The Vitamin D and B12 Panel measures key nutrients essential for energy, metabolism, and bone health. It includes the Vitamin B12 test and the Cardio IQ™ Vitamin D 25-Hydroxy Test to help assess absorption, detect deficiencies, and provide insight into your body’s balance of vital vitamins for overall wellness and long-term health optimization.

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.

The Vitamin D 1,25-Dihydroxy Test measures the active form of vitamin D in blood to evaluate calcium and phosphorus balance, bone health, and kidney function. Abnormal levels may indicate kidney disease, parathyroid disorders, or problems with calcium metabolism. Doctors order this test when deficiency symptoms don’t match 25-hydroxy vitamin D results or to monitor chronic illness. Results provide vital insight into vitamin D activity, mineral health, and metabolic function.

The Cardio IQ Vitamin D test, also known as a 25-hydroxy vitamin D test, measures the levels of total vitamin D in the blood, including both vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). It provides information about an individual's overall vitamin D status.

 The Vitamin D & K Panel is an important diagnostic tool used to assess the levels of vitamins D and K in the body, both of which play crucial roles in bone health, cardiovascular health, and the immune system. This panel includes the QuestAssureD 25-Hydroxyvitamin D Total with D2 and D3 test, which measures the levels of vitamin D2 and D3 to determine the overall vitamin D status, and a Vitamin K test to assess the amount of this essential nutrient involved in blood clotting and bone metabolism.

The Vitamin D 25-Hydroxy Total Test measures levels of 25-hydroxyvitamin D in blood to evaluate vitamin D status, bone health, and calcium balance. It helps detect deficiency, insufficiency, or toxicity, which can affect immune function, muscle strength, and risk of osteoporosis. Doctors use this test to assess overall nutritional health, monitor supplementation, and support diagnosis of metabolic or endocrine disorders linked to vitamin D.
