What's this test for?

This test is ideal if you're experiencing bone pain, kidney stones, fatigue, muscle weakness, or unexplained mood changes that could be linked to calcium or parathyroid problems. It helps figure out why your calcium levels might be too high or too low, and whether your parathyroid glands are working correctly. It's also useful if a previous blood test showed abnormal calcium and you need to understand the underlying cause.

What's included in this test?

This test measures parathyroid hormone (PTH) alongside ionized calcium, giving a fuller picture than checking calcium alone. PTH controls how your body manages calcium in the blood, bones, and kidneys, so looking at both together helps pinpoint whether a calcium imbalance is coming from the parathyroid glands themselves or from another cause like cancer or kidney issues. Testing them side by side gives much clearer answers than either result on its own.

What happens after I get my results?

Your results will show up in your account with each value's normal range clearly explained, so you can see exactly where you stand. Depending on what the numbers show, next steps might include simple diet changes, adjusting supplements, or retesting in a few weeks to confirm a pattern. If a value comes back dangerously high or low, the report will flag it so you know to seek care right away. You can download a standard lab report anytime, and the trends feature lets you track your PTH and calcium levels over time.

How can I naturally support healthy calcium and parathyroid balance?

Getting enough vitamin D through sunlight, food, or a supplement helps your body regulate calcium properly. Eating calcium-rich foods like dairy, leafy greens, and fortified foods in moderation supports steady levels without overloading your system. Staying hydrated helps prevent kidney stones, which are linked to calcium imbalances, and limiting excess caffeine or sodium can also help keep calcium levels steady.

When will I get my results?

Results are typically ready within about 7 days of your blood draw. You'll get a notification once they're posted to your account, where you can view the detailed breakdown and download the full report.

Who should consider this test?

Anyone with symptoms of high or low calcium, such as bone pain, kidney stones, muscle cramps, fatigue, or confusion, should consider this test. It's also a good option for people who've had abnormal calcium results before and want a clearer picture of the cause. People with a family history of parathyroid or bone conditions may also want to check their levels.

What symptoms indicate I may need this test?

Common symptoms include bone or joint pain, frequent kidney stones, unusual fatigue, muscle weakness, nausea, constipation, or brain fog. Some people also notice increased thirst and frequent urination when calcium levels are off. If you're dealing with a combination of these symptoms, checking PTH and calcium together can help explain what's going on.

What does high PTH mean?

High PTH often means your parathyroid glands are overactive, a condition called hyperparathyroidism, which can cause your body to pull too much calcium from your bones. This can lead to weak bones, kidney stones, or high calcium in the blood over time. Simple next steps include increasing hydration, watching your calcium and vitamin D intake, and retesting to see if the pattern continues.

What does low PTH mean?

Low PTH can mean your parathyroid glands aren't producing enough hormone, which may cause calcium levels to drop too low. This can lead to symptoms like muscle cramps, tingling in the hands or feet, or fatigue. If your levels are low, retesting and tracking symptoms closely is a good next step, and eating calcium-rich foods may help in the meantime.

How often should I retest?

If your first results are abnormal, retesting in 4 to 8 weeks can help confirm whether the pattern is consistent or was a one-time fluctuation. If you're being monitored for an ongoing calcium or parathyroid issue, retesting every few months can help you track progress. Using the trends feature in your account makes it easy to compare results side by side over time.
