Complete Thyroid Testing

Standard TSH testing misses up to 7% of thyroid disorders. We offer comprehensive thyroid panels that reveal the full picture, including markers most doctors don't order, without a family doctor requisition.

Why Standard Thyroid Testing Falls Short

If you've been told your thyroid is "normal" but still experience fatigue, weight gain, brain fog or cold intolerance, you're not alone. Standard testing typically only includes TSH, and sometimes Free T4, missing critical markers that reveal the full picture.

TSH is like checking the thermostat without checking if the furnace is actually working. It tells us how hard your pituitary is signaling your thyroid, but not how well your thyroid is responding, whether you're converting T4 to active T3 or whether your immune system is attacking your thyroid.

What Standard Testing Misses

Conversion problems

Normal T4 but poor conversion to active T3

Reverse T3 dominance

T4 converting to inactive rT3 instead of active T3

Early autoimmune disease

Antibodies attacking thyroid years before TSH changes

"Normal" but not optimal

TSH in range but not where you function best

The Complete Thyroid Panel

We test all the markers needed to understand your thyroid function, not just the basics.

TSH

TSH

Thyroid Stimulating Hormone: the pituitary's signal to your thyroid. Shows how hard your body is working to maintain thyroid levels.

Standard range: 0.4–4.5 mIU/L
Optimal range: 0.5–2.0 mIU/L
FT4

Free T4

The storage form of thyroid hormone. Your thyroid primarily produces T4, which must be converted to T3 to be used by cells.

Standard range: 0.8–1.8 ng/dL
Optimal range: 1.0–1.5 ng/dL
FT3

Free T3

The active thyroid hormone. This is what actually affects your cells, metabolism, energy and temperature regulation.

Standard range: 2.0–4.4 pg/mL
Optimal range: 3.0–4.0 pg/mL
rT3

Reverse T3

An inactive form of T3. High levels indicate your body is deactivating thyroid hormone, often due to stress, illness or inflammation.

Standard range: 10–24 ng/dL
Optimal range: 12–18 ng/dL
TPO

TPO Antibodies

Thyroid Peroxidase antibodies. Elevated levels indicate Hashimoto's thyroiditis,the most common cause of hypothyroidism.

Standard range: <35 IU/mL
Optimal range: <2 IU/mL
TgAb

Thyroglobulin Antibodies

Another autoimmune marker. Present in 20–90% of Hashimoto's patients. Some people have elevated TgAb without elevated TPO.

Standard range: <40 IU/mL
Optimal range: <2 IU/mL

Why Thyroid Antibodies Matter

Hashimoto's thyroiditis, an autoimmune attack on the thyroid, is the most common cause of hypothyroidism. Yet most people with Hashimoto's don't know they have it because antibody testing is rarely ordered.

Here's the problem: antibodies can be elevated for years before TSH becomes abnormal. During this time, you may experience classic hypothyroid symptoms, such as fatigue, weight gain, brain fog and hair loss, but be told your thyroid is "fine."

Finding elevated antibodies early matters because we can often intervene to slow or halt the autoimmune process before significant thyroid damage occurs.

Who Should Test Thyroid Antibodies?

  • Family history of thyroid disease or autoimmune conditions
  • Thyroid symptoms despite "normal" TSH
  • Other autoimmune conditions (celiac, RA, type 1 diabetes)
  • Fertility concerns or recurrent miscarriage
  • Postpartum thyroid symptoms
  • Thyroid levels that fluctuate or are difficult to stabilize

Optimal vs. "Normal" Ranges

Standard lab ranges are based on the general population, including people who are unwell. A "normal" result doesn't necessarily mean optimal function for you.

TSH Example

Standard Lab Range

0.4 – 4.5 mIU/L

A TSH of 4.0 would be considered "normal"

Optimal Functional Range

0.5 – 2.0 mIU/L

Where most people feel and function best

Many patients with a TSH of 3.0–4.5 experience hypothyroid symptoms but are told their thyroid is "fine." We use optimal functional ranges to identify when intervention may help, even if your numbers are technically "normal."

Signs Your Thyroid May Need Attention

Underactive Thyroid (Hypothyroidism)

  • Fatigue and low energy
  • Weight gain or difficulty losing weight
  • Cold intolerance
  • Constipation
  • Dry skin and hair
  • Hair loss
  • Brain fog and poor concentration
  • Depression
  • Muscle weakness
  • Heavy or irregular periods

Overactive Thyroid (Hyperthyroidism)

  • Unexplained weight loss
  • Rapid or irregular heartbeat
  • Anxiety and nervousness
  • Tremors
  • Heat intolerance
  • Increased sweating
  • Difficulty sleeping
  • Frequent bowel movements
  • Muscle weakness
  • Light or missed periods

Thyroid Testing Access in Nova Scotia

An estimated 1 in 10 Canadians has a thyroid disorder, and about 50% are undiagnosed. In Nova Scotia, accessing comprehensive thyroid testing can be challenging:

  • Many family doctors only order TSH, missing the broader picture
  • Wait times for endocrinology referrals can be months to years
  • MSI coverage is limited for comprehensive panels
  • Thousands of Nova Scotians don't have a family doctor at all

Through our practice, you can access complete thyroid testing without a family doctor requisition. Results are interpreted using optimal functional ranges, not just standard lab cutoffs and we develop actionable treatment plans based on your findings.

Getting Started

Complete thyroid testing includes TSH, Free T3, Free T4, Reverse T3 and thyroid antibodies (TPO and TgAb). Most extended health insurance plans cover naturopathic consultations.

Frequently Asked Questions

Do I need a doctor's requisition for thyroid testing?

No. As a naturopathic doctor, I can order comprehensive thyroid panels directly. You don't need a family doctor or specialist referral to access complete testing.

Is thyroid testing covered by MSI?

Testing ordered through a naturopathic doctor is not covered by MSI. However, many extended health plans cover naturopathic services. The lab testing itself is an out-of-pocket expense, but provides access to markers that are often not ordered through conventional channels.

When should I get my blood drawn for thyroid testing?

Thyroid testing is best done in the morning, ideally before 10 AM. If you're taking thyroid medication, draw blood before taking your morning dose. Fasting is not required but is often recommended if we're running other tests at the same time.

I'm already on thyroid medication. Can you still help?

Yes. Many patients on thyroid medication still don't feel optimal. Comprehensive testing can reveal whether your current medication is working effectively, whether you're converting T4 to T3 properly and whether there are other factors affecting your thyroid health. I work alongside your prescribing physician, not in place of them.

What if my antibodies are elevated?

Elevated antibodies indicate autoimmune thyroid activity, but it's not a death sentence. Research shows that addressing underlying factors, including gut health, nutrient deficiencies, gluten sensitivity and stress, can help reduce antibody levels in many patients. Early detection gives us the opportunity to intervene before significant thyroid damage occurs.
