Vitamin D



This test measures your levels of vitamin D, a key nutrient for bone strength and overall health. Your body produces vitamin D after exposure to sunlight or from consuming certain foods and supplements. Because it enables your body to absorb calcium, vitamin D is essential for healthy bones. Not getting enough vitamin D can increase your risk of weak bones (osteoporosis), bone fractures, muscle weakness, and high blood pressure.

This test does not require fasting.
