Are you confused about whether you can have Hashimoto’s even if your antibodies come back negative? Well, Dr. Martin Rutherford from Power Health Reno is here to answer that question for you. In his video, he explains that it is not automatic to rule out Hashimoto’s just because your antibody results are negative. He discusses the evolution of understanding autoimmunity, emphasizing that Hashimoto’s is now recognized as the cause of 85 to 94.5% of all hypothyroidism cases. Dr. Rutherford also highlights the importance of considering symptoms and individual ranges when diagnosing Hashimoto’s, as lab test results can vary. So if you’re curious about the connection between Hashimoto’s and negative antibodies, this video provides valuable insights and advice.

Dr. Rutherford understands the frustration of having a condition like hypothyroidism and wanting to find the root cause. He encounters many patients experiencing the same dilemma, and he offers complimentary consultations to address their concerns. With his extensive experience in functional medicine, Dr. Rutherford explains the intricacies of Hashimoto’s and the importance of an individualized approach. So if you have ever questioned the link between negative antibodies and Hashimoto’s, this video will provide you with valuable information to help you better understand your condition and seek the appropriate medical advice.

Can You Have Hashimoto’s Even with Negative Antibodies?

Hashimoto’s and Negative Antibodies

Hashimoto’s disease is an autoimmune condition that affects the thyroid gland, leading to an underactive thyroid or hypothyroidism. Typically, the diagnosis of Hashimoto’s is confirmed through the presence of specific antibodies, such as thyroid peroxidase (TPO) antibodies or thyroglobulin antibodies. However, there are cases where individuals with Hashimoto’s may have negative antibody results. This raises the question: Can you have Hashimoto’s even with negative antibodies?

Understanding Autoimmunity and Hashimoto’s

To understand why someone can have Hashimoto’s despite negative antibody results, it’s important to grasp the nature of autoimmunity. Autoimmunity occurs when the immune system mistakenly attacks healthy cells and tissues in the body. In the case of Hashimoto’s, the immune system targets the thyroid gland, leading to inflammation and damage.

In some cases, the antibodies may not be detectable in blood tests due to variations in individual immune responses or specific stages of the disease. It’s also possible for antibody levels to fluctuate over time, making it difficult to capture their presence accurately in a single test.

Importance of Symptom Assessment

While antibody tests play a crucial role in diagnosing Hashimoto’s, they are not the sole determining factor. Evaluating the symptoms experienced by the individual is equally important. Hashimoto’s is often associated with a wide range of symptoms, including fatigue, weight gain, hair loss, depression, and brain fog.

If a person presents with the typical symptoms of Hashimoto’s, it’s crucial to consider the possibility of the condition, even if the antibody tests come back negative. The symptoms, along with a comprehensive assessment, can provide valuable insights into the presence of Hashimoto’s.

Variations in Antibody Ranges

The interpretation of antibody test results can also be impacted by the variations in reference ranges used by different medical institutions. The reference range refers to the range of values considered normal for a particular test. These ranges can vary from one laboratory to another, leading to inconsistent interpretations of the test results.

For instance, the Mayo Clinic’s reference range for TPO antibodies is 0 to 9, while other hospitals may use ranges such as 0 to 24 or even 0 to 32. This discrepancy can lead to conflicting outcomes, with individuals receiving different diagnoses based on where their tests were conducted.

The Fluctuating Nature of Antibody Testing

Antibody levels in the blood can fluctuate due to various factors. Certain triggers, such as gluten consumption for individuals with gluten sensitivity, can cause antibody levels to surge temporarily. On the other hand, strict adherence to a gluten-free diet may result in lower or undetectable antibody levels.

This fluctuation in antibody levels highlights the importance of considering the timing of the antibody tests. A negative result obtained during a period of low antibody activity does not necessarily rule out the presence of Hashimoto’s, especially if the individual shows other clinical signs of the condition.

The Role of Gluten and Other Triggers

Although not everyone with Hashimoto’s has a gluten sensitivity, research has shown a significant association between the two. Gluten is a protein commonly found in wheat, barley, and rye. Consumption of gluten can trigger an autoimmune response in individuals with celiac disease, an autoimmune condition that affects the gut.

Even in individuals without celiac disease, gluten can potentially worsen autoimmune thyroid conditions like Hashimoto’s. Eliminating gluten from the diet has been found to reduce inflammation and improve symptoms in some individuals. Thus, it may be worth considering a gluten-free diet, alongside other dietary and lifestyle modifications, to manage Hashimoto’s symptoms and promote overall health.

The Inaccuracy of a Single Antibody Test

Relying solely on the results of a single antibody test to diagnose or rule out Hashimoto’s can be misleading. As mentioned earlier, antibody levels can fluctuate, and the accuracy of a single test may be compromised. Taking a comprehensive approach that includes evaluating symptoms, medical history, and multiple antibody tests over time can provide a more accurate diagnosis.

In some cases, other diagnostic methods, such as ultrasound or a fine-needle biopsy, may be necessary to confirm the presence of Hashimoto’s. These additional tests can provide visual evidence of thyroid inflammation and help determine the appropriate course of treatment.

Importance of Repeated Testing

Given the potential variations and limitations of antibody testing, it is essential to conduct repeated tests to ensure an accurate diagnosis. Repeating the tests at different intervals can help capture fluctuations in antibody levels and provide a more comprehensive understanding of the individual’s immune response.

It is not uncommon for individuals initially diagnosed with negative antibodies to later test positive. This highlights the dynamic and evolving nature of autoimmune diseases like Hashimoto’s.

The Link Between Positive Antibodies and Hashimoto’s

While negative antibody results can occur in individuals with Hashimoto’s, it’s important to note that positive antibody results are strongly indicative of the condition. The presence of specific antibodies, such as TPO antibodies or thyroglobulin antibodies, confirms the autoimmune nature of the disease.

However, it’s worth noting that the absence of these antibodies does not definitively rule out Hashimoto’s. Other factors, such as individual immune responses and timing of the tests, can influence the results.


In conclusion, it is possible to have Hashimoto’s even with negative antibodies. The diagnosis of Hashimoto’s should not rely solely on antibody test results but should also consider the individual’s symptoms, medical history, and a comprehensive evaluation. Repeated testing over time may be necessary to capture fluctuations in antibody levels and ensure an accurate diagnosis.

If you suspect that you may have Hashimoto’s despite negative antibody results, it’s crucial to consult with a healthcare professional who specializes in thyroid disorders and autoimmune conditions. They can guide you through the diagnostic process, help manage your symptoms, and develop an appropriate treatment plan tailored to your specific needs. Remember, early detection and proper management can significantly improve the quality of life for individuals with Hashimoto’s.
