Understanding your internal health through advanced biomarkers is one of the most effective ways to move from reactive care to truly proactive, preventative medicine. Comprehensive health assessments allow us to identify subtle imbalances long before they develop into more serious conditions, giving you the opportunity to intervene early and strategically.
Contents show
As part of my lab testing as an Ontario naturopath, I routinely use a broad range of evidence-based laboratory investigations to assess hormone balance, metabolic function, nutrient status, inflammation, and organ health. Many of these biomarkers are either not routinely ordered, not interpreted in depth, or simply not available through other doctors in standard primary care settings. This allows for a more complete and nuanced understanding of your physiology.
These tests are particularly valuable during annual health assessments, where the goal is not just to confirm that everything is “normal,” but to evaluate whether your body is functioning optimally. They are also essential if you are experiencing symptoms such as fatigue, hair loss, irregular periods, acne, digestive concerns, weight changes, or fertility challenges. Even in the absence of clear symptoms, comprehensive testing can uncover early warning signs of conditions such as insulin resistance, thyroid dysfunction, or chronic inflammation.
A key advantage of working with a naturopathic doctor is access to a wider scope of testing. If you have ever wondered what tests a naturopathic doctor can order in Ontario, the answer is extensive. Under provincial regulations, naturopathic doctors are authorized to requisition a wide array of laboratory tests across multiple specimen types, including blood, urine, stool, and more. This enables a more thorough investigation compared to standard screening panels.
My clinical approach is both thorough and highly individualized. Rather than ordering excessive or unnecessary testing, I select biomarkers strategically based on your health history, symptoms, and goals. Each test is chosen with a clear purpose: to either confirm a suspected imbalance, rule out potential concerns, or guide targeted treatment decisions. Results are then interpreted in context, not in isolation, allowing for a more accurate and clinically meaningful understanding of your health.
Ultimately, this approach supports a more proactive and preventative model of care. By identifying and addressing imbalances early, we can reduce the risk of chronic disease, improve day-to-day well-being, and support long-term health outcomes.

181
Progesterone — Saliva
Salivary progesterone reflects the free, tissue-available fraction of progesterone; particularly useful for detecting luteal phase insufficiency and guiding hormone support therapy.
182
Testosterone — Saliva
Measures the free, bioactive fraction of testosterone in saliva; a non-invasive and practical way to assess androgen status for libido, energy, mood, and muscle function concerns.
183
Testosterone (Free) — Saliva
Specifically isolates the unbound, biologically active testosterone in saliva; considered a clinically meaningful measure of androgen sufficiency, particularly in women.
Tests Performed on Hair
1 TEST184
Heavy Metal — Hair Element Analysis
Analyzes a small hair sample for a broad panel of toxic heavy metals and essential minerals, providing a long-term record (months) of elemental exposure and mineral status that blood or urine cannot capture.
Tests Performed on Tissue, Discharge & Sputum
8 TESTS184.1
Cervicovaginal Cellular Evaluation (Pap Smear)
Examines cells from the cervix for abnormal changes caused by HPV or pre-cancerous transformation; the primary screening tool for cervical cancer prevention.
185
Culture — Throat Swab for Streptococcus Screen
Identifies the presence of Group A Streptococcus in the throat; used to confirm strep throat and guide the decision to use antibiotics versus watchful waiting.
186
Culture and Sensitivities — Other Swabs or Pus
Grows bacteria from wound, skin, or discharge samples and tests which antimicrobials can effectively treat the infection, enabling targeted therapy.
187
Culture and Sensitivities — Sputum
Identifies bacteria or fungi in coughed-up respiratory secretions and determines antibiotic sensitivity; essential for diagnosing pneumonia and lower respiratory tract infections.
188
Nail and Skin Cultures
Identifies the specific fungal species causing nail or skin infections (e.g., tinea, onychomycosis) and guides selection of the most effective antifungal treatment.
189
Nasal Swabs (Culture and Smear)
Detects bacterial colonization or infection in the nasal passages, including MRSA screening and respiratory pathogen identification.
191
Seminal Fluid Examination (Complete)
Evaluates sperm count, motility, morphology, volume, and other parameters; the foundational test for assessing male fertility and reproductive health.
191.1
Smear Only — Gram or Papanicolaou Stain
Prepares and stains a specimen to classify bacteria by cell wall type (Gram stain) or identify abnormal cells (Pap stain), providing rapid diagnostic direction before culture results are available.
Tests Performed on Breath
3 TESTS192
Hydrogen Breath Test
Measures hydrogen and methane gas exhaled after ingesting a sugar solution; elevated levels produced by gut bacteria indicate carbohydrate malabsorption (e.g., lactose or fructose intolerance) or small intestinal bacterial overgrowth (SIBO).
193
Intestinal Permeability Test
Uses orally ingested sugar molecules of different sizes to measure how much passes through the gut wall into urine; an objective functional assessment of “leaky gut” (increased intestinal permeability).
194
Urea Breath Test for H. pylori
Detects active Helicobacter pylori infection in the stomach by measuring labelled carbon dioxide in exhaled breath after ingesting urea; a non-invasive, highly accurate test for this ulcer-causing bacterium.
Frequently Asked Questions About Advanced Lab Testing
What are these tests, and why would I need them?
These are comprehensive biomarker-based health assessments designed to evaluate key systems in the body, including hormones, metabolism, inflammation, and nutrient status. Unlike basic screening labs, this type of advanced lab testing in Ontario with a naturopath is more thorough, proactive, and preventative, helping identify imbalances before they develop into more serious conditions.
What tests can a naturopathic doctor order in Ontario?
A licensed naturopathic doctor can order a wide range of laboratory and functional tests. These may include blood work, hormone panels, metabolic markers, and specialized testing that is often not available through other doctors or not typically offered in standard care. These tests provide deeper insight into your health and support more individualized treatment plans.
Do I need a reason or symptoms to get tested?
Not necessarily. Many patients pursue annual health assessments as part of a proactive health strategy. Others seek testing due to symptoms such as fatigue, irregular periods, fertility challenges, digestive issues, hair loss, or unexplained weight changes. Testing can be valuable both for prevention and for investigation.
How is this different from tests ordered by my medical doctor?
While conventional lab work is essential, it is often focused on diagnosing disease. Naturopathic lab testing tends to be more preventative and functional, assessing optimal ranges rather than just disease thresholds. It may also include biomarkers that are not routinely tested in standard care.
What is the process for getting tested?
The process is straightforward. After an initial consultation, your naturopathic doctor will recommend appropriate biomarkers and lab testing based on your health history and goals. You will then complete the testing through a licensed lab. Once results are available, Dr. Pamela Frank, Naturopath, will review them with you and create a personalized plan.
Do I need a referral?
No referral is required to undergo testing through a naturopathic doctor in Ontario. You can book directly for an initial naturopathic health assessment and testing recommendations.
How much do these tests cost?
Costs vary depending on the type and number of tests ordered. Basic panels may be relatively affordable, while more comprehensive or specialized testing can be more expensive. Some tests may be covered through OHIP if ordered through a medical doctor, while others are paid out of pocket. You will always be informed of costs in advance.
Are these tests covered by insurance?
In Ontario, lab tests ordered by a naturopathic doctor are not covered by OHIP. However, many extended health insurance plans cover naturopathic consultations, which can offset overall costs. Health spending accounts will usually cover lab tests. Some insurance plans may cover lab tests under the category of “lab testing,” “medical testing,” or “diagnostic testing.” Some will cover tests, but NOT if OHIP would have covered them if they were ordered by your doctor. Check with your insurance company.
How often should I do this type of testing?
For many patients, annual health assessments are appropriate. Others may require more frequent monitoring depending on their condition, treatment plan, or health goals.
What happens after I get my results?
Naturopathic doctor Pamela Frank will interpret your results in detail with you, looking at patterns and root causes. From there, you will receive a personalized, evidence-informed plan that may include nutrition, lifestyle strategies, and targeted supplementation to optimize your health.
Is this approach evidence-based?
Yes. A qualified naturopathic doctor, like Dr. Frank, uses clinically relevant biomarkers alongside current research to guide recommendations. The goal is to combine scientific evidence with a thorough, individualized approach to care.
Is this testing right for me?
If you are looking for a more proactive, preventative, and comprehensive understanding of your health, this approach may be a strong fit. It is especially helpful for individuals who feel their concerns have not been fully addressed or who want deeper insight into their overall health status.
