The Science Behind Dog Hair Analysis

Hair tissue mineral analysis is considered a standard test used around the world for the biological monitoring of trace elements and toxic metals in humans and animals. Hair, like all other body tissues, contains minerals that are deposited as the hair grows.

Several factors combine to make Dog Hair Analysis® the best mineral test in the industry! Key to the success of the DHA program is the laboratory, which uses only the most advanced and sophisticated instrumentation available today. The hair samples are tested with the Perkin Elmer Elan 9000 ICP Mass Spectrometer to assess mineral levels in milligram percent (mg%).

This demonstrates the number of milligrams of the mineral/metal present in 100 milliliters of solution. The result is an extremely accurate reading of your pets’ biochemistry during the last 90 days.

The hair is not washed (chemically rinsed) at the lab. Studies have proven that laboratories who do not wash the hair showed superb reliability. Washing hair samples has been revealed to erratically leach the water-soluble elements, which creates much less accurate results.

The laboratory has stringent quality control procedures, including controls which are tested at the beginning, middle and end of every batch of hair samples to ensure the accuracy of the results. Also, any reading that is out of a normally expected range is retested before laboratory results are sent out.

Dog Hair Analysis® is more accurate than blood testing

Traditionally mineral levels have always been evaluated via blood tests. Using blood testing to evaluate mineral levels often leads to inaccurate results due to the dog’s variable food and water intake throughout the day. The level of mineral present in the blood stream is greatly dependent on what time of the day the blood is drawn, compared to what time you feed your pet his/her meal(s) and supplements. Blood work is considered an immediate snapshot at that precise moment.

Also, a particular mineral may be found in the blood stream at the time of testing, but it may not go to the target tissue, to be up taken and utilized as it is provided in a bio-unavailable form. It may simply be in the blood stream awaiting excretion via the liver or kidneys.

Dog Hair Analysis® testing, on the other hand, evaluates the last 90 day average of the vitamins and minerals that actually made it into the tissues. When vitamins, minerals and metals are found in the hair it means that these nutrients were not only digested, absorbed, metabolized and utilized, but they also made it through to the hair. This provides you with an extremely accurate reading of your dogs’ biochemistry.
