The Role of Nutrition Tests

Dietary choices account for health and wellness across all ages. When you’re eating a nutritionally sound diet, you’re getting an array of vitamins, minerals, and other nutrients. As a result, you have abundant energy, improved mood, protection against infection and other immune system invaders, and much more.

But when your diet lacks important nutrients, or you skip meals or overeat, you may be at risk for health issues such as type 2 diabetes, obesity, and other metabolic disorders. You may also have a vitamin deficiency due to medical conditions such as kidney disease, liver failure, or inflammatory bowel disease. Vitamin blood tests can pinpoint areas where you need some extra nutritional support.

Types of Vitamin and Nutrition Tests

Nutrition blood tests, such as the Basic Vitamin Panel or the Comprehensive Vitamin Profile Blood Test, can give you a general overview of multiple vitamin and mineral levels in your body. You may also choose a vitamin deficiency test that focuses on specific nutrients. And if you’ve recently changed to a plant-based diet, the Optimal Vegan/Vegetarian Profile Blood Test helps detect potential imbalances that need to be addressed.

What Blood Tests are Done to Check Vitamin Deficiency?

There are several vitamin deficiency tests to check levels of nutrients, such as:

When to Get Vitamin and Mineral Levels Checked

Your doctor may recommend a blood test for vitamin levels if you have symptoms indicative of a nutrient deficiency or a medical condition that may prevent you from properly absorbing certain nutrients. Your healthcare provider may also use a nutrition blood test—either on its own or in conjunction with food sensitivity tests—to help diagnose a medical issue. You can also use vitamin blood tests to monitor your overall nutritional wellness.
