Specialized Testing
Specialized laboratory testing can extend an assessment beyond routine blood work. Available options include selected exposure, metabolic, infection and genetic tests, with no specialist referral required.
A Broader Range of Testing Options
Some patients want to investigate concerns that are not included in routine blood work, or have persistent symptoms despite previous medical assessment. Private testing offers access to additional laboratory options and more time to review what each test measures.
Routine medical testing remains important and should not be replaced when primary care, imaging or specialist assessment is needed. Specialized panels can be considered alongside that care, with their costs, evidence and limitations explained before ordering.
What Specialized Testing May Assess
Specific metals or environmental chemicals when there is a relevant exposure history
Organic acid measurements that provide a descriptive metabolic profile
Targeted antibody, antigen or molecular testing based on symptoms and exposure history
Variants such as MTHFR, interpreted with health history and related blood markers
Specialized Testing Options
Dr. MacLeod reviews your previous results, health history and testing priorities, recommends suitable options and discusses any additional panels you want to consider.
Heavy Metal Assessment
Measures selected elements such as mercury, lead, arsenic or cadmium. The specimen and interpretation depend on the element, the suspected source and the timing of exposure.
Consider when: There is a relevant environmental or occupational exposure
Organic Acids Test (OAT)
Measures a range of metabolites in urine. The pattern may provide supplementary information about metabolic pathways, but it does not diagnose a specific cause of fatigue or other symptoms on its own.
Consider when: A broader metabolic profile is requested after initial assessment
Chronic Infection Panels
Targeted testing may include Epstein-Barr virus, Lyme disease or other infections. The type of test and timing are selected according to symptoms, exposure history and previous results.
Important: Positive and negative results require clinical interpretation
Environmental Toxins
Some private laboratories measure metabolites associated with selected pesticides, plasticizers or solvents. Availability and the clinical usefulness of individual markers vary.
Consider when: There is a specific exposure concern to investigate
Methylation Panel
May combine selected genetic variants with blood markers such as homocysteine, folate and vitamin B12. A genetic variant does not by itself diagnose impaired metabolism or determine treatment.
Interpretation: Results are reviewed with related blood work and health history
A Broader Assessment for Complex Histories
Persistent or multi-system symptoms often require information from several sources: medical history, physical examination, routine laboratory work, imaging or specialist assessment, and sometimes additional private testing.
Specialized tests can add another layer when you want to investigate a particular exposure, infection, metabolic profile or genetic variant. Their findings are reviewed alongside established tests rather than treated as a complete explanation on their own.
Dr. MacLeod will explain which options fit your priorities, what the results can and cannot establish, and the cost before you decide how broad you want the assessment to be.
When to Consider Specialized Testing
- Routine blood work has not explained persistent symptoms
- Chronic fatigue that doesn't improve with rest or lifestyle changes
- Multiple symptoms across different body systems
- History of environmental or occupational exposure
- Post-viral symptoms that haven't resolved (long COVID, post-EBV)
- Family history of autoimmune, neurological or metabolic conditions
Concerns to Review During Your Consultation
Neurological & Cognitive
- Persistent brain fog or poor memory
- Numbness, tingling or neuropathy
- Mood swings, anxiety or depression
- Difficulty concentrating
- Headaches or migraines
Systemic & Physical
- Chronic fatigue unresponsive to treatment
- Joint and muscle pain without clear cause
- Chemical sensitivities or medication reactions
- Hormonal issues despite standard treatment
- Recurrent infections or immune dysfunction
- Symptoms that started after an illness or exposure
Accessing Specialized Testing in Nova Scotia
Publicly funded testing and private laboratory testing serve different roles. Primary care and specialist pathways provide essential diagnostic assessment, while private laboratories can offer additional tests that are not routinely funded or are difficult to access through the public system.
- No family doctor or specialist referral is required to discuss private testing through the practice
- Available options, expected costs and collection instructions are reviewed before ordering
- Additional tests you want to explore can be discussed as part of the testing plan
Specialized testing complements rather than replaces conventional care. Results that require medical diagnosis, imaging, urgent assessment or specialist treatment are directed to the appropriate healthcare service, and copies can be shared with your existing providers.

Frequently Asked Questions
Can I request a specific specialized test?
Yes. Bring the name of the test or the area you want investigated to your consultation. I will explain the available options, recommend a suitable testing plan and review the cost and limitations with you before anything is ordered.
How much do specialized tests cost?
Costs vary by laboratory and panel. The complete price is reviewed before ordering so you can decide whether to proceed with a focused test or a broader assessment. Some extended health plans may provide partial laboratory coverage.
How reliable are specialized tests?
Reliability and clinical usefulness vary by test. Laboratory accuracy does not always mean that every reported marker has a well-established role in diagnosis or treatment. I will explain the evidence and limitations that apply to the testing you are considering.
Should I start with routine blood work or specialized testing?
Routine blood work often provides important baseline information and may be completed before or alongside specialized testing. The order depends on your previous results, symptoms, exposure history and the testing you want to pursue.
Can you work with my existing healthcare team?
Yes. Specialized testing can complement care from your family doctor, specialist or other healthcare providers. You can receive copies of your results, and findings that require medical investigation or treatment can be shared with the appropriate provider.
