They can interfere with iodine uptake, block thyroid hormone receptors, trigger autoimmune responses, and impair the conversion of T4 to the active hormone T3. Many people with thyroid symptoms have never had their toxic element levels assessed — this test fills that gap.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is urine used instead of blood for this test?\u003c\/strong\u003e\u003cbr\u003eDried urine is the most clinically appropriate sample for measuring urinary excretion of trace elements. The kidneys filter and excrete iodine, selenium, arsenic, mercury, and cadmium — making urine the most reliable indicator of ongoing exposure and body burden for these elements. Creatinine is measured alongside to correct for urine concentration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is ICP-MS and why does it matter?\u003c\/strong\u003e\u003cbr\u003eICP-MS (Inductively Coupled Plasma Mass Spectrometry) is the gold standard for trace element analysis. It detects elements at extremely low concentrations with high sensitivity and specificity — far beyond what standard laboratory methods can achieve. This level of precision is essential when measuring toxic elements that may be harmful even at trace levels.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan bromine really affect my thyroid?\u003c\/strong\u003e\u003cbr\u003eYes. Bromine is a halogen that competes directly with iodine for uptake into the thyroid gland. Even if your iodine intake is adequate, elevated bromine — from flame retardants, certain medications, or processed foods — can block iodine absorption and suppress thyroid hormone production. This is rarely tested on the NHS.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this test suitable for children?\u003c\/strong\u003e\u003cbr\u003eYes.

This test measures the most clinically relevant toxic metals in the appropriate sample type for each.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy are both blood and urine tested?\u003c\/strong\u003e\u003cbr\u003eDifferent elements are excreted and stored differently. Some toxic metals — like mercury and cadmium — are better measured in blood for recent exposure and in urine for longer-term or kidney-related accumulation.

Cadmium is a known oestrogen mimetic — it binds to oestrogen receptors and can drive oestrogen dominance, associated with PMS, endometriosis, fibroids, and breast cancer risk. Mercury disrupts thyroid hormone production and has been linked to irregular cycles, fertility problems, and worsening perimenopause symptoms.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is copper elevated in women on the pill?\u003c\/strong\u003e\u003cbr\u003eOestrogen — including synthetic oestrogen in hormonal contraceptives — increases copper retention. Women taking the combined pill or using a copper IUD often have elevated copper and a depleted zinc-to-copper ratio, associated with anxiety, low mood, oestrogen dominance, and thyroid dysfunction.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does magnesium deficiency affect women specifically?\u003c\/strong\u003e\u003cbr\u003eMagnesium is essential for progesterone production, oestrogen metabolism, and HPA stress axis regulation.
