Overview of the Vitamin D Blood Test

What the Vitamin D Test Screens For

The Vitamin D Test identifies deficiency. Vitamin D deficiency is common in the UK and can contribute to bone pain, muscle weakness, and fatigue. It is particularly relevant for individuals with limited sun exposure, strict dietary plans, or bone health concerns.

Our Cardiff private GP service offers convenient, discreet blood testing as part of a broader Blood Tests pathway. If you are considering more than one blood test, you can reference our Blood tests in Cardiff page for details on the range of tests available.

What to expect: A simple blood sample is collected by a trained clinician, usually from a vein in the arm. Results are interpreted by our GPs, who will discuss what they mean for your health and any follow-up steps.

How NHS Guidance Aligns with Private Testing

Our NHS-guideline aware approach combines private testing with personalised care. The NHS UK advises on vitamin D supplementation and monitoring if levels are low or you have risk factors. You can read more at the NHS vitamin D guidance.

This test checks for deficiency that may cause fatigue or low mood. A GP can advise on supplements or treatment if levels are low. In Cardiff, our private GP team provides confidential assessment, test results interpretation, and ongoing management if required.
