The Vitamin D Plus Test provides a comprehensive assessment of your Vitamin D status by measuring total Vitamin D levels (25-hydroxyvitamin D2 and D3) in the blood, as well as ratio of 25(OH)D3 to 24,25(OH)2D3. This ratio reveals how effectively your body absorbs and utilises Vitamin D, offering insights into your Vitamin D metabolism. Reflecting your Vitamin D levels over the past 1-2 months, a healthy blood level in the range of 30-50 ng/mL can play a key role in supporting metabolic, heart, brain, and immune health as part of a balanced lifestyle.
