Understanding Vitamin D Testing
Vitamin D is an essential nutrient that plays an important role in calcium absorption and normal bone health. It also contributes to the normal function of the immune system and other physiological processes.
Vitamin D status can be assessed by measuring 25-hydroxyvitamin D [25(OH)D], the major circulating form of vitamin D in the body. Blood levels of 25(OH)D are commonly used to evaluate an individual's vitamin D status.
Vitamin D levels may vary depending on factors such as sun exposure, dietary intake, age, lifestyle, and individual physiological conditions. Because low vitamin D status may not always produce obvious symptoms, testing can provide additional information about an individual's nutritional status.
The NOVAtest® Vitamin D Home Test uses a small finger-prick blood sample to provide an accessible way for users to obtain information about their vitamin D status at home.
