What's this test for?

This test is ideal if you're experiencing unexplained fatigue, weight changes, mood swings, or temperature sensitivity that might be related to thyroid problems. It helps identify autoimmune thyroid conditions like Hashimoto's disease or Graves disease, where your immune system mistakenly attacks your thyroid gland. Many people use this test when they have thyroid symptoms or abnormal thyroid function tests and want to understand if autoimmune issues are the underlying cause.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your thyroid antibody levels mean and how they relate to autoimmune thyroid conditions. These notes include personalized recommendations like dietary changes, supplements that may support thyroid health, or whether you should follow up with an endocrinologist. Along with your standard lab report, you can use our trends feature to track your antibody levels over time, which is especially helpful for monitoring disease progression or treatment effectiveness.

What's included in this test?

This panel measures Thyroglobulin Antibodies and Thyroid Peroxidase Antibodies. This test measures two important thyroid antibodies that indicate autoimmune thyroid disease. Thyroid Peroxidase Antibodies (TPO) help diagnose Hashimoto's thyroiditis, the most common cause of hypothyroidism, while Thyroglobulin Antibodies (TAA) provide additional confirmation of autoimmune activity. Together, these markers help distinguish autoimmune thyroid conditions from other causes of thyroid dysfunction.

Who should consider getting this test?

This test is important for anyone experiencing thyroid symptoms like fatigue, weight changes, or mood issues, especially if routine thyroid tests show abnormal results. It's also recommended for people with a family history of autoimmune thyroid disease, women who are pregnant or planning pregnancy, and anyone diagnosed with other autoimmune conditions who may be at higher risk for thyroid problems.

What symptoms indicate I may need this test?

Common symptoms include persistent fatigue, unexplained weight gain or difficulty losing weight, feeling unusually cold or sensitive to temperature, hair thinning or loss, dry skin, and mood changes like depression or anxiety. You might also experience muscle weakness, joint pain, irregular menstrual periods, brain fog, or an enlarged thyroid gland (goiter). If you have these symptoms along with abnormal TSH or thyroid hormone levels, this test can help identify if autoimmune disease is the cause.

How can I naturally support my thyroid health with autoimmune thyroid disease?

Managing autoimmune thyroid conditions often involves reducing inflammation through diet, such as limiting gluten and processed foods while focusing on anti-inflammatory foods like fatty fish, leafy greens, and berries. Ensuring adequate selenium intake through Brazil nuts, eggs, and seafood may help reduce thyroid antibody levels. Managing stress through yoga, meditation, or gentle exercise, getting 7-8 hours of quality sleep, and avoiding environmental toxins can also support thyroid function and reduce autoimmune activity.

What are thyroid antibodies and why do they matter?

Thyroid antibodies are proteins your immune system creates when it mistakenly identifies your thyroid tissue as a threat. When present in high levels, these antibodies attack and damage the thyroid gland, leading to conditions like Hashimoto's disease (causing hypothyroidism) or Graves disease (causing hyperthyroidism). Detecting these antibodies helps explain why your thyroid isn't functioning properly and guides appropriate treatment and monitoring strategies.

What does it mean if my thyroid antibodies are high?

High thyroid antibody levels indicate that your immune system is actively attacking your thyroid gland, which is a hallmark of autoimmune thyroid disease. Elevated TPO antibodies are most commonly associated with Hashimoto's thyroiditis, while elevated thyroglobulin antibodies provide additional confirmation of autoimmune activity. High antibodies often mean you'll need closer monitoring of your thyroid function and may eventually require thyroid hormone replacement therapy.

What causes thyroid antibodies to develop?

Thyroid antibodies develop due to a combination of genetic predisposition and environmental triggers that cause your immune system to malfunction. Factors that may trigger or worsen autoimmune thyroid disease include chronic stress, viral infections, hormonal changes (especially during pregnancy or menopause), nutrient deficiencies like selenium or vitamin D, excessive iodine intake, and environmental toxins. Having other autoimmune conditions or a family history also increases your risk.

How often should I retest my thyroid antibodies?

If you're newly diagnosed with autoimmune thyroid disease, your doctor may retest antibodies every 6-12 months to monitor disease progression and adjust treatment as needed. Once your condition is stable and you're on appropriate treatment, annual testing is typically sufficient. However, if you experience new or worsening symptoms, more frequent testing may be needed to assess disease activity and ensure your thyroid hormone levels remain balanced.
