Getting ready to take a celiac blood test? Read our guide for helpful tips and tricks to prepare for the test and ensure an accurate diagnosis.


When it comes to managing celiac disease, a blood test is one of the fastest and most effective ways to get an accurate diagnosis. But with so many different elements to consider before taking your celiac blood test, it's important to take some time and properly prepare in order to ensure your results give an accurate representation of any underlying health issues you may have. In this post, we'll review tips for preparing for a celiac blood test that will help make sure your results are as accurate and reliable as possible.

Understand Celiac Disease and the Importance of Testing

Before diving into the preparations for a celiac blood test, it's important to understand what celiac disease is and why testing is crucial. Celiac disease is an autoimmune disorder. It triggers the body to attack the small intestine upon consumption of gluten, a protein found in grains such as wheat, barley, and rye. This can lead to serious health complications, if left untreated. A celiac blood test detects antibodies in your blood that signal whether your body has responded to gluten in a way that suggests celiac disease.

Maintain a Gluten-Containing Diet Before the Test

Our next tip for preparing for a celiac blood test is the most important one. To avoid false-negative test results, it is essential to continue consuming gluten in your diet leading up to the test. Some people may inadvertently alter their diets if they suspect they have celiac disease, leading to insufficient gluten intake for an accurate test. To ensure the accuracy of the results, you should consume a gluten-containing diet for between six and eight weeks leading up to the test.

Know the Types of Blood Tests Available

There are several types of celiac blood tests, including Tissue Transglutaminase Antibodies (tTG-IgA), Deamidated Gliadin Peptide Antibodies (DGP-IgA and DGP-IgG), and Endomysial Antibodies (EMA-IgA). Each test has its advantages, and your healthcare provider will determine the best test for your specific situation. Knowing the type of test you will be taking can help you better understand and prepare for the process.

Consider At-Home Test Kits

At-home testing options, such as RxHomeTest's celiac disease antibody test, offer a convenient way to get tested without visiting a healthcare facility. These tests are designed to be user-friendly and typically involve a simple finger-prick blood sample. They come with easy-to-follow instructions and often provide quick, accurate results that you can share with your healthcare provider. And our test kit checks most of the key markers to ensure you get the most comprehensive diagnosis. You can even order a genetic test, if you prefer.

Preparing for a celiac blood test involves understanding the disease, maintaining a gluten-containing diet, being knowledgeable about the test types, and considering at-home options. By following these strategies, you can ensure accurate results and a better understanding of your health. Remember to always consult with a healthcare provider for personalized advice and recommendations based on your specific situation.
