Is Hair Tissue Mineral Analysis Accurate?

Updated: Dec 21, 2020

I've been in the business of health, full time since 1976. I have learned a lot in that time and learning more and more by the day. I'm still trying to make sense of the Tsunami of confusion of health information that bombards us by the hour. One thing I have learned and am reminded about almost daily is the more I learn, the more I realise how little I know.


My partner, Alofa Kosena, and I are responsible for the New Zealand operation of Interclinical Laboratories. My primary job these days is to support and mentor NZ health professionals who use Interclinical's services. This essay is my opinion and does not represent the views of the company.

The following video from out of India is an easy to comprehend explanation of the HTMA we use. We send our hair samples to the same USA laboratory.

Being an expert in everything and a master of none

I realised about 15 years ago that I was at risk of knowing a lot about many things to do with health but failing to master anything. I needed to change. I needed to decide what I should be great at. What should I master? I liken this to a good all-round athlete choosing to specialise in one event as maturity nears.

The more I learn, the more I realise how little I know.

I decided 10 years ago to master the Hair Tissue Mineral Analysis Test (HTMA). I knew I could not do so for all the HTMA out there because that would mean I remain an expert only (there must be hundreds of different HTMA on offer!). That would be like an all-round athlete choosing to specialise as a cyclist, but still trying to be the best in every form of cycling. I chose just one HTMA test, the one I that I considered was the best of the lot - the Gold Standard of HTMA- the Interclinical Laboratories HTMA.


When an expert stands before an adoring audience and announces that hair tissue mineral analysis is not an accurate test and of no use for determining the nutritional status of a patient is he right? Probably not.

  • What training has he in the interpretation and application of HTMA?

  • Can he or
