The Importance of Having a Vitamin D Test

Low levels of vitamin D can also increase the risk of some cancers, autoimmune diseases, and cardiovascular diseases. Knowing your vitamin D levels can help your doctor identify if you are at risk of developing any of these conditions. Complement your reading by visiting this recommended external resource.

Who Should Get a Vitamin D Test?

Anybody can get a vitamin D test, but some people are at higher risk of having low vitamin D levels. These include:

People with naturally dark skin, as they may need more sunlight exposure to produce sufficient vitamin D.

Elderly people, as they may have a reduced ability to synthesize vitamin D in the skin.

People with a condition that affects the absorption of vitamin D, such as Crohn’s disease, cystic fibrosis, or celiac disease.

People who are obese, as they may need more vitamin D to maintain healthy blood levels.

How Is the Test Performed?

A vitamin D test is a simple blood test that can be done in your doctor’s office or a lab. The test usually involves taking a blood sample from a vein in your arm. Before the test, you may be asked to fast or avoid certain medications or supplements that may affect your vitamin D levels.

What Do the Results Mean?

The results of a vitamin D test are usually reported in nanograms per milliliter (ng/mL) of blood. The optimal range for vitamin D levels is between 30 and 100 ng/mL. If your levels are below 30 ng/mL, you may be at risk of vitamin D deficiency and may need to take supplements or increase your sun exposure. If your levels are above 100 ng/mL, you may have vitamin D toxicity and need to reduce your vitamin D intake.

How Can You Increase Your Vitamin D Levels?

If your vitamin D levels are low, your doctor may recommend taking vitamin D supplements. You can also increase your vitamin D levels by spending more time in the sun, particularly between 10 am and 3 pm when the sun’s UVB rays are the strongest. However, be sure to protect your skin with sunscreen and cover-up clothing, as excess sun exposure can increase the risk of skin cancer. Seeking a deeper grasp of the subject?
