What's this test for?

This test is ideal if you're concerned about bone health, have a family history of osteoporosis, or are experiencing unexplained bone pain or frequent fractures. It measures how quickly your bones are breaking down, helping identify early signs of bone loss before serious complications develop. Many people use this test when they're at risk for osteoporosis due to age, menopause, medication use, or want to monitor the effectiveness of bone-strengthening treatments.

How should I prepare for this test?

Fasting: 12 hours
No biotin: 72 hours

You'll need to fast for at least 12 hours before your test, meaning no food or beverages except water. Schedule your blood draw for early morning between 8-10 am, as bone markers naturally fluctuate throughout the day and are elevated at night. If you take high-dose biotin supplements (vitamin B7 or B8), stop taking them at least 72 hours before your test, as they can interfere with results.

What's included in this test?

C Telopeptide (Ctx)

This test measures C-Telopeptide (CTx), a biomarker that indicates how rapidly your bones are breaking down. CTx levels reveal the rate of bone resorption, which is crucial for assessing your risk for osteoporosis and predicting fracture risk. This measurement helps determine if you need intervention to slow bone loss and is also valuable for monitoring whether osteoporosis treatments are working effectively.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your bone resorption rate means for your bone health and fracture risk. These notes include personalized recommendations like dietary changes, calcium and vitamin D supplementation, weight-bearing exercise suggestions, or whether you should consider bone-strengthening medications. You'll also get the standard lab report and can track your bone health markers over time using our trends feature to see if your interventions are slowing bone loss.
Who should consider getting this test?
This test is important for postmenopausal women, men over 50, and anyone with risk factors for osteoporosis like family history, previous fractures, or long-term steroid use. It's also valuable for people already being treated for bone loss who need to monitor treatment effectiveness. If you have conditions like rheumatoid arthritis, hyperthyroidism, or take medications that affect bone density, this test provides important insights.
What symptoms indicate I may need this test?
Consider this test if you've experienced unexplained bone pain, loss of height over time, or fractures from minor falls or injuries. Other signs include a stooped posture, back pain from compressed vertebrae, or being in a high-risk group like postmenopausal women or people taking long-term corticosteroids. Early bone loss often has no symptoms, so testing is important if you have risk factors even without obvious signs.
How can I naturally support my bone health?
Supporting bone health starts with ensuring adequate calcium (1,000-1,200 mg daily) through dairy, leafy greens, and fortified foods, plus vitamin D through sunlight and supplements. Regular weight-bearing exercises like walking, jogging, or strength training help maintain bone density. Limiting alcohol, avoiding smoking, and reducing excessive caffeine intake can also protect your bones from accelerated breakdown.
What is C-Telopeptide and why does it matter?
C-Telopeptide (CTx) is a fragment released into your bloodstream when bone tissue breaks down. Your bones are constantly remodeling, breaking down old bone and building new bone, but if breakdown happens too quickly, you lose bone density over time. Measuring CTx helps identify if this breakdown is happening faster than it should, which increases your risk for osteoporosis and fractures.
What does high C-Telopeptide mean?
High CTx levels indicate that your bones are breaking down faster than normal, suggesting increased bone resorption. This can mean you're at higher risk for developing osteoporosis or that existing bone loss is progressing. Elevated levels are common during menopause, with certain medications like corticosteroids, or in conditions like hyperthyroidism that accelerate bone turnover.
How often should I retest my bone markers?
If you're starting treatment for bone loss, your doctor typically recommends retesting every 3-6 months to ensure the therapy is working effectively. Once your levels stabilize and treatment is established, testing every 6-12 months helps monitor long-term progress. If you're testing for initial assessment and results are normal, retesting annually or every few years may be sufficient unless risk factors change.

What this means

Your C-Telopeptide level is elevated, indicating that your bones are breaking down faster than optimal. This suggests increased bone resorption, which may put you at higher risk for developing osteoporosis or experiencing bone loss over time. This is common during menopause or with certain medications, but it's important to address.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
