What's this test for?

This test is ideal if you're experiencing symptoms like unexplained weight changes, fatigue, hair loss, or mood swings that could point to a thyroid problem. It's also useful if you have a family history of autoimmune thyroid disease or other autoimmune conditions like type 1 diabetes. Checking for TPO antibodies helps identify whether your immune system is attacking your thyroid gland, which is a common cause of thyroid dysfunction.

What's included in this test?

This test measures thyroid peroxidase (TPO) antibodies, which are markers your immune system produces when it mistakenly targets your thyroid gland. Elevated TPO antibodies matter because they're one of the earliest signs of autoimmune thyroid conditions, often showing up before other thyroid hormone levels become abnormal. Catching this early can help you understand the root cause of thyroid symptoms rather than just treating the surface-level signs.

What happens after I get my results?

Your results will show up in your account along with an explanation of the normal range so you can see exactly where you stand. If your antibody levels are elevated, next steps usually involve tracking your thyroid function over time and making supportive lifestyle changes, such as reducing inflammatory foods and managing stress. You can download a standard lab report directly from your account for your records, and use the trends feature to monitor changes if you retest in the future. If a result looks dangerously abnormal alongside severe symptoms, seek medical care right away.

How can I naturally support thyroid health?

Eating a balanced diet with adequate iodine, selenium, and zinc can support normal thyroid function, and foods like Brazil nuts, fish, and eggs are good natural sources. Managing stress through sleep, exercise, and relaxation techniques can also help since chronic stress affects immune and hormone balance. Reducing exposure to inflammatory foods, like excess sugar and processed items, may help calm an overactive immune response. These steps support overall thyroid health but don't replace monitoring your antibody levels over time.

When will I get my results?

Results for this test are typically available within about 7 days of your sample being processed at the lab. You'll receive a notification once your results are ready to view in your account. This timeframe allows the lab to accurately measure antibody levels using specialized testing methods.

Who should consider this test?

This test is a good fit for anyone with symptoms of thyroid imbalance, such as fatigue, weight changes, hair thinning, or feeling unusually cold or hot. It's also worth considering if you have a personal or family history of autoimmune conditions like Hashimoto's, Graves' disease, or type 1 diabetes. People already diagnosed with a thyroid condition may also use this test to better understand the underlying cause.

What symptoms indicate I may need this test?

Common symptoms that suggest you might benefit from this test include persistent fatigue, unexplained weight gain or loss, hair loss, dry skin, feeling cold or overheated easily, and mood changes like anxiety or depression. Some people also notice swelling in the neck area or irregular heart rate. If these symptoms have been ongoing without a clear explanation, checking your thyroid antibodies can help identify an autoimmune cause.

What does high TPO antibody mean?

A high TPO antibody level usually means your immune system is attacking your thyroid gland, which is a hallmark of autoimmune thyroid conditions like Hashimoto's thyroiditis or Graves' disease. This doesn't always cause symptoms right away, but it can signal an increased risk of developing thyroid dysfunction over time. Simple lifestyle changes, like reducing inflammation through diet and stress management, along with regular retesting, can help you keep track of how things progress.

What causes high TPO antibodies?

High TPO antibodies are typically caused by an autoimmune response, where the immune system mistakenly identifies thyroid tissue as a threat. This can be influenced by genetics, other autoimmune conditions, chronic stress, and sometimes environmental triggers like infections. Family history plays a significant role, so if autoimmune thyroid disease runs in your family, you may be more likely to develop elevated antibodies.

How often should I retest?

If your levels are elevated or borderline, retesting every 6 to 12 months can help you track whether your antibody levels are rising, falling, or staying stable. If your results are normal but you have risk factors like family history or ongoing symptoms, an annual check can be a reasonable approach. Using the trends feature in your account makes it easy to see these changes over time.
