About This Test

Our Celiac disease genetic test will confirm whether you carry the genes associated with celiac disease and can effectively rule out the disease with an accuracy of 99%. The test is offered at $175 per person. Results for this test are ready within 1-2 weeks from the receipt of your samples at our laboratory.

Why take a genetic test?

If you suspect you have Celiac disease you may have considered the different screening and diagnostic tests available. Genetic testing for Celiac disease is a screening test that offers several advantages over other test methods:

  1. If you have a first degree relative who is celiac you are at a higher risk of developing the disease due to the fact the disease can be inherited. You have a 5-10% chance of inheriting the gene if you have a family member who has celiac disease. Only a genetic test such as ours can confirm whether you have the genes implicated in celiac disease.
  2. A common test for celiac disease is antibody blood testing. If you are celiac, this test can only be used if you are actually eating food containing gluten. A genetic test for celiac disease can be carried out at any time, at any age and irrespective of the type of diet you are on.
  3. Celiac disease genetic testing does not require a blood draw. Blood draws can be uncomfortable for some besides requiring a phlebotomist and may incur a blood draw fee. Our celiac disease test is done by means of the mouth swabs you find inside our kit. The self-sampling procedure just requires a few simple steps and precautions.

Is this a diagnostic test?

No, a celiac genetic test is not a diagnostic test. Nor are the serology tests available that measure the levels of certain antibodies in the blood which are normally produced in response to gluten. Even if results of a genetic test confirm you carry the genes which cause celiac disease, it does not mean you suffer from the illness or that you will ever develop it. However, if you do not carry the genes, you can have your mind at rest that you will not develop celiac disease.

Diagnosing celiac disease usually requires a biopsy which will establish the extent of the damage to the intestinal walls and whether the type of damage observed attributable to celiac disease.

Celiac genes

The HLA DQ2 and DQ8 are the 2 genes which we most often observe in people with celiac disease. These 2 genes are the most common although not the only potential gene involved in celiac disease. HLA stands for Human Leukocyte Antigen. HLA produces a protein which holds any foreign material (such as small foreign particles, viruses or bacteria) on the surface of the cell. In the case of individuals carrying mutations of the HLA genes, the body is unable to correctly distinguish gluten from HLA which results in an auto-immune reaction.

How serious is celiac disease?

The symptoms of celiac disease will vary depending on:

 

  • How long you have been suffering with celiac disease.
  • Your age.
  • How long you have been exposed to gluten (sometimes unknowingly through hidden gluten in foods).

There is no treatment for celiac disease – If you are celiac, you will have to follow a gluten-free diet to a T. There is no way of preventing the damage caused to the mucosa of the small intestine other than by avoiding gluten. Careful monitoring by a health care provider will be required.
