Vitamin D helps control calcium and phosphate in the body, keeping bones, teeth and muscles healthy. A lack of vitamin D in the UK can cause many symptoms such as tiredness, depression and aches and pains.
- Weakness in muscles
- Pain in bones
- Deformities in joints (very rare)
- Rickets (which presents in children as abnormal growth patterns)
When to test
The test can be used to identify Vitamin D deficiency in those with symptoms, and to monitor treatment in those who are taking supplements. Once identified, Vitamin D deficiency can be effectively treated using simple tablets. You will need follow up blood tests to ensure that the treatment is effective.
When to test:
- If you are experiencing symptoms of vitamin D deficiency (fatigue, bone pain, muscle weakness, muscle aches, muscle cramps and depression)
- If you are at risk of vitamin D deficiency, e.g. you spend a lot of time indoors, you don’t get much sun exposure or you are from the Indian Subcontinent or Sub-Saharan Africa
- If you have received treatment for low vitamin D and would like to monitor your response to treatment
- If you haven’t received treatment for low vitamin D levels but have been told that they were previously low and would like to measure your current levels
25-hydroxyvitamin D (supply)
One of the Vitamin D biomarkers that has shown the most utility to date is the plasma concentration of 25-hydroxyvitamin D.
Parathyroid hormone (function)
The plasma concentration of parathyroid hormone is another key Vitamin D biomarker.
The presence or absence of rickets — which can be caused by Vitamin D deficiency in severe cases — is a final biomarker.
