The Vitamin D Panel panel contains 2 tests with 7 biomarkers.

Brief Description: The Vitamin D Panel is an extensive set of tests designed to measure the levels of Vitamin D in its various forms within the body, including 25-Hydroxyvitamin D Total, 25-Hydroxyvitamin D2, 25-Hydroxyvitamin D3, 1,25-Dihydroxyvitamin D Total, 1,25-Dihydroxyvitamin D2, and 1,25-Dihydroxyvitamin D3. This panel provides a comprehensive assessment of an individual's Vitamin D status, which is crucial for bone health, immune function, and overall well-being.

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Fasting preferred, but not required.

When and Why the Panel May Be Ordered

The Vitamin D Panel is often ordered for individuals with symptoms of Vitamin D deficiency or excess, those with conditions affecting Vitamin D metabolism (such as kidney disease or certain autoimmune conditions), or as part of a comprehensive health assessment. It is particularly important for individuals at risk of osteoporosis, those with limited sun exposure, or dietary intake of Vitamin D.

What the Vitamin D Panel Checks For

The panel measures different forms of Vitamin D to provide a detailed view of an individual's Vitamin D status:

25-Hydroxyvitamin D Total: A primary indicator of Vitamin D status, reflecting vitamin D produced in the skin and obtained from food and supplements.

25-Hydroxyvitamin D2 and D3: Measures the individual contributions from plant-based (D2) and endogenous/supplemental (D3) sources.

1,25-Dihydroxyvitamin D Total, D2, and D3: The active form of Vitamin D, important for understanding Vitamin D's role in calcium metabolism and immune function.

Detected Conditions and Diseases

The Vitamin D Panel can detect and aid in the management of:

Vitamin D Deficiency: Leading to bone disorders such as rickets in children and osteomalacia or osteoporosis in adults.

Vitamin D Excess: Which can cause hypercalcemia and associated complications.

Conditions Affecting Vitamin D Metabolism: Such as kidney disease, which can alter the conversion of Vitamin D to its active form.

Clinical Application of Panel Results

Healthcare professionals use the panel results to:

Diagnose Vitamin D Deficiency or Excess: Guiding supplementation or treatment adjustments.

Manage Bone Health: Informing strategies to prevent or treat osteoporosis and other bone diseases.

Monitor Conditions Affecting Vitamin D Metabolism: Assessing and adjusting treatment in conditions like kidney disease or parathyroid disorders.

The Vitamin D Panel offers a thorough evaluation of an individual's Vitamin D levels, providing essential insights for diagnosing deficiencies or excesses, guiding treatment and supplementation, and monitoring conditions that affect Vitamin D metabolism. This comprehensive approach helps in maintaining optimal bone health, immune function, and overall well-being.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.
