25HDN, or 25-Hydroxyvitamin D2 and D3, S is a test to help evaluate risk factors associated with vitamin D deficiency. It is also useful as a tool to determine the causes of rickets and osteomalacia (softening of the bones), to monitor Vitamin D levels during replacement therapy, and to diagnose hypervitaminosis D, also called vitamin D toxicity. 25HDN is a simple blood test.
TEST SPECIFICATIONS
Who Is It For?
Vitamin D testing is recommended for:
- Anyone concerned about their well-being, health, and vitamin D levels
- Those who suffer from Seasonal Affective Disorder
- Anyone who receives treatment or therapy for osteoporosis and other bone disorders
- Elderly people, particularly those with insufficient exposure to sunlight
- People with a diagnosis or signs of hypocalcemia or hypercalcemia (too much or too little calcium)
- Anyone suffering from rickets and osteomalacia
- Patients receiving vitamin D therapy who don’t show signs of improvement
- Children who frequently get sick
Why Is It Important?
Vitamin D is a nutrient our bodies need to stay healthy. It keeps our bones strong, aids in calcium absorption, and regulates the function of the parathyroid gland.
Insufficient vitamin D levels can cause:
- Loss of bone density
- Increased susceptibility to viral infections
- Rickets, osteomalacia, osteoporosis and other bone diseases
There is also evidence that may indicate that vitamin D deficiency can contribute to diabetes, high blood pressure, cancer, and autoimmune conditions such as multiple sclerosis.
