Diagnostic testing

At Precision we have access to various resources that help us determine the cause of a patient’s symptoms or illness. It involves using medical devices and procedures to obtain information about a patient’s condition. Diagnostic tests include laboratory blood tests

The information gathered from diagnostic testing can be used to diagnose a disease or condition, monitor the progress of a disease or condition, and guide treatment decisions. Our testing allows us to take a deeper look and determine the appropriate treatment and care for patients, which can lead to better health outcomes.

Precision medicine uses advanced technologies such as testing to identify specific genetic markers, mycotoxins, OATs and hormone levels that may be responsible for a patient’s condition. This information can guide our team to develop personalized treatment plans that are more effective and tailored to the individual’s needs.

The goal of precision medicine is to provide more targeted and effective treatments, reduce side effects, and improve overall health outcomes for patients.

Genova Testing

Hormone balance

  • Genova offers saliva, urine, and blood testing to assess adrenal, thyroid, and sex hormones. Testing is appropriate for cycling females, peri- and menopausal females, and males.
  • Hormonal imbalance can result in fatigue, weight changes, menstrual irregularities, menopausal symptoms, low libido, memory issues, and others. Using hormone testing, clinicians can customize hormone and/or nutritional therapies.

GI Health

  • The GI Effects® Comprehensive Stool Profile provides valuable insight into digestive function, intestinal inflammation, and the intestinal microbiome. This profile can reveal important information about the root cause of many common gastrointestinal symptoms and non-GI conditions.
  • SIBO (Small Intestinal Bacterial Overgrowth) breath testing assesses hydrogen and methane gases to evaluate for SIBO or intestinal methanogen overgrowth (IMO).
  • Gut symptoms such as bloating, gas, diarrhea, and constipation are common with these conditions.

Methylation and Generics

  • The Methylation Panel offers insight into the biochemical methylation pathway. Methylation metabolites are measured in plasma and genetic single nucleotide polymorphisms (SNPs) are analyzed via buccal swab.
  • Methylation is important for detoxification, mood, cardiovascular health, and energy production.


Molds produce toxins known as mycotoxins. Molds are ALWAYS present in homes or workplaces that are water damaged and they are ALWAYS producing mycotoxins. Even small amounts of mold growth in the air conditioning or ducts will result in the occupants being chronically exposed, constantly breathing mold spores and their mycotoxins, resulting in illnesses.

It is well established in medicine and science that exposure to molds and mycotoxins indoors is hazardous, and more so in children and the elderly. How a person reacts to molds and mycotoxins depends on that person’s health status, if they have other health conditions, how long is or was the exposure, the person’s genetic makeup, and the nutritional status of the patient.

Traditional Lab testing provided through Precision labs, LabCorp and Quest
Using serum we are able to test a patient’s CBC, CMP, hormones, inflammation and more. We are able to provide laboratory testing for self pay patients and those who would like to use insurance. Please note that cost is determined by your insurance and testing needed.

Organic acids are products of the body’s metabolic pathways. Evaluation of these downstream metabolites from various metabolic pathways provides insight into important areas related to gut health, mitochondrial dysfunction, neurotransmitter status, indicators of detoxification and macronutrient breakdown and nutritional status. This makes organic acid testing a valuable tool to assess the functional need for essential nutrients, diet modification, antioxidant protection, detoxification, and other therapies.


The Dutch complete offers an extensive profile of sex and adrenal hormones and melatonin, along with their metabolites, to identify symptoms of hormonal imbalances. Easily collected in the comfort of your own home, samples are then sent to the lab to be processed.

Once we have all of the information about you and your unique bio individuality, we recommend research based treatments based on YOU and the root cause of your symptoms. We offer a variety of in-house treatments, services, and products, and refer you out when necessary to ensure that your treatment is successful. We evaluate your progress, and we support you over time as you take action to be your best self.

“Our valuable clients deserves the best”

I have been working with Jamie Speiser for 8 years now and my experience has been life changing. He has helped me in so many ways. Starting from dialing in on my nutrition for body building shows, to workout routines, to helping me find more natural ways to overcome health issues. I don’t know what my life would be like without all the work he has done for me over the years. I love his approach. He considers all aspects of life when working with me, from emotional states to the way my physical body is responding. He is supportive and very understanding. He will meet me where I am at and move me to the next level.
I am very grateful to be able to work with such an intelligent and experienced professional. Thank you Jamie for all your hard work throughout the years. It means so much to me.

Working with Precision Fitness over the last 7 months on my fitness and health goals has been transformational and an extremely positive experience!! We set goals for my 2022 Bikini competition and achieved all of them.

I am very excited to continue working with Jamie as my coach and Jake as my trainer to achieve the goals we have set out for 2023. I truly get excited anytime I need to go to Precision not only because they are great at what they do but they always greet you with a welcoming smile, are passionate about what they do, and truly care about you as an individual.

My husband and I own a baseball and training facility in Washington state where I work as a certified personal trainer and wellness coach, both in person and online, offering training and nutrition coaching for diverse populations and competitors. I continually seek to understand and evolve in my own knowledge by seeking out other professionals who can better equip me with tools to advance my own health and fitness/nutritional needs.

After recovering from recurring uti/kidney infections about 6 months ago and nearing the age of 50, I really wanted to address any nutritional and training issues that may also be contributing to barriers that were preventing me from reaching some personal goals. As a former and very successful competitor in the bikini athletic division I was struggling to lean out, even just a few pounds, had belly bloat, and had been struggling where it used to be fairly easy to get to my ideal body composition just to go on vacations or special events.

I discovered Jamie on TikTok discussing hormonal challenges as well as elimination/anti-inflammatory nutrition and immediately reached out to him because I knew I definitely could relate to many of the hormonal and nutritional pitfalls that could very well be working against me in my own programming. Jamie immediately booted me up on his structured elimination/anti-inflammatory nutrition program and detailed me on my hormones as well as designing a challenging new training program to gradually reduce the intensity of cardio that had been sabotaging my progress, and still provide me with training techniques to build and maintain muscle mass. We tracked everything through formal check-ins, pictures, scale weight, and InBody Scan to track my progress.

I began my program at 136.4 lbs, muscle mass = 63.7 lbs, and 16.0% body fat in mid June 2022. December 21, 2022 my progress translated to 132.2 lbs, muscle mass 65.7, and 11.6% body fat. While I feel these body composition changes are of themselves an outstanding progression for where I was at, the real rewards have been manifested in a diminished swelling in my lower abdomen, increased energy, and ZERO uti/kidney infections! I love the body composition that has “peaked” in just 6 months with Jamie’s program and I am eager to continue setting new goals and to continue working with the nutritional needs my body required to reach optimal levels in my fitness, health and nutritional goals

We’ve been working together since August 2018 and had great progress in numerous competitions. Here we are about to begin another journey in 2023 and I’m excited to start this year. Last year we found out I was insulin resistant. No matter what we did with food and workouts, body fat, especially around the midsection and back were not moving. You suggested we get some bloodwork done to see what my A1c and Insulin levels were. October 2021 we find that I’m insulin resistant and pre-diabetic. You worked hard to get the numbers down with different variations of food, but still no progress. I saw my family physician and he prescribed a low dosage of Metformin. I continued with the plan and new tests were accomplished to see if anything changed. PROGRESS, A1c and Insulin levels were down to where my physician wanted to take me off the medication. I know if I had not been working with you, I may not have found out I was pre-diabetic. Thank you for paying close attention to my numbers and making the suggestion to have bloodwork done. Thank you for listening. During my last check-in you noticed big changes in my numbers and I’m ready to continue the work. LET’S GO!!
