What's this test for?

This test is ideal if you're experiencing symptoms that might be related to autoimmune thyroid problems, such as unexplained fatigue, weight changes, mood swings, or temperature sensitivity. It helps identify if your immune system is attacking your thyroid gland, which happens in conditions like Hashimoto's thyroiditis and Graves's disease. Many people use this test when they have thyroid symptoms but want to understand if autoimmune activity is the underlying cause.

How should I prepare for this test?

No fasting is needed for this test, making it convenient to schedule at any time of day. You can eat and drink normally before your appointment. Simply visit your chosen lab location, and the blood draw takes just a few minutes with no special preparation required.

What's included in this test?

Thyroglobulin Antibodies

This test measures Thyroglobulin Antibodies, which are immune proteins that attack thyroglobulin, a protein made by your thyroid gland. Elevated levels indicate that your immune system may be targeting your thyroid, which is common in autoimmune thyroid diseases like Hashimoto's thyroiditis and helps explain symptoms like fatigue, weight issues, and mood changes. This marker is essential for diagnosing and monitoring autoimmune thyroid conditions and understanding if immune activity is affecting your thyroid function.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your thyroglobulin antibody levels mean and how they relate to your thyroid health. These notes include personalized recommendations like dietary changes, supplement suggestions, or whether you should follow up with an endocrinologist for further evaluation. You'll also get the standard lab report and can track your antibody levels over time using our trends feature to monitor autoimmune activity, especially helpful if you're managing a thyroid condition or making lifestyle adjustments.
Who should consider getting this test?
This test is important for anyone experiencing symptoms of thyroid dysfunction like unexplained weight changes, chronic fatigue, hair loss, or feeling unusually cold or hot. It's especially useful if you have a family history of autoimmune thyroid disease, have been diagnosed with other autoimmune conditions, or if your thyroid function tests show abnormalities but the cause is unclear. People already being treated for thyroid conditions may also use this test to monitor autoimmune activity over time.
What symptoms indicate I may need this test?
Common symptoms that suggest you might need this test include persistent fatigue that doesn't improve with rest, unexplained weight gain or difficulty losing weight, feeling cold when others are comfortable, thinning hair or hair loss, dry skin, muscle weakness, and mood changes like depression or anxiety. You might also experience brain fog, constipation, or notice swelling in your neck area. These symptoms can indicate your immune system is affecting your thyroid function.
How can I naturally support my thyroid health with autoimmune concerns?
Supporting thyroid health with autoimmune issues starts with reducing inflammation through an anti-inflammatory diet rich in vegetables, wild-caught fish, and avoiding potential triggers like gluten or excessive soy. Selenium from Brazil nuts and eggs can help reduce thyroid antibodies, while managing stress through yoga, meditation, or adequate sleep supports overall immune balance. Some people find eliminating processed foods and ensuring adequate vitamin D levels helpful, though it's important to work with a healthcare provider for personalized guidance.
What are thyroglobulin antibodies and why do they matter?
Thyroglobulin antibodies are proteins your immune system creates when it mistakenly identifies thyroglobulin, a normal thyroid protein, as a threat. When these antibodies are present, they indicate autoimmune activity against your thyroid gland, which can gradually damage the thyroid and affect its ability to produce hormones that regulate metabolism, energy, and body temperature. Detecting these antibodies early helps identify autoimmune thyroid disease before significant damage occurs and allows for proactive management.
What does high thyroglobulin antibody level mean?
Elevated thyroglobulin antibodies typically indicate that your immune system is actively attacking your thyroid gland, most commonly seen in Hashimoto's thyroiditis or Graves's disease. This autoimmune activity can gradually impair your thyroid's ability to function properly, potentially leading to hypothyroidism over time. High levels don't always mean you currently have thyroid dysfunction, but they signal increased risk and the need for monitoring your thyroid function regularly.
How often should I retest my thyroglobulin antibodies?
If you've been diagnosed with autoimmune thyroid disease, your doctor will typically recommend retesting every 6-12 months to monitor antibody levels and assess disease activity. If you're implementing lifestyle changes or treatments aimed at reducing autoimmune activity, testing every 3-6 months can help track your progress. For those with positive antibodies but normal thyroid function, annual testing along with thyroid function tests helps catch any changes early.

What this means

Your thyroglobulin antibody levels are elevated above the normal range, indicating that your immune system is producing antibodies against your thyroid gland. This suggests autoimmune thyroid activity, which is commonly seen in conditions like Hashimoto's thyroiditis, and may explain symptoms like fatigue, weight changes, or difficulty regulating body temperature.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
