To help identify the cause of your symptoms, our naturopathic doctors can order a wide range of tests. These can include blood tests through lifelabs, or functional testing through a wide variety of labs. Lab tests are always recommended based on your individual health history. Keep reading to learn about the three tests our naturopathic doctors recommend most often:


IgG Food Sensitivity Testing


How is the test performed?

An easy in-office blood test.

Why is it tested?

Food sensitivity testing may be recommended if you experience chronic digestive complaints such as bloating, heartburn, constipation or diarrhea. Other symptoms of food sensitivities include weight gain, water retention, headaches and skin concerns such as eczema or acne. 

What is tested?

This test looks at the immunoglobulin G (IgG) antibodies to 94 of the most commonly eaten foods. Eating these foods can increase IgG levels. IgG can bind the food, creating an antigen-antibody complex that is deposited in tissues. This can increase inflammation and cause a wide variety of symptoms. It is important to note that food sensitivities are distinct from food allergies, which are caused by immunoglobulin E (IgE).

Post Menopause Hormone Panel


How is the test performed?

This is an at-home saliva test. Only 1 sample is required.

Why is it tested?

Hormonal imbalances can be the cause of hot flashes, sleep disruption, fertility challenges, fatigue, irregular cycles, mood changes, acne, weight changes, low libido, and migraines.

What is tested?

Estrogen is important for the maintenance of healthy bones and vaginal tissues. Low levels of estrogen may cause depression, low libido, fatigue and hot flashes. This test looks at three unique forms of estrogen; estrone, estradiol and estriol. Elevated levels of estradiol and estrone in postmenopausal women may be linked to an increase in breast cancer risk. 

In the menopausal period progesterone plays an important role in calming the nervous system. For many women, sufficient progesterone is the key to a good night’s sleep. 

Often viewed as ‘the man’s hormone’ testosterone has a role to play for women as well. Too much can cause facial hair growth, acne, and libido changes. Too little and women may struggle to gain muscle or experience fatigue, low libido, weight gain, and insomnia. 

Dehydroepiandrosterone (DHEA)
This test looks at two forms of DHEA. These are DHEA and the form bound to a sulphur molecule, DHEA-S. In postmenopausal women, 100% of estrogen is made from DHEA. As a result, testing DHEA can provide a fuller picture of her hormonal health. In addition, healthy DHEA levels may play a role in preventing depression, cardiovascular disease, and osteoporosis.

Thyroid Panel


How is the test performed?

This test is a simple blood draw done in our clinic. 

Why is it tested?

Many men and women in British Columbia have thyroid concerns. These vary from autoimmune conditions such as Hashimoto’s disease to a mildly underactive thyroid, often linked to long term stress. 

Decreased thyroid function is seen most commonly in British Columbia. This may present as weight gain, fatigue, recurrent miscarriages, dry skin, constipation, always feeling cold, heavy or irregular menstrual periods, thin hair, depression or a swollen thyroid gland. 

What is tested?

This hormone is the signal sent from your brain to your thyroid gland to promote the formation of thyroid hormone. 

Free T4
This hormone is produced by the thyroid gland in response to TSH stimulation. It’s less active than T3.

Free T3
T3 is made from T4. This occurs mostly in the liver, thyroid, and kidneys. 

Thyroid peroxidase antibody, TSH receptor antibody, Thyroglobulin antibody
One or all of these tests may be included to test for autoimmune thyroid conditions.
