Collect a sample of blood from your fingertip, dilute in the buffer solution and drop the test strip in the buffer solution mix.
If the result is positive: The test indicates that there is Coeliac disease associated IgA antibodies in the tested blood. Detection of these antibodies indicates a high probability of an existing Coeliac disease. For the final diagnosis and possible treatment, contact your doctor for advice. Do not start a gluten-free diet without consulting your doctor first.
If the test result is negative: The test indicates that there is no coeliac disease associated IgA antibodies in the tested blood. An existing coeliac disease can virtually be ruled out. If gastrointestinal complaints are present, further medical investigation is necessary. Also, if you have been following a gluten-free diet, the level of IgA autoantibodies will decrease and may become undetectable a few weeks after the change in diet, or at least in the six months thereafter. Therefore you can have a negative result if you are following the gluten-free diet. This is also a way to monitor the effects of the gluten-free diet. In addition, in the case of a few rare medical cases, such as IgA deficiency, the test may render a false negative result. If the test is contrary to your expectations, consult your doctor.
