Preparation: If you’re taking a supplement containing biotin (also called vitamin B7 or B8, vitamin H or coenzyme R), commonly found in products promoting nail, skin and hair health, we recommend that you wait at least 72 hours from your last dose before taking the test.
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.
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.

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 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.
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 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.
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.
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.
