Bone health blood test Plymouth
A bone health blood test Plymouth is essential if you’re experiencing bone pain, have a family history of osteoporosis, or want to understand your current bone strength. At Tamar Health, our bone health blood test measures vitamin D, calcium, phosphate, alkaline phosphatase, and parathyroid hormone — giving you a complete picture of your bone metabolism and mineral status.
Why bone health testing matters
Vitamin D deficiency is extremely common in the UK, particularly during winter months when sunlight exposure is limited. Without adequate vitamin D and calcium, your bones become weaker, increasing the risk of fractures and conditions like osteoporosis. This is especially important for women over 50, older adults, and anyone with limited sun exposure. Our bone health blood test helps identify deficiencies early, when they’re easiest to treat through supplementation or dietary changes.
What this test measures
Your bone health blood test includes five key markers that work together to assess your skeleton’s health and mineral balance. Each one tells part of the story about your bone strength and calcium regulation.
| Marker | What it measures | Why it matters |
|---|---|---|
| Vitamin D (25-OH) | Circulating vitamin D levels in your blood | Vitamin D is essential for calcium absorption and bone mineralisation. Deficiency causes weak bones and poor muscle function |
| Calcium | Total calcium in your blood | Maintains bone density and is vital for muscle contraction and nerve function |
| Phosphate | Phosphate levels in your blood | Works with calcium to form and maintain bone structure |
| Alkaline phosphatase (ALP) | Enzyme activity related to bone turnover | Elevated levels may indicate bone remodelling or liver issues; low levels can suggest malnutrition |
| PTH (parathyroid hormone) | Hormone regulating calcium and phosphate | High PTH may indicate low vitamin D or calcium; helps diagnose hyperparathyroidism |
Who should get this test?
A bone health blood test is recommended if you have symptoms suggesting bone or mineral deficiency, risk factors for osteoporosis, or simply want to establish a baseline of your bone health. Common reasons for testing include bone or joint pain, a history of fractures, muscle weakness, fatigue, or concerns about your long-term bone strength. Post-menopausal women, older adults, people with limited sun exposure, and those with darker skin tones (who absorb less vitamin D from sunlight) are particularly at risk of deficiency.

What your results mean
Understanding your results
Your bone health blood test results will show whether your vitamin D, calcium, and other markers are in the healthy range. Vitamin D levels below 50 nmol/L are considered deficient in the UK; levels between 50–74 nmol/L may be insufficient depending on clinical context. Calcium levels outside the normal range can indicate parathyroid disease or kidney problems. Phosphate and alkaline phosphatase help us understand whether your bones are mineralising properly.
Elevated PTH often accompanies low vitamin D, as your parathyroid glands work harder to maintain calcium levels. If your results show deficiency, supplementation with vitamin D3 and ensuring adequate dietary calcium intake can make a significant difference within weeks to months. Our clinicians will review your results and discuss the best approach for your situation.
What happens at your appointment
When you arrive for your bone health blood test at Tamar Health in Estover, a trained phlebotomist will take a small blood sample, typically from a vein in your arm. The process is quick — usually under five minutes — and requires no special preparation. You do not need to fast for this test, so you can eat and drink normally beforehand.
Your blood sample is processed in our laboratory, and results are typically available within 24–72 hours. We’ll contact you with your results and can arrange a follow-up consultation to discuss findings and any recommended next steps, such as supplementation or dietary changes. If your results reveal concerning findings, we can advise you on whether GP referral or specialist opinion is needed.
Frequently asked questions
Do I need to fast before a bone health blood test?
No, fasting is not required for this test. You can eat and drink normally before your appointment. However, ensure you’re well hydrated as this makes blood sampling easier.
What should I do if my vitamin D is low?
If your results show vitamin D deficiency, supplementation with vitamin D3 (cholecalciferol) is usually recommended. Doses vary based on severity; many people benefit from a daily dose of 1000–2000 IU. Spending time in sunlight and eating vitamin D-rich foods like fatty fish, egg yolks, and fortified milk can also help. Our clinician will recommend a personalised plan based on your results.
When should I have this test done?
If you have symptoms of bone weakness, muscle pain, or fatigue, or if you’re over 50, a bone health test is a good preventive measure. Winter is an especially good time to test for vitamin D, as deficiency is most common during months with lower sunlight. Those with a family history of osteoporosis should consider testing earlier.
Will my GP accept results from a private bone health blood test?
Yes, GPs routinely accept private blood test results. You can share your results with your GP, who may use them to guide further management or prescribe treatment if needed. Tamar Health results are recognisable to all UK healthcare providers.
What if my PTH is high but my calcium is normal?
This can occur in early hyperparathyroidism or with vitamin D deficiency. High PTH typically indicates your parathyroid glands are working hard to maintain calcium, often because vitamin D or calcium intake is low. Further investigation may be needed, and your Tamar Health clinician will advise whether GP referral for specialist assessment is appropriate.
