Each ratio is calculated from the mineral levels and interpreted against established Trace Elements Laboratory reference values. The ratios reveal patterns that individual mineral values alone cannot identify.
People who cannot or prefer not to do blood draws
Hair collection requires scissors and thirty seconds. For anyone with needle phobia, difficult veins, or simply a preference for non-invasive testing, HTMA provides a meaningful clinical picture without venepuncture.
Children
Assessing mineral status, toxic metal exposure, and metabolic patterns in children without blood draws. Particularly relevant for children with fatigue, behavioural concerns, learning difficulties, or frequent illness.
A lower-cost first investigation
For those who want functional testing but are not ready for the full five-test TDG programme. HTMA generates clinical hypotheses that indicate which follow-up testing is most likely to be highest yield — often pointing clearly toward blood chemistry, DUTCH, or OAT.
Heavy metal burden investigation
When heavy metal exposure is suspected from occupation, old property, diet, or amalgam fillings, HTMA provides an initial excretion pattern assessment without the cost of provoked urine testing. Elevated toxic metals on HTMA inform whether the full investigation is warranted.
Adding a mineral dimension to blood chemistry
Blood chemistry and HTMA read mineral status from different perspectives. Blood measures current serum concentration. HTMA measures the excretion pattern over 8–12 weeks. Together they provide a more complete picture than either alone.
People who struggle with stool or timed urine collections
The GI-MAP and DUTCH have collection protocols that some people find challenging — timed samples, specific timing requirements, sensitivity around stool collection. HTMA has no timing requirements and no special collection conditions.

HTMA fills gaps that blood, stool, and urine tests leave. Each cross-reference below shows where HTMA adds a clinical dimension the other test cannot provide alone.
vs Blood Chemistry
Blood measures current serum minerals. HTMA measures the 8–12 week excretion pattern. Low serum magnesium tells you there is deficiency now. Low HTMA magnesium with high HTMA calcium explains why the Ca/Mg ratio has been disrupting blood sugar and sleep for months.
vs DUTCH Plus
The DUTCH shows the cortisol pattern. HTMA shows what that cortisol pattern has been doing to your mineral status over months — the Na/Mg adrenal ratio and Ca/Mg blood sugar ratio reflect the hormonal environment, not just the hormones themselves.
vs OAT
Elevated OAT pyroglutamate indicates glutathione depletion from oxidative stress. Elevated HTMA toxic metals identify whether heavy metal accumulation is the source of that oxidative demand — connecting the downstream signal to the upstream cause.
vs GI-MAP
Low HTMA cobalt indicates low stomach acid — the same upstream factor that allows gut dysbiosis to establish. HTMA and GI-MAP together connect the mineral basis of digestive insufficiency with the gut ecology consequences that follow from it.
