gut-immune issues often run on depleted reserves. Their systems are under significant demand, and standard tests frequently miss the subtle imbalances that can drive their symptoms.
Mineral imbalances and heavy metal burdens can contribute to a wide range of issues, including:
Poor sleep and low energy — Magnesium, zinc, and calcium all play roles in sleep regulation and nervous system function.
Mood dysregulation and anxiety — A copper-zinc imbalance, in particular, is associated with heightened anxiety and sensory sensitivity.
Digestive issues — Mineral status influences gut motility, enzyme function, and the gut-immune axis.
Immune dysregulation — Minerals like zinc and selenium are critical for immune regulation and the body's ability to manage inflammation.
Cognitive function and focus — Iron, zinc, and iodine all support brain function and concentration.
Detoxification — The body's ability to clear heavy metals and other toxins is directly dependent on mineral status.
For children with PANS or PANDAS, the body's ability to mount and resolve an immune response is closely tied to nutritional status. HTMA can reveal whether the terrain is making a child more vulnerable to flares — and what steps can be taken to address it.
What Does the Process Look Like?
One of the things parents appreciate most about HTMA is how simple the collection process is. There are no needles or clinic appointments. You collect a small hair sample at home using the kit provided by the lab and send it directly to them.
Order the test kit directly from the lab (currently £71.10, paid to the lab).
Collect a small hair sample at home — the instructions are clear and straightforward.
Post the sample to the laboratory for analysis.
Your results are reviewed thoroughly before the consultation, alongside your pre-consultation health questionnaire.
Meet online — by phone or Microsoft Teams — to go through the findings together.
Receive a personalised nutrition and supplement plan designed to address what the results show, written to be simple and realistic for family life.
What Can HTMA Tell Us That a Standard Blood Test Won't?
Standard blood tests measure serum levels — what's floating around in the blood at a given moment. However, many nutrients are tightly regulated in the blood. The body will pull from tissues and bones to keep serum levels stable, even when tissue stores are depleted. This means blood tests can appear normal even when there's a significant deficit at the cellular level.
That said, HTMA isn't a replacement for other investigations. It's one piece of the puzzle, used alongside a thorough health history and, where appropriate, other functional tests such as OAT or GI-MAP stool testing.
Who Is HTMA For?
HTMA is beneficial for children facing a variety of challenges, including:
Autism spectrum conditions
PANS/PANDAS
ADHD and attention difficulties
Anxiety and emotional dysregulation
Tics
Complex gut and immune challenges
ARFID
Unexplained fatigue or recurrent illness
HTMA is also available as part of parent-only support packages — because the toll of caregiving is real.
A Note on What HTMA Is Not
HTMA is a functional nutrition tool, not a diagnostic test. It does not diagnose medical conditions and is always complementary to — never a replacement for — your child's paediatrician.
Understanding the Importance of Nutritional Status
Nutritional status is crucial for overall health, especially for children with neurodevelopmental challenges. Many parents may not realise how much nutrition impacts their child's behaviour, mood, and overall well-being.
When we focus on providing balanced nutrition, we can help support our children's systems. This can lead to improvements in energy levels, mood stability, and even digestive health.
The Role of Essential Minerals
Essential minerals play a significant role in our children's health. For instance, magnesium is vital for muscle function and energy production, while zinc supports immune function. Ensuring your child has adequate levels of these minerals can make a world of difference.
The Impact of Heavy Metals
Heavy metals can be detrimental to health, particularly for children with neurodevelopmental issues. They can interfere with normal brain function and exacerbate symptoms. HTMA can help identify heavy metal burdens, allowing for targeted interventions.
