The Vitamin K Test measures blood levels of vitamin K, a nutrient essential for blood clotting, bone strength, and heart health. Deficiency may cause easy bruising, excessive bleeding, or weakened bones, and can result from poor diet, liver disease, or malabsorption. Doctors order this test to investigate clotting problems, monitor anticoagulant therapy, or assess nutritional status. Results help guide treatment, supplementation, and long-term health management.

The Vitamin, Mineral & Nutrient Deficiency Comprehensive Lab Panel includes 40 tests and 134 biomarkers to review vitamin status, mineral balance, iron storage, anemia patterns, B-vitamin function, methylation, bone-mineral balance, protein nutrition, trace elements, inflammation, liver and bile flow, kidney and urine health, metabolic wellness, and nutrient-related fatigue. Includes vitamin D, A, B1, B6, B12, folate, magnesium, zinc, copper, selenium, iodine, ferritin, and more.

Patient must be 18 years of age or older

The Vitamin, Mineral & Nutrient Deficiency Comprehensive Plus Lab Panel includes 47 tests and 188 biomarkers to review vitamins, minerals, amino acids, fatty acids, antioxidants, mitochondrial nutrients, protein nutrition, iron, methylation, bone-mineral balance, malabsorption, liver, kidney, urine, and metabolic wellness markers. Includes B vitamins, A/C/D/E/K, magnesium, zinc, copper, selenium, iodine, CoQ10, OmegaCheck, glutathione, and more.

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, Mineral & Nutrient Deficiency Advanced Lab Panel includes 30 tests and 119 biomarkers to review vitamin status, mineral balance, iron storage, anemia patterns, B-vitamin function, methylation, bone-mineral balance, protein nutrition, trace elements, inflammation, liver and bile flow, kidney and urine health, metabolic wellness, and nutrient-related fatigue. Includes vitamin D, A, B1, B6, B12, folate, magnesium, zinc, copper, selenium, iodine, ferritin, and more.

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 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.

 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 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 B6 Test measures pyridoxal phosphate levels in blood to evaluate vitamin B6 status. Deficiency may cause anemia, confusion, irritability, depression, or weakened immunity, while high levels from supplementation may lead to nerve damage. Doctors use this test to investigate neurological symptoms, nutritional health, or metabolic disorders. Results provide essential insight into vitamin balance, nerve health, red blood cell production, and overall wellness.

The Vitamin B7 Test measures biotin levels in the blood to assess nutritional status and detect deficiency. Biotin is essential for energy metabolism, enzyme activity, and maintaining healthy hair, skin, and nails. Low levels may result from poor diet, genetic conditions, alcoholism, or long-term antibiotic use, leading to fatigue, hair loss, or skin rashes. Doctors use this test to diagnose deficiency, monitor supplementation, and support overall metabolic health.

The Vitamin B3 Test measures niacin levels in the blood to evaluate nutritional status and detect deficiencies. Niacin is essential for energy metabolism, DNA repair, and nervous system function. Low levels may lead to pellagra, with symptoms such as diarrhea, dermatitis, dementia, and fatigue. Doctors use this test to assess dietary intake, investigate unexplained symptoms, and monitor patients on supplementation or therapy for metabolic health.

The Vitamin B5 Test measures pantothenic acid levels in the blood to assess nutritional status and detect deficiencies. Vitamin B5 is essential for energy metabolism, hormone production, and synthesis of coenzyme A. Low levels may cause fatigue, irritability, digestive upset, or neurological issues, often linked to poor diet or malabsorption. Doctors use this test to confirm deficiency, guide supplementation, and monitor overall metabolic and nutritional health.

The Vitamin A Test measures blood levels of vitamin A, a nutrient essential for vision, immune function, reproduction, and skin health. Low levels may indicate malnutrition, fat malabsorption, or liver disease, while high levels may suggest toxicity from over-supplementation. Doctors use this test to investigate night blindness, frequent infections, or poor wound healing. Results provide vital insight into nutritional status, metabolic function, and overall wellness.

The Vitamin B12 and Folate Panel Test measures blood levels of vitamin B12 and folate to evaluate nutritional status, red blood cell production, and nervous system health. Deficiencies may cause anemia, fatigue, weakness, neuropathy, or cognitive decline, while elevated levels can indicate liver or kidney disease. Doctors use this panel to diagnose deficiency, monitor therapy, and assess absorption disorders such as pernicious anemia, Crohn’s disease, or celiac disease.
