What's this test for?

This test is ideal if you're experiencing bone pain, muscle weakness, kidney stones, or unexplained fatigue that could be linked to a calcium imbalance. It's also useful if a recent blood test showed abnormal calcium levels and you want to understand what's driving it. Parathyroid hormone (PTH) problems can cause a wide range of symptoms that are easy to mistake for other conditions.

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. Depending on your PTH level, next steps might include adjusting your calcium or vitamin D intake, staying hydrated, or retesting in a few months to see if levels have changed. If your result is significantly outside the normal range, it's a good idea to seek medical care promptly. You can download a standard lab report anytime and track your PTH levels over time using the trends feature.

Who should consider this test?

People with a history of kidney stones, brittle bones, muscle cramps, or fatigue that hasn't been explained by other causes should consider this test. It's also useful for anyone who has had abnormal calcium results in a previous blood test. Those with a family history of parathyroid or bone-related conditions may also benefit from checking their levels.

What symptoms indicate I may need this test?

Common signs include bone pain, frequent kidney stones, muscle weakness or cramps, fatigue, and digestive issues like nausea or constipation. Some people also notice increased thirst and urination, or trouble concentrating. If several of these symptoms show up together, it may point to a calcium or parathyroid hormone imbalance worth checking.

How can I naturally support healthy calcium and bone balance?

Getting enough vitamin D through safe sun exposure or food sources like fatty fish and fortified milk can help your body regulate calcium properly. Weight-bearing exercise, such as walking or light strength training, supports bone health and calcium metabolism. Staying well hydrated and limiting excess sodium can also help reduce strain on your kidneys, which play a role in calcium balance.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once processed, they'll be uploaded directly to your secure online account, and you'll be notified as soon as they're available.

What does high PTH mean?

A high PTH level often means your parathyroid glands are producing too much hormone, which can pull calcium out of your bones and raise blood calcium levels over time. This can be linked to issues like vitamin D deficiency, kidney problems, or an overactive parathyroid gland. Simple lifestyle steps like improving vitamin D intake can help, but a markedly high result should be followed up with retesting soon.

What does low PTH mean?

A low PTH level can mean your parathyroid glands aren't producing enough hormone, which may lead to low calcium levels in your blood. This can sometimes cause muscle cramps, tingling in the fingers, or fatigue. Making sure you're getting enough calcium and vitamin D in your diet is a good first step, and retesting can help confirm whether the pattern continues.

What causes abnormal PTH levels?

Abnormal PTH can be caused by vitamin D deficiency, kidney disease, certain medications, or growths on the parathyroid glands themselves. Diet, hydration, and overall kidney health all play a role in keeping calcium and PTH balanced. Identifying the underlying cause usually starts with looking at your calcium, vitamin D, and kidney function together.

How often should I retest?

If your first result is borderline or newly abnormal, retesting in 2-3 months is a reasonable starting point to see if lifestyle changes are helping. If levels are significantly out of range, more frequent monitoring may be worthwhile. Using the trends feature in your account makes it easy to track changes over time.
