What's Tested

Vitamin D

Labcorp’s vitamin D test included in this panel measures the level of 25-hydroxy vitamin D in your blood. Vitamin D helps your body regulate calcium metabolism which in turn helps maintain healthy bones, control infections, reduce inflammation and more. Your skin produces vitamin D through sunlight exposure. Vitamin D is also found in foods such as fatty fish, mushrooms, egg yolks and fortified milks. When you’re deficient in vitamin D, you may experience symptoms like fatigue, muscle weakness and depression. Additionally, you could become more prone to having fractures from falls if you have a vitamin D deficiency.
Vitamin B12

Vitamin B12 plays an essential role in red blood cell formation, cell metabolism, nerve function and more. It’s found in foods such as nutritional yeast, plant-based milks and certain cereals. When you’re deficient in vitamin B12, you may experience symptoms like fatigue, weight loss and loss of appetite.
Folate

A natural form of vitamin B9, folate helps your body make new red blood cells and DNA, and it plays an important role in a fetus’s development. It’s found in foods such as leafy greens, beans, seafood, eggs and more. When you’re deficient in folate, you may experience symptoms like fatigue and weight loss.
Magnesium

Magnesium is a type of electrolyte—an electrically charged mineral—that helps your muscles, nerves and heart work properly. It’s found in foods such as legumes, nuts, seeds, greens and whole grains. When you’re deficient in magnesium, you may experience symptoms like fatigue, muscle cramps, numbness and/or tingling, an irregular heartbeat and more. Magnesium can impact the balance of other electrolytes, including potassium. It is recommended to consult with your healthcare provider to discuss your test results and next steps.
Iodine

This trace mineral supports your thyroid function by helping to produce thyroid hormones. It’s found in foods such as iodized salt, milk, yogurt, cheese, shrimp, cod and tuna. When you’re deficient in iodine, you may experience symptoms like fatigue, weight gain, dry skin, confusion and more.
Zinc

This important mineral helps support your immune system and metabolism. It’s found in foods such as red meat, chicken, oysters, beans, lentils, nuts and chickpeas. When you’re deficient in zinc, you may experience symptoms like weight loss, loss of appetite, decreased immunity and hair loss.

Optimize your diet

Do you wonder if you are eating a well-balanced diet? Our micronutrient testing measures the vitamins (folate, vitamin B12 and vitamin D) and minerals (iodine, zinc, and magnesium) that may be impacted by specialized diets such as vegan or vegetarian.

Identify a nutritional deficiency

Symptoms like fatigue, weight loss or lack of appetite may be related to inadequate nutrition and can go unnoticed. However, symptoms of vitamin and mineral deficiency are often vague and could be signs of other health problems. Testing your micronutrient levels can uncover opportunities to optimize nutritional status.

If you are experiencing concerning symptoms, you should connect with a healthcare provider for guidance.

FAQ

Micronutrients and macronutrients are found in the foods we eat, and our body needs to take in adequate amounts of both to function properly. Micronutrients consist of vitamins and minerals that optimize our body’s performance. Macronutrients include fats, carbohydrates and proteins that provide energy in the form of calories.

This micronutrient test can help identify if you’re deficient in certain vitamins and minerals, empowering you to make informed decisions on your health.

The most common vitamin deficiencies in the U.S. include¹:

Vitamin D
Vitamin B12
Vitamin B6
Folate

The most common mineral deficiencies in the U.S. include¹:

Iron
Iodine
Magnesium
Calcium

Our Micronutrient Test covers five of these widespread deficiencies, as shown in bold above.
Some people are at higher risk of experiencing vitamin and mineral deficiencies as well as “micronutrient inadequacies,” which occur when you get less than the recommended dietary intake but may not have obvious symptoms. People at higher risk include²:

People with gastrointestinal disorders such as Crohn’s disease, celiac disease and inflammatory bowel disease (IBD), given that these conditions can impact micronutrient absorption (folate, vitamin B12, zinc, magnesium)
People who follow a vegan or vegetarian diet, as some micronutrients are more commonly available in animal-based foods (folate, vitamin B12, iodine, zinc)
Older adults, because they may have a reduced appetite, reduced micronutrient absorption and/or reduced exposure to sunshine (which is required for the body to make vitamin D)
People taking certain medications (e.g., proton pump inhibitors) that may affect the body’s ability to absorb micronutrients (vitamin B12 and magnesium)
People with unbalanced, low-quality and/or restrictive diets, which can mean you’re not getting the full diversity of micronutrients you need

Health-conscious individuals and athletes may also be interested in checking that nutritional deficiencies aren’t holding back their performance, recovery and overall health.
