VITAMIN D3
What does VITAMIN D3 measure?
This test measures vitamin D3 levels in the body, which are important for calcium absorption, bone health, and normal muscle and immune function. It may be used to assess vitamin D status, investigate possible deficiency or excess, or monitor levels during supplementation when clinically indicated. Results are interpreted alongside medical history, diet, sun exposure, and other relevant laboratory findings.
