Laboratory Tests

At Meridian Spine + Sport, our naturopathic doctor Dr. Misa, offers a variety of laboratory tests that are not covered through OHIP, and therefore not available through your family MD.  These tests may assist in diagnosing the root cause of your health condition.

Call or email us for more information on whether these tests may be suitable for you.  Fees cover only the cost of the tests and do not include the cost of consultations with Dr. Misa.


Food Sensitivity Blood Test ($300 for 120 Foods, $425 for 200 Foods)

When the immune system reacts to a food that is ingested or inhaled, it releases cells called antibodies. The foods and inhaled particles that provoke the release of antibodies are called allergens. Two commonly produced antibodies are IgG and IgE.

If you are referred by your family MD to an allergy specialist, he/she will test for IgE reactions to foods. IgE is produced immediately after an allergic food is ingested or inhaled (called “anaphylaxis”) and will cause reactions such as hives, facial swelling and throat constriction.

Dr. Misa tests for IgG reactions to foods.  Symptoms of IgG food sensitivities (called a “delayed hypersensitivity response”) take hours or days to develop and because of this they are very difficult to identify without testing.  IgG testing requires a simple finger prick in the lab and takes only a few minutes.  The laboratory tests your blood for IgG antibodies to a variety of different foods.

An IgG immune response may cause symptoms/conditions such as:

  • Gas and bloating
  • Eczema and other skin conditions
  • Migraines
  • Recurrent ear infections in children
  • Constipation or diarrhea
  • Inflammatory joint pain (i.e. Rheumatoid Arthritis)
  • Sinusitis and post-nasal drip
  • Irritable bowel syndrome/Crohn’s disease/Ulcerative colitis
  • Asthma & recurring respiratory infections

The entire list of foods that are part of the test can be found here.  This Food Sensitivity Blood Test is suitable for both adults and children over age 1.  A blood sample is taken by finger prick at the lab (Lifelabs) and results take approximately 7-10 days after the lab receives your blood sample.  View a Sample Report


Celiac Profile ($270)

Celiac disease is a different condition from Gluten Sensitivity.   The effects of gluten sensitivity are often unpleasant (e.g. gas, bloating, diarrhea, etc.), but unlike celiac disease, it does not cause permanent damage.  In celiac disease, eating gluten triggers the immune system to attack and damage the villi (small finger-like projections of the small intestine), thereby seriously impairing the ability of the gut to absorb nutrients from food.  Celiac disease is considered an autoimmune disease and is associated with autoimmune thyroiditis, Addison’s disease, Sjorgren’s syndrome and autoimmune liver disease.

The Celiac Profile tests for gliadin antibodies to determine if gluten sensitivity is the problem as well as transglutaminase antibodies to diagnose celiac disease.  A blood sample is taken by venipuncture at the lab (Lifelabs) and results take approximately 3 weeks after the lab receives your blood sample.  View a Sample Report


Hair Cortisol ($95)

Cortisol is an adrenal hormone, often called the “stress hormone” because it regulates may of the body’s responses to stress.   Testing cortisol in the hair provides a longer-term view of stress-levels in the body than testing saliva, urine, or blood.  Just one centimeter of hair shows the average cortisol over a month.

Cortisol imbalance may be associated with abdominal weight gain, increased muscle pain, fatigue, poor exercise recovery, mild anxiety, lowered immune function, disturbed sleep, “brain fog”, lowered thyroid function, decreased muscle mass, and inflammation.

Sample collection is easy and non-invasive.  About 1 tbsp (in total) of hair from 4-5 different areas of the scalp is collected.  Results take approximately 7-10 days after the lab receives your hair sample. View a Sample Report


Candida Panel ($95)

Consuming too many sugar-rich foods or repeated antibiotic use can contribute to the overgrowth of Candida, or yeast, in the body.  Candida is often found when someone has a fungal infection of some sort, such as vaginal yeast infection, “jock itch”, or ringworm.  Other symptoms associated with Candida overgrowth include:

  • Inability to concentrate, or “brain fog”
  • Depression
  • Diarrhea
  • Fatigue
  • Menstrual cramps
  • Headaches
  • Vaginal itching or burning

A blood sample is taken by finger prick at the lab (Lifelabs) and results take approximately 7-10 days after the lab receives your blood sample.


Heavy Metal Toxicity & Micronutrient Analysis ($125)

Hair is an effective method for testing heavy metal toxicity in the body because its levels do not fluctuate like they do in blood. Toxic elements such as mercury, arsenic, aluminum, cadmium, and lead may be 200 – 300 times more concentrated in the hair than in blood or urine. This profile also tests for important nutrient levels such as magnesium, zinc, copper, chromium, and selenium. This test requires a 1 tbsp sample of hair close to the scalp obtained from a few different sections on the head. The sample can be collected in-office or at home and results take approximately 10 days after the lab receives your hair sample.   View a Sample Report


Urine Hormone Testing – Male/Female Fertility Panel ($425)

This Dried Urine Test for Comprehensive Hormones (a.k.a. DUTCH) measures hormones and hormone metabolites.  Measuring both hormones and their metabolites can give a better overall picture or your hormone production.  For example, it doesn’t just measure estrogen; it measures all the intermediate hormones in the biochemical pathways that are involved in the production of estrogen.  The DUTCH tests over 30 different hormones and their metabolites including estrogen, progesterone, testosterone, cortisol, and melatonin.  Five urine samples are collected over two days and results take approximately 3 weeks after the lab receives your sample.  View a Sample Report
