A comprehensive nutritional analysis will help you achieve a well and healthy being!
Many preventable problems show up in blood, hair, stool and other biological tests long before you are actually ill. Certain tests, when read properly, will indicate if you are progressing towards a serious illness, such as cancer, liver, heart or many other diseases. Conversely, these tests can also confirm if you are eating and supplementing appropriately.

Common Testing Profiles

  • Comprehensive Blood Chemistry
  • Cardiovascular Risk Profile
  • Fatty Acid Test
  • Heavy Metal Test
  • Comprehensive Stool Analysis
  • Allergy (Cytokine Mediator-LEAP) Testing
    (see below for more information)

Wouldn't it be better to stop problems before they become serious?
Starting with a comprehensive health history followed by specific laboratory testing, we do an in-depth analysis of your total system. We see the problem areas and carefully note major and minor conditions that may lead to serious illness.

Sometimes an individual case may call for specialized testing, such as tissue mineral analysis, urinalysis, food allergy or other testing in order to determine exactly where there may be problem areas.

We will provide a detailed report explaining what the tests mean, all the nutrients, vitamins, dietary requirements, as well as any other changes that may be necessary to optimize the blood values and make you healthier.

How do we know our recommendations will work for you?
We retest to determine your progress. When you follow our plan exactly as recommended, significant change is almost always the end result.

You will then know specifically what your needs are in order to feel healthy and function at your peak.


Allergy Testing

Alcat LogoThe ALCAT Test differs from other food allergy or intolerance tests as it accurately and objectively measures leukocyte cellular reactivity in whole blood, which is a final common pathway of all mechanisms. The test utilizes electronic, state of the art, hematological instrumentation. Standard allergy tests, such as skin testing or RAST are not accurate for delayed type reactions to foods and chemicals. They measure only a single mechanism, such as the effect of mast cell release of histamine or the presence of allergen specific IgE molecules. Delayed reactions to foods and chemicals are NOT IgE mediated.

Symptoms of food sensitivity can include headache, indigestion or heartburn, fatigue, depression, joint pain or arthritis, canker sores, chronic respiratory symptoms such as wheezing, sinus congestion or bronchitis and chronic bowel problems such as diarrhea, constipation and even obesity.

The ALCAT Test also differs from standard IgG tests in that they rely exclusively on one immune pathway, serum levels of immunoglobulin G (IgG). In fact, high food specific IgG titers are indicative only of exposure, not necessarily intolerance.

The ALCAT Test reproducibly measures the final common pathway of all pathogenic mechanism; whether immune, non-immune, or toxic. It is the only test shown to correlate with clinical symptoms by double blind oral challenges, the gold standard.

Blood Testing

Our mission in terms of nutrition is to set a standard of objectivity in nutritional healthcare. We strive to help people reach their optimum health so that they in turn, can reach their fullest potential in life.

This is done first through gaining a foundational understanding of an individual’s health by objective blood testing.

What is Comprehensive Nutritional Blood Analysis?

It is a verifiable way of documenting how healthy you really are. Not just how you "feel". Get the Facts...Don't guess about your health...

We offer a science based approach to nutritional healthcare. Have you ever been told that you are "fine" but still feel bad? Or maybe you really do feel that you are in perfect health. Many problems show up in the blood long before you actually "feel" symptoms. Did you know you can have 20% liver or kidney function left and still have virtually no symptoms? You can also have up to 30% bone loss before that loss is visible on X-ray. How do you know if you're truly healthy? Certain tests, when read properly, will indicate whether or not you are progressing toward a serious illness, such as cancer, liver, heart or many other diseases.

A complete Nutritional Blood Analysis will determine:
  • How healthy you really are
  • What problems are just beginning
  • What diseases you have
  • What and how many vitamins and nutrients you need
  • If the vitamins you are taking are working
Early Detection and Correction are the Keys to a Healthy Life

Many problems are identified in the blood long before you actually experience symptoms. Certain tests that are read and evaluated properly, will indicate that you are progressing towards a serious illness, such as cancer, diabetes, liver, heart, or many other diseases. Beginning with a diagnostic blood test, we perform an in-depth analysis of your total system. We identify the problem areas and carefully document major and minor conditions that may lead to serious illness.

Sometimes, an individual case may call for specialized testing, such as tissue mineral analysis, food allergy, or other testing in order to identify other problem areas.

When all of the test results are in, we will provide a personalized, detailed report. These reports contain a hard copy of all of your test results, an explanation of what these tests mean, and a complete list of the nutrients, vitamins, dietary requirements and other lifestyle changes necessary to start your journey back to health.

Monitor the diseases you have and what you are progressing toward.

Wouldn't it be better to stop these problems before they progressed into something serious? Or wouldn't it be great if you could get back to the state of health you were in before you became ill? Starting with a consultation, the doctor will determine the testing that should be done. Using bloodwork and other diagnostic tools, we do an in-depth analysis of your system. The testing will tell us where the problem areas are occurring or just developing. During your report of findings we will carefully note major and minor conditions that may lead to serious illness. This detailed report will explain your test findings, as well as the nutrient and dietary recommendations based upon your test results.

A testable way to know what supplements you need and if those brands are working for you.

How do we know our recommendations will work for you? What makes us different from other nutritionists? We TEST and then retest to determine your progress. There is no guess work...it is all in the testing.

So what tests are required?

Every person is different. So it really depends on your particular case.

What testing can I do through your office?

Any blood test, toxic elements assessments [blood, hair, and urine], urinalysis, EKG, Allergy testing, pulse oximetry, Dexa Scan bone density.

How long does it take to get the test results back?

If you do the testing through our office, it usually takes no more than one to two weeks to get all of the test results back and your personalized detailed report completed!

Can I get my blood work done through my other doctor?

Of course! You may get your blood work done through another doctor and forward a copy to us so we can put together your report.

Do You Take Patients Who Are Out Of State?

Yes, We can set up phone consultations and we have the ability to order the testing you need from anywhere in the United States. We do however, strongly recommended that you have a face to face consultation with the doctor at least once.

What makes you different from other "nutritionists" or "health professionals"?

We use scientific objective testing in our analysis and recommendations and we see objective results. Some of the diagnostic testing we use are blood testing, toxic and elemental hair testing, food allergy testing (ALCAT, Cytokine, and Elisa), DMSA urinary challenge, DEXA bone density scan, X-ray, MRI, and EKG. There are a lot of very questionable 'energy' techniques to determine diseases and conditions. Studies have shown they are no better than just guessing. We get our great results because we test and we use objective testing methods.

How long will it take before I start to see improvement in my health problems?

Understand that we don't have a cure for your problem whether it is a rash, sinusitis, diabetes, migraines, IBS, colitis, or cancer. Our goal is to get you healthier. Progress is the key and there should be some definite, objective improvement within about 1 to 2 months if what we are doing and recommend is going to work. Do you have 2 months? If you can give us 2 months and you really work and do what is needed, it is highly unusual that progress/improvement is not seen. Then the goal is to keep you improving on a consistent basis. Sometimes in extreme cases a 5-10% improvement in 2 months could the best that we can hope for but if you continue to improve 5-10% every 2 months for a year or so where will you be? Some patients take longer than others. We make no guarantees that you will have similar results to someone else who had a successful or remarkable recovery. Success is largely dependent upon compliance.

Nutitional Patient Success Stories



Amy Mally"I want to thank you so much for helping me achieve a healthy lifestyle. I am so thankful that you were able to pin point the foods that I should and should not be eating. From the first day I walked into your office I knew that my life would be different. I walked in at a weight of 225 pounds at 5’4”, and after 5 months of following the plan you set up for me, plus regular exercise, I walked out at 150 pounds. A total weight loss of 75 pounds! The plan was so easy… I just followed the meal plan for the first 5 weeks, adding in new foods every week, and exercising 5 days a week. The first week I lost 8 pounds! I stuck to the plan and my energy was through the roof. I slept better, I had more energy at work and I felt like I was starting to look on the outside how I was feeling on the inside. I also want to thank you for always being available if I had a quick question or concern. I am so very fortunate that I walked into your office that day… you have forever changed my life. I wake up everyday feeling and looking my absolute best because of you! Thank you so much : )"

"Your advice about taking Vitamin B-Complex and B-6 worked to stop the swelling in my legs. About a month after I started taking them the swelling in my legs stopped. The vacation to Lake Tahoe didn’t affect my legs either. We had a good time thanks to you. My doctor also appreciated your suggestion. Thank you very much for your advice."
Herman J. Letournease

"I just wanted to thank you for all that you have done for me. It is like once I went to your office and got your information, and then took nutrients and changed my diet based on reality, it really “saved my life”. I was really depressed and you changed not only me, but my attitude and how I feel about myself, and that is the most important thing to me in the world. THANKS AGAIN"
Matt Fuss

"I have less stress because I know what’s wrong. My new nutrients, knowledge and physical therapy from Dr. Marquis has made a world of difference. I have hope, energy, lost weight and feel better physically."
Ann Hurley

"Dr. Marquis’ gentle yet thorough technique brought immediate results and benefits. His ongoing treatment has been an education for me in anatomy and nutrition. I especially appreciate his exhortations that with proper care, the human body can remain healthy for longer than I had thought possible."
Julian Granados

"Dr. Dave,
BradleyI just wanted to send you a note to thank you for all of your help and guidance regarding Bradley. I know we aren't completely out of the woods, but just since we have up-ed his iron with the supplements you suggested his coloring has turned beautiful and he looks and feels so healthy! Actually, he has never looked this good! I hope you can open these pictures. The first one was taken in March just a few weeks into starting the the LEAP program. The second picture I took today after church. The difference is remarkable and I am so full of gratitude. Between the diet and supplements (and lots of prayer), his improvement is nothing short of a miracle. Thank you again. I'm sure we will be in touch in the next few weeks. Have a great week."
Holli Wyett

"My story of health issues began when I was 19 years old. I was diagnosed with fibromyalgia, major depressive disorder, an anxiety disorder, some sort of connective tissue disease and chronic fatigue syndrome. I have been on multiple prescription medication ranging from several anti-depressants, pain killers, anti-anxiety drugs, and sleep medication that had to be delivered to my door, handed to me and signed for because it was so strong and sold on the street as a date rape drug. The side effects of all these drugs were worse than the initial symptoms that I took them for. They affected my mood, my weight, my memory and my outlook on life in general. I felt that this was my lot in life; to carry around a huge pill holder (larger than my grandparents) and be drugged for the rest of my life. Two years ago, I was working part time at a vet clinic and maintaining my health as best I could when what I can only describe as a metaphorical truck hit me. I was experiencing fatigue that I have never experienced before. I felt that I was wearing one of those lead aprons that the dentist puts on you prior to taking X-rays. I felt heavy. Moving became difficult as did talking. Changing positions in bed was akin to a workout. My husband had to help me up from a lying position and walk me to the restroom on several occasions. I couldn’t think let alone move and felt trapped in my own body. This is when I was told I had chronic fatigue syndrome, was put on the narcotic sleeping drug, told to get lots of rest and kindly sent home. I had to quit my job and was put on disability. I was 35 years old.

Fate intervened this past January 2009 by way of a dental hygienist who heard me tell my tale of woe to my dentist whom I have known for many years. She told me about Dr. Marquis, how he helped her and gave me his card. I called his office that day. My husband and I went to my first appointment and I was very apprehensive. I had seen many doctors who either threw the arms up in frustration or threw the latest medication at me. I didn’t want to get my hopes up. Dr. Marquis put me at ease immediately and listened to my history. He was kind, understanding and very matter of fact about getting me better. In fact, his confidence in my health improving was quite surprising to me. After he found abnormalities in my lab work that no other doctor had bothered to check for, he started me on several supplements and a specialized diet. I followed his orders but didn’t want to be disappointed again, so I really didn’t notice the subtle yet profound improvements. It started with not having to nap during the day. That was huge for me. Not only could I stay awake, I could make conversation and do housework. The lead apron began to lift and I found myself with more energy. I was very careful with what I did as I didn’t want to jinx anything and end up back at square one. I found that my energy kept growing and I could take on more activities without feeling the after effects like I had before. I was able to socialize with friends again, take my dog for a walk and start exercising regularly. My joints stopped hurting. My skin became softer. My mood stabilized. I felt well enough to start school again and get back to the gym. Last week, I walked for 60 minutes on the treadmill and as the digital clock inched past 59 minutes, I started to cry out of pure joy. Sure, I felt a little silly about crying at the gym, but I didn’t care. I didn’t think this was possible for me. It was a year ago that my husband had to help me to the bathroom and here I was, working out, sweating and feeling good for the first time in years.

I am happy to report that my energy continues to sustain me throughout the day. I am no longer scared to try a new physical activity for fear that I will be stuck in bed the next day. I am experiencing no pain, which is remarkable as I have had deep joint pain for almost 20 years. I am no longer on any prescription medication. My body is not my enemy anymore. In fact, I am experiencing life as I never have and it is wonderful.

Words cannot express my gratitude for Dr. Marquis. He saved my life from being filled with doctor visits, a slew of prescription medication and a myriad of detrimental side effects. I am so very grateful for his expertise, his compassion and his commitment to improving lives. I credit him with improving not only my physical body, but also my emotional well-being. With his help, I have hope again and am looking forward to a future of fun and adventure without the weight of the world holding me down anymore."
