Vitamin D plays an important role in several biological processes including bone health, immune function and muscle performance.
A vitamin D blood test measures the level of vitamin D circulating in the bloodstream. Healthcare professionals sometimes use this test to assess vitamin D status or monitor levels over time.
Many individuals living in Edinburgh, Livingston and across West Lothian choose to monitor vitamin D levels, particularly during winter months when sunlight exposure may be limited.
What a Vitamin D Blood Test Measures
The most common vitamin D test measures a form of vitamin D known as 25-hydroxyvitamin D.
This marker reflects vitamin D stores within the body and is commonly used to evaluate vitamin D status.
Laboratory results are interpreted using reference ranges.
