What's this test for?

This test is ideal if you're experiencing symptoms like muscle cramps, tingling in your fingers or around your mouth, unexplained fatigue, or brittle bones that might point to a parathyroid problem. It helps if you have a personal or family history of autoimmune conditions and your calcium levels have come back unusual. The test looks for antibodies that attack the parathyroid gland, which can lead to low parathyroid hormone (hypoparathyroidism) and calcium imbalances.

What's included in this test?

This test measures antibodies your immune system may be producing against the parathyroid gland. These antibodies matter because when they attack parathyroid tissue, they can reduce the gland's ability to make parathyroid hormone, which your body needs to regulate calcium and phosphorus levels properly.

What happens after I get my results?

Your results will be available in your account, with each value's normal range clearly explained so you know exactly where you stand. If your antibody levels are elevated, next steps typically include tracking your calcium levels closely and making dietary adjustments to support bone and muscle health, while very low calcium or severe symptoms like muscle spasms call for seeking medical care right away. You can download the standard lab report directly from your account at any time. The trends feature also lets you track this biomarker over time if you retest in the future.

How can I naturally support parathyroid and calcium health?

Eating calcium-rich foods like leafy greens, dairy, or fortified alternatives can help support healthy calcium levels. Getting enough vitamin D through sunlight, food, or a supplement helps your body absorb calcium more effectively. Reducing stress and avoiding excessive alcohol or caffeine can also support overall hormone balance, but if you have confirmed antibodies or ongoing symptoms, monitoring your levels regularly is important.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once ready, they'll be uploaded directly to your secure online account, and you'll be notified so you can log in and review them right away.

Who should consider this test?

Anyone with symptoms of low calcium, such as muscle cramps, tingling, or fatigue, especially alongside a family history of autoimmune disease, should consider this test. It's also useful for people who've had unexplained abnormal calcium results on previous bloodwork and want to understand the underlying cause.

What symptoms indicate I may need this test?

Common signs include muscle cramps or spasms, numbness or tingling around the mouth, fingers, or toes, unusual fatigue, and brittle or weak bones. Some people also notice mood changes or difficulty concentrating. If these symptoms appear together, especially with a known autoimmune condition, this test can help identify the cause.

What does a high antibody result mean?

A high result means your immune system is producing antibodies that target your parathyroid gland, which can interfere with normal hormone production. This is often linked to autoimmune hypoparathyroidism, which can cause your calcium levels to drop over time. Tracking your calcium alongside this result and adjusting your diet can help manage the impact.

How often should I retest?

If your first result comes back positive or borderline, retesting every few months can help you track whether antibody levels are rising, stable, or falling. Once levels stabilize and your calcium stays in a healthy range, retesting once or twice a year is usually enough. Retesting sooner is a good idea if new symptoms appear.

What should I do if my results are abnormal?

Start by reviewing the explanation provided with your report so you understand what the specific number means for you. Focus on calcium and vitamin D intake through diet, and keep a symptom log to notice any changes like cramping or numbness. If you experience severe symptoms like muscle spasms or seizures, seek medical care immediately.
