The "Counting Rules" for Evaluating Hair Tests

Updated: Jun 15, 2023


In his second book, Hair Test Interpretation, Andy Cutler talks about how the medical community only understands occupational poisonings and is completely unaware that most poisonings now occur at home. The medical community also does not understand how to test or interpret tests for mercury. Blood and urine are often normal in very toxic people and hair tests are hard to interpret.


By looking at hundreds of hair tests Andy developed 5 statistical rules to check for signs of mercury toxicity. “This book," he says about Hair Test Interpretation "is the result of finding all the relevant information wherever it was and verifying it was accurate by cross checking it against real hair tests as well as the situations of real people I am familiar with through case consulting, internet discussion groups or other means. “


A hair test must be interpreted with care. Very frequently, a highly toxic person will have low mercury in their hair, but the essential elements section of the test will show an abnormal pattern. This is because mercury messes with the mineral transport proteins that move essential elements across cell walls. A strand of hair is made up of dead cells pushed out and stacked up to form the strand.


Andy was a chemical engineer and used concepts from engineering to come up with the five statistical tests we use to evaluate hair tests. An important engineering concept is statistical process control. At manufacturing facilities, process engineers have rules and tests for products to check for problems that might require a manufacturing line to be shut down to be recalibrated. "Mercury,” he tells us, “interferes with the process by which our body moves minerals around and regulates their concentration.” When this is happening, a hair test will show “out of control” results. Out of control results point to what he called “deranged mineral transport,” which only mercury cause to a significant extent. And out of control results will correspond to the out-of-control health histories we see so commonly in mercury toxic individuals.


Andy developed these five statistical tests he called “the counting rules,” with a friend who was a statistician. They apply the same criteria used in process control charts for checking for how many points are outside two sigmas (in the red) how many are outside one sigma (not in the middle band) and how many are on one side of the mean.


He explains the tables and charts and formulas he and his statistician buddy used to develop the “counting rules” in an appendix to Hair Test Interpretation. “This a bit brain numbing for those who aren’t scientific or engineering techno-geeks who love caressing every button on their calculator.” I will leave that section to the techno-geeks to pore over and enjoy. I am absolutely not one of you!


If you fear you have too many heavy metals in your system don’t listen to your doctor or your naturopath as they will order the wrong tests. These tests will not be diagnostic and you can actually harm yourself taking a provoked urine test, which all the naturopaths want to do to you. What you want is a toxic and essential elements hair test. We like Doctor’s Data lab. You need a doctor to order this or there is a link on my website where you can order it yourself using a company called Direct Labs. When you have your results you can buy The Detox Manual, or Hair Test Interpretation and interpret them yourself, or you can join our Andy Cutler chelation Facebook group and get them looked at for free.


Please like and share and so forth. I am starting to get a bit freaked out by all the comments I read on Substack and Twitter from moms of injured children. This method I write and talk about is the best thing we’ve got right now for getting kids better. It is an urgent situation and more people need to know about the Andy Cutler protocol.


The hairtest we use to evaluate for mercury toxicity is Doctor's Data: "Toxic and Essential Elements Hairtest." You can order it here from Direct Labs.
