HTMA Test Canada: Hair Tissue Mineral Analysis

Hair Tissue Mineral Analysis (HTMA) measures mineral levels in your hair, which reflects what's stored in your body's tissues over the past 3 months. Blood tests show what's circulating right now—a snapshot that can change hour to hour. HTMA provides a longer-term view of mineral status and toxic metal accumulation that blood often misses, making it an excellent screening tool for identifying chronic imbalances.

Collection is simple and painless. You'll cut a small amount of hair (about 1 heaping teaspoon) from the nape of your neck, close to the scalp. This area is chosen because it grows most consistently. After ordering, you'll receive detailed instructions and your HTMA submission form by email to print at home. You'll need a plain paper envelope — available at any post office or office supply store — to mail your sample to our partner lab. The sample is virtually unnoticeable once cut.

For the most accurate results, it's best to test hair that hasn't been chemically treated. If you dye your hair, we recommend waiting until about 1 inch of new growth (approximately 4-6 weeks) before collecting your sample. Permanent treatments, bleaching, and perms can affect mineral readings. If you must test treated hair, let us know and we can note this on your analysis.

Results are typically delivered within a few weeks after the lab receives your sample. You'll receive an email notification when your report is ready, with a secure link to view and download your comprehensive analysis. Premium packages with consultation are prioritized and may be processed slightly faster.

We partner with CLIA-certified laboratories in the United States that specialize exclusively in hair tissue mineral analysis. These labs use ICP-Mass Spectrometry (the gold standard for trace element detection) and importantly, do not wash hair samples at the lab—a practice that has been shown to compromise accuracy of water-soluble mineral readings like sodium and potassium.

Yes. Hair analysis is recognized by the Environmental Protection Agency (EPA) as an effective method for monitoring heavy metal exposure. Research published in peer-reviewed journals supports its use for assessing long-term nutritional status. The International Atomic Energy Agency has also coordinated research programs using hair analysis for trace element assessment. Like any screening tool, HTMA is most valuable when interpreted by trained practitioners alongside clinical context.
