You can order a GlutenID® test kit online through our SHOP.
No, a blood sample is not necessary for GlutenID® testing. Instead, cheek cells collected from inside your mouth are used to obtain a DNA sample.
Yes. GlutenID® uses a simple cheek swab to gently collect cells from inside the mouth. Samples can be collected from any age group.
Our kits contain a packaged swab and instructions for how to collect the cheek cells from inside both sides of your mouth.
No. The GlutenID® tests DNA, so it is accurate if you are on a gluten-free or a gluten-containing diet.
No. The GlutenID® tests DNA which is unaffected by what you have eaten before the test. The only thing not to do is eat at the same time you are swabbing the inside of your mouth as food could interfere with sample collection.
Any time of day or night is fine for collecting cheek cell samples.
It is preferable to send samples to the laboratory as soon as they are collected.
No, the swab sample is stable at room temperature for several weeks without affecting DNA collection.
A prepaid USPS mailing label is included in every kit. Simply place your swab tubes into the labeled transport sleeve, place in the GlutenID® kit, and put them in a United States Postal Service Collection Box.
NOTE: FedEx and UPS will not deliver USPS samples so do not drop off your kit with either of these carriers.
Yes. Mail your kit to the lab as normal and provide name and date of birth for the person from who the sample was collected. We will match this information with the GID number when the sample arrives at the lab.
You will receive a confirmation email when your sample is received by the lab. We report results within 14 business days after the sample arrives at the laboratory.
PacificDx, a College of American Pathologists (CAP) accredited laboratory in Irvine, CA is the only laboratory certified to run the GlutenID® test.
Results are sent via encrypted email to you and/or your doctor via the email address you provided when registering your kit.
Approximately 1% of samples do not yield DNA of sufficient quality/quantity for testing. In these cases a new kit is provided free of charge. If a second sample fails, you will receive a refund.
Positive results for specific genetic variants are reported within a gradient of Low Elevated Disease Risk for the following specific variant/disease pairs:
Having DQ2 and/or DQ8 genes is not diagnostic of celiac disease. However, these findings indicate your immune system has the capability to recognize gluten proteins and mount an abnormal immune response against your own tissue.
If a symptomatic individual on a gluten containing diet tests positive for celiac-associated genes, the best confirmatory test is tissue transglutanimase (tTG) antibody testing. However, this test will only be positive if adequate gluten has been consumed prior to testing. If your doctor wants you to have your blood tested for tTG antibodies do not go on a gluten-free diet until after your antibodies are tested.
Your doctor will order tissue transglutanimase (tTG) testing to confirm your diagnosis.
NEGATIVE results mean you have not inherited the celiac-associated genes DQ2 or DQ8 and you have < 1% chance of developing celiac disease.
You may be suffering from a gluten allergy or non-celiac gluten sensitivity. However, GlutenID® does not test for either of these conditions.

A celiac GHR test describes if a person has genetic variants associated with an elevated risk of developing celiac disease. A GHR test does not describe a person’s overall risk for developing celiac disease or predict if an individual will develop the disease in the future.
No. Once the DNA has been sequenced and results reported, samples are de-identified and discarded by the laboratory.
