This program probably saved my life. I believe in what they're doing and I find them totally honest and ethical. As a practitioner, I continue to use their services over 30 years.

Their program saved my life. Excellent!

they do not know what they are doing! beware. they contradict themselves and are poorly run and unethical. their knowledge and accuracy are bad. also, they are very money hungry, charging the consumer 4 times as much or more then the cost.

Hair Analysis: Why We Use Analytical Research Labs

Posted by Eileen Durfee on 22nd Mar 2015

Get your  Hair Analysis test and Nutritional Balancing program to determine the toxic metals and mineral imbalances in your body! This will help guide a corrective program customized to enhance your health. This is the most affordable and reliable method for precise results that will lead the way to a healthier life.  All of the Hair Analysis tests purchased through us are processed by  Analytical Research Labs and reviewed by  Dr. Lawrence Wilson . 

Why we recommend Analytical Research Labs

There are several factors that contribute to why Analytical Research Labs is the most  recommended for processing Hair Analysis tests:

• They do not wash the hair samples at the lab

For the most complete analysis, it is necessary that the hair  is not washed in the lab before testing. The results can vary when the washing agents and chemicals remove natural minerals from the hair. 

• Dr. Eck’s ideal ratios and levels are used

Analytical Research Labs provides a full Hair Analysis test interpretation based on Dr. Paul Eck's methods. This includes information about energy levels, carbohydrate tolerance, autonomic balance, metabolic trends, diet guidelines, metabolic rate, sugar tolerance, immune system, glandular activity, and a customized supplement program.

• Personalized Dr. Wilson program

All Hair Analysis tests processed with Analytical Research Labs include a Dr. Wilson created and customized program based on your personal lifestyle and diet to provide the most successful and accurate outcome.

A criticism may be made that other research labs point out more toxic elements than Analytical Research Labs. However, ARL does not review more toxic metals than are necessary to help create a corrective program. They analyze and report only the essential information in order to keep the costs low and lead the way with the most accurate Nutritional Balancing Science program possible.

The Validity of Hair Analysis

Home » Newsletters » The Validity of Hair Analysis

Clients and other health professionals at times ask for proof of the validity of hair mineral test­ing. There are at least three issues to consider: the validity of the testing procedure, the significance of the results and the validity of supplement programs based upon the readings.

Validity Of Mineral Testing

Spectrographic analysis is the standard method used for determining the mineral content of soil, rocks, tissue samples and other mineral-contain­ing materials. Anyone knowledgeable in chemical analysis is aware this technique is used at every university and in thousands of private laboratories across the nation.

Tissue mineral analysis is performed at Ana­lytical Research Labs (a.k.a. Accutrace Labs) via a computer-controlled inductively coupled plasma (ICP) instrument. This is a standard testing instru­ment used throughout the world.

Accutrace replaced their Perkin Elmer Elan 9000 ICP Mass Spectrometer with the Perkin Elmer NexION 2000 ICP-MS. ICP instrumentation is faster and can analyze more minerals. Accutrace Laboratories is licensed by the federal government and is inspected annually. Blind samples must be submitted that are within standard limits.

Accuracy also depends upon careful attention to the testing procedure and the kind of controls that are run with each batch of samples. Control samples are test samples in which the values are known in advance.

At Accutrace Labs, three sets of controls are run at the beginning and end of every batch of samples, every day. If any of the readings of the controls are not within strict guidelines, the entire batch of results is discarded. The instrument is recalibrated and the batch is rerun. We know of very few laboratories that go to this much trouble to make sure every reading is accurate.

Hair Analysis Studies

One study in the Journal of the AMA , August 23/30, 1985, Vol. 254, #8, pp 1041-1045 ques­tioned the validity of the testing procedure for hair analysis. Supposedly, similar samples were sent to 13 laboratories. Results varied between several of the laboratories. On this basis, the author felt that hair analysis was a "fraud".

• Long hair was cut up and mixed by hand for the samples. Mechanical mixing of hair sam­ples to produce a homogenous sample is very difficult, if not impossible.
• After cutting, hair was washed under the tap before being cut up. This is a violation of sampling protocol. Hair should not be washed at home after being cut and especially not in tap water.
• Some hair analysis laboratories wash the samples in various chemicals including water, detergents and acetone for varying lengths of time. This creates some variations in the readings. These differences were ignored in the study. We do not wash the sample before testing.

Any one of these problems would discredit the study. Together they make it basically useless.

For those who like scientific studies, however, the U.S. Environmental Protection Agency reviewed over 400 studies of hair analysis in 1979. The reviews involved mainly toxic metals. The EPA concluded that "hair is a meaningful and representative tissue for biological monitoring for most of the toxic metals." This 300-page docu­ment is entitled Toxic Trace Metals in Mam­malian Hair and Nails , EPA-600 4.79-049, August 1979.

Significance Of The Readings

What do hair analysis readings mean? This is a more difficult question. Our test interpretation is based upon original research by Dr. Paul Eck.

Dr. Eck synthesized many modern biological concepts to arrive at his interpretation methods. These include general systems theory, retracing theory, theory of biological transmutation (Louis Kervan), biochemical individuality (Roger Williams), the oxidation types (Dr. George Watson), the stages of stress (Dr. Hans Selye) and the mineral system (William Albrecht).

There have been a few scientific studies of hair analysis interpretation. One article appeared in the Journal of Orthomolecular Medicine , Vol. 1, #2, 1986. This article compared physical signs and symptoms in a group of patients with their oxidation type according to a hair analysis. The study found good, though not perfect correlation. This same journal is a good source for other hair analysis studies.

Regarding the significance of the readings, the best answer is the concepts and principles of interpretation we use correlate well with physical signs and symptoms. They allow us to predict symptoms accurately and are certainly subject to refinement by future researchers. This is the nature of scientific research.

Diet And Supplement Programs Based Upon Hair Analysis

It is one thing to interpret a hair test. It is another thing to offer a protocol for correction of imbalances. This area is even more empirical. Dr. Eck based his work on that of many other clini­cians, including Dr. George Watson, Dr. Carl Pfeiffer, MD PhD and many others who spent years designing clinical regimens to correct body chemistry. Quantities of foods, dosages of supplements, frequency of dosages and other factors are all empirical and individual in nature. The only proof of the validity of any such regimen is its effectiveness.

In summary, there is no question about the validity of hair mineral testing. The interpretation method is rather complex. We can say that the program has helped thousands of people. Ulti­mately, you must experience the program for yourself to determine its validity for you.

Could AI signal the end of the use of lab rats in research? Olden Labs reveals all

29-Apr-2024 - Last updated on 29-Apr-2024 at 11:23 GMT

• Email to a friend

Using artificial intelligence (AI), genetic engineering, and robotics, the company said it proudly introduces the world’s first automated animal research lab.

Founded by a team of experts spanning diverse disciplines, including a Harvard PhD biologist, a Forbes 30 Under 30 AI developer, and engineers from 10X Genomics and Apple, Olden Labs stands backed by supporters such as CHMBR Partners, Healthspan Capital, and the Mercatus Center’s Emergent Ventures.

“Animal research has been a cornerstone of therapy development, yet it has seen limited innovation,” remarks Michael Florea, co-founder, and CEO of Olden Labs.

“Many current methods are relics of the 1960s, while biologists revel in terabytes of digital data, animal studies remain entrenched in manual processes, often relegating results to paper. It became evident that bridging this technology gap could yield profound societal benefits.”

Animal testing ineffective and costly

Olden’s emergence aligns with a pivotal moment in legislative history, where a new US law eliminates the requirement for drugs in development to undergo testing in animals before human trials. Advocates for animal rights have long championed such a move, arguing that animal testing can be both ineffective and costly.

Dating back to the 18th century, laboratory rats have played a pivotal role in scientific research, from studies on digestion to advancements in physiology, pharmacology, and toxicology.

This legislative shift comes at a time when over $36 billion is annually allocated to animal studies, yet a staggering 90.4% of new drugs fail in human clinical trials. The archaic nature of animal research, characterized by high costs, low reproducibility, and poor data quality, necessitates a paradigm shift.

Real-time monitoring of animal health and behavior

Olden Labs, with its trifecta of innovative technologies encompassing robotics, AI, and gene delivery, aims to revolutionize animal studies. Their pioneering product, DOME smart cages, equipped with AI capabilities, offers real-time monitoring of animal health and behavior, providing researchers with a comprehensive understanding of their subjects' well-being.

“Labs across the U.S. utilize 111 million rodents annually, with upkeep costs exceeding $16 billion,” explains Charles Hirschler, managing member of CHMBR Partners, L.P., Olden Labs’ lead seed investor.

“Having experienced firsthand the challenges of traditional animal research, coupled with the rapid advancements in AI, robotics, and data acquisition, Olden Labs presents a unique opportunity to address these pressing needs.”

Voices as well as Olden Labe within the pharmaceutical sector have echoed these sentiments, highlighting the shortcomings of animal testing.

Prototyping analytical devices with three-dimensional (3D) printing techniques is becoming common in research laboratories. The attractiveness is associated with printers’ price reduction and the possibility of creating customized objects that could form complete analytical systems. Even though 3D printing enables the rapid fabrication of electrochemical sensors, its wider adoption by research laboratories is hindered by the lack of reference material and the high “entry barrier” to the field, manifested by the need to learn how to use 3D design software and operate the printers. This review article provides insights into fused deposition modeling 3D printing, discussing key challenges in producing electrochemical sensors using currently available extrusion tools, which include desktop 3D printers and 3D printing pens. Further, we discuss the electrode processing steps, including designing, printing conditions, and post-treatment steps. Finally, this work shed some light on the current applications of such electrochemical devices that can be a reference material for new research involving 3D printing.
