Diagnostic testing

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 Genetics

  • The Methylation Panel, which gauges methylation metabolites and genetic single nucleotide polymorphisms (SNPs) via buccal swab, serves as a comprehensive assessment of the biochemical methylation pathway. The panel includes testing for the MTHFR gene, shedding light on its role in detoxification, mood regulation, 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.

Oats –

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”

    In October of 2015 I was debating on competing in my second NPC Championship. Even before I decided to do the show I knew for sure who I was going to call to be my prep coach and handle my diet and workouts. That would be Jamie Speiser at Precision Fitness and Spa. I t was a little over 3 years since my first competition and I have always followed Jamie on social media and it was apparent of the success he had with his clients. Every competition picture that got posted had him standing with his athlete with a medal around their neck! There are many things, but one thing that stuck out with Jamie is that he sincerely cares about his clients and wants them to succeed as bad as they want too themselves! In my 4 months of prep I went from 11.6% body fat to just under 4% and I gained several pounds of muscle in the process (And oh by the way, I was 48 years old for this competition and I took 1st place in my masters class!) If I were to do another show; he'd be my Go To coach, no doubt about it!!!

    WOW !! GREAT !! TEAM WORK!!! POSITIVENESS !!!! SUPPORTIVE !!! ENCOURAGEMENT!!! YOU MEAN SOMETHING !!!!! WELL INFORMED!!! LIFE CHANGING !!!! These are just a few words that I experience working with Precision Fitness and SPA each day. Jamie Speiser and his staff are all of these and more and have kept me going through all the struggles and over the hills when the tough times have come. Before starting with Jamie I was the type of person that each day was from the chair to car to chair at work, back to car back to the couch. I was on oxygen at work and home, multiple medications my health and lifestyle was in a fast track to going to a fast end. My weight and condition was the "elephant in the room" that no one wanted to bring up to me as they didn't want to hurt me or my feelings. Then two people who changed my life and asked if I would meet someone that might be able to help me and they introduced me to Jamie Speiser. UNBELIEVABLE DAY FOR ME. HE OPENED THE WORLD BACK TO ME AND GAVE ME BACK MY LIFE. The simple things that people take for granted to be able to sit in a regular chair to watch your granddaughter dance. Be able to walk and play catch, go to the pool to go swimming, able to shovel your own snow and cut your own grass. All lift changing >>>>> I can go on forever about the numbers and the loss in lbs and inches ( which is awesome). The major changes I have experienced is the awareness I have gotten from Jamie and everyone at Precision Fitness and the courage and knowledge of making good healthy decisions at each meal. The challenging work-outs are tough but are adjusted to meet everyone's needs and abilities. They are fun and challenging the staff keep you wanting more and wanting to come back. Jamie Speiser , and the staff at Precision Fitness is a place that everyone can feel at ease. I hope everyone will come and try it for themselves.
