How To Choose the Best Vitamin Deficiency Test

Home vitamin deficiency tests are convenient, but they are usually limited. A vitamin deficiency test performed at a lab is the pinnacle of accuracy but can be a hassle for some. The choice between at-home vitamin deficiencies tests and laboratory tests can be confusing and difficult. Understanding a few basics can help.

Compounds Measured

A vitamin and mineral deficiency test will measure the levels of a few specific compounds. They generally focus on common vitamin deficiencies rather than testing for a longer list of nutrients. However, most people don’t know what deficiencies they should test. As a result, it can be difficult to decide between tests that measure different deficiencies.

An at-home vitamin blood test usually only measures for a specific vitamin or two. Home vitamin deficiency tests often test for vitamin D levels. Other commonly measured vitamins in an essential vitamin test include:

• Vitamin B12
• Folic Acid (B9)
• Vitamin C

Iron deficiency is common, so a vitamin test may also measure other nutrients, like iron levels.

Accuracy

A blood test for vitamin levels is usually fairly accurate. However, the results are only as good as the sample. One danger with an at-home vitamin blood test is that the sample can be corrupted, either when collected or during shipping. A vitamin blood test performed entirely at a lab is more accurate. 

Labs have to meet standards set by the government, such as those outlined in the Clinical Laboratory Improvement Amendments of 1988, whether they are home vitamin deficiency tests or administered in a lab.

Affordability

Blood tests can be expensive, with the price often scaling with the number of nutrients measured. A vitamin and mineral deficiency test that measures common vitamin deficiencies, mineral deficiencies, and other health indicators can cost hundreds of dollars. A more limited blood test for vitamin levels, measuring only one or two vitamin levels, is usually under $100.

Ease of Use

A vitamin and mineral deficiency test requires a small blood sample. For a vitamin test that is performed at home, a simple finger prick test is usually all that is required. On the other hand, vitamin deficiency tests performed in a lab are handled entirely by professionals.

Common Vitamin Deficiencies

The point of a vitamin test is to determine if you suffer from any vitamin and mineral deficiencies. However, it’s impossible to test the levels of each vitamin. Instead, the most common vitamin deficiencies are tested. They work as reliable indicators of other vitamin deficiencies. The most common vitamin deficiencies include:

• Vitamin B6
• Vitamin D
• Vitamin C
• Vitamin B12
• Vitamin A
• Vitamin E
• Vitamin B9 (folic acid)

Minerals are also important to good health, though many people are deficient. Many people, particularly women, struggle with iron deficiency [1]. These are also among the vitamins that help with weight loss, so if you’re struggling to lose unwanted weight, consider supplementing.

Common Effects and Symptoms of Vitamin Deficiency

Vitamin deficiencies are surprisingly common. The WHO estimated that almost one-quarter of people around the world suffer from nutritional deficiency [2]. 

Even in the United States, almost 10% of people are deficient in at least one important nutrient. It’s not just a number. People who are nutrient deficient may be experiencing symptoms that are debilitating or face an increased risk of health conditions.

• Vitamin B6 – A B6 deficiency is the most common in the US. It’s linked with dry skin, depression, and a weakened immune system. Some conditions can result in B6 deficiency, such as Celiac disease [3].
• Vitamin D – Vitamin D deficiency can cause issues with bone health, particularly for children. On the other hand, sufficient vitamin D can reduce the risk of heart disease [4]. Consider researching the best vitamin D supplement.
• Vitamin C – A lack of vitamin C leads to scurvy, which can result in fatigue and inflammation. Scurvy can become very serious [5].
• Iron – Iron deficiency, anemia, in other words, is another very common issue. It can result in fatigue, confusion, and more serious issues [6].

Groups At-Risk for Vitamin Deficiency

While anyone with poor nutrition may face a nutrient deficiency, there are some groups that face particular risks.

• Pregnant women – Any nutritional deficiency is a problem due to the developing child. Iron deficiency is common, so a vitamin and mineral deficiency test may be best for them.
• Children – Developing children require lots of nutrients but often face vitamin C and vitamin D deficiency.
• Older Adults – Seniors may have trouble eating and digesting. They may also struggle with vitamin D deficiency.
• Restricted nutrition – Anyone on a vegetarian or vegan diet may struggle to get certain vitamins. Home vitamin deficiency tests can help them monitor their nutrition.

What Do I Do About Vitamin Deficiency?

You’ve taken an at-home test or one at a laboratory, and you’re surprised to discover that you’re not getting enough nutrients from your diet. Even if you only tested blood levels of a few key vitamins, those can be indicators of wider deficiencies. It’s a problem, but one that is easy to resolve. Just add more of those vitamins into your diet. Read more about the best diet plans to help incorporate important vitamins into your diet.

Adding fresh vegetables is a great idea. However, a simpler and more reliable way to boost the levels of multiple vitamins is to take a nutritional supplement. How long does it take for vitamins to work? This depends on the vitamin but can vary from a few days to several months.

Vitamin Deficiency Test FAQ

Do you have any questions about using a vitamin test kit and understanding the results? See if we answered them below.

How Can I Get My Vitamin Levels Checked?

You can head to your doctor with your concerns. However, you can also directly assess your vitamin levels by taking a vitamin and mineral deficiency test. You can get a vitamin blood test in the mail. Alternatively, you can have a more accurate blood test for vitamin levels performed when you utilize labs through one of the services on our list.

Can I Test My Vitamin Levels at-home?

It’s possible to take a blood test for vitamin levels without having to leave your home. Companies like Vitl and LetsGetChecked will ship you an at-home vitamin deficiency test that requires a simple finger prick blood sample. The sample is sent back, with results available in a few days.

A vitamin blood test performed at home may not be perfectly accurate, however. Additionally, they may test for a few things and not assess mineral levels, for example. A blood vitamin test performed at a lab is usually more accurate.

What is a Complete Vitamin Test?

There is no complete vitamin test, as there are many different compounds that can be tested for. A vitamin deficiency test usually only looks at a few markers for nutrient deficiency, such as vitamin D deficiency. Home vitamin deficiency tests may only assess one or two levels, while an essential vitamin test at a lab may measure dozens of variables.

Ranking Methodology Explained

There are lots of different lab and home vitamin deficiency tests to choose from, but it’s possible to narrow your choices if you focus on a few essential factors.

Accuracy

A vitamin blood test obviously needs to be accurate to be useful. Home kits can give you an idea, while lab tests use stricter standards to ensure accuracy.

Cost

A vitamin blood test ordered through a lab can be very expensive. However, there are much cheaper options for vitamin deficiency tests.

Ease of Use

A blood vitamin test performed at home usually only requires a finger prick. Handling the vitamin blood test should be as simple as possible. Lab tests usually don’t require anything from you but your presence, though test costs are higher.

Features

A vitamin and mineral deficiency test can give you a lot of information, but much of it may be difficult to understand. The primary feature of lab and at-home tests is an explanation of what the results mean.

Vitamin Deficiency Tests: Final Thoughts

A vitamin and mineral deficiency test is a simple and affordable way to assess your diet. Ideally, you get all the nutrients you need from the food you eat. However, it’s difficult to ensure you’re getting everything you need. At-home tests like LetsGetChecked offer a convenient option, while tests in a lab are more accurate. Either way, a blood test for vitamin levels can help you be healthier.
