Hair Toxic Element Exposure Profile- Doctor's Data Test Kit

Hair Elements analysis provides information regarding recent and ongoing exposure to 31 potentially toxic metals.

Test Code: DDEX

Also Known As:


Specimen Type: Hair

Preparation: No fasting required. Collect the hair specimen according to the directions on the scale. Hair that has been permed, dyed, bleached, or otherwise chemically treated is vulnerable to contamination and is not recommended for analysis. Do not mix head hair with pubic hair.

Test Results: 5-7 Business days once the lab receives the specimen. May take longer based on weather, holiday or lab delays.


Hair Elements analysis provides information regarding recent and ongoing exposure to potentially toxic metals, especially methylmercury and arsenic, and time-averaged status of specific nutrient elements. This noninvasive screening test requires only .25 grams of hair.    

Test Includes:  Aluminum, Antimony, Arsenic, Barium, Beryllium, Bismuth, Cadmium, Cesium, Chromium, Cobalt, Copper, Gadolinium, Germanium, Gold, Lead, Manganese, Mercury, Nickel, Palladium, Platinum, Selenium, Silver, Tellurium, Thallium, Thorium, Tin, Titanium, Tungsten, Uranium, Vanadium, Zinc


This test is useful for

  • Toxic Element Exposure
  • Excessive Fish Consumption
  • Alopecia
  • Depression
  • Fatigue
  • Malabsorption
  • Hypertension
  • Impaired Glucose Tolerance
  • Kidney Function
  • Parkinson's-like Symptoms
  • Sexual Impotence or Decreased Testosterone Production
  • Vision Problems

Toxic elements may be 200 to 300 times more highly concentrated in hair than in blood or urine. Therefore, hair is the tissue of choice for detection of recent exposure to elements such as arsenic, aluminum, cadmium, lead, antimony and mercury. The CDC acknowledges the value of hair mercury levels as a maternal and infant marker for exposure to neurotoxic methylmercury from fish.

Hair, however, is vulnerable to external elemental contamination by means of certain shampoos, bleaches, dyes, and curing or straightening treatments. Therefore, the first step in the interpretation of a hair element report is to rule out sources of external contamination.

Hair element analysis is a valuable and inexpensive screen for physiological excess, deficiency or maldistribution of elements. It should not be considered a stand-alone diagnostic test for essential element function, and should be used in conjunction with patient symptoms and other laboratory tests.
