What is Vitamin D Listed as on a Blood Test?
Have you ever wondered what vitamin D is listed as on a blood test? With the growing concern of vitamin D deficiency, it is important to understand what it means when you see your levels on a blood test. This article will explore what vitamin D is listed as on a blood test, why it matters, and what steps you can take to maintain healthy vitamin D levels.
Understanding Your Blood Test Results: What Does Vitamin D Show Up as on a Blood Test?
Before we dive into what vitamin D shows up as on a blood test, let’s start with what a blood test is. A blood test is a laboratory analysis performed on a sample of blood.
During a blood test, various markers in the blood are assessed to determine if anything is abnormal. One of these markers can be vitamin D levels. Vitamin D is important to measure in the blood because it plays a crucial role in various bodily functions such as calcium absorption, immune system health, and bone development.
What Specifically is Measured in a Vitamin D Blood Test?
A vitamin D blood test measures two types of vitamin D: 25-hydroxyvitamin D (25(OH)D) and 1,25-dihydroxyvitamin D (1,25(OH)2D). The former is the most commonly measured form of vitamin D in a blood test.
25(OH)D is considered the storage form of vitamin D, as it is the form stored in the liver until it is needed. 1,25(OH)2D, on the other hand, is the active form of vitamin D. It is produced in the kidneys and is responsible for regulating calcium levels in the blood.
Why Vitamin D is Important to Measure in the Blood
Vitamin D deficiency has become increasingly common, and studies have shown that up to 40% of adults in the United States are deficient. Vitamin D deficiency can lead to a slew of health issues, including bone loss, osteoporosis, and an increased risk of fractures.
By measuring vitamin D levels in the blood, doctors can determine if a patient is deficient and help them take the necessary steps to correct the deficiency. This can include increased sun exposure, dietary changes, or vitamin D supplementation.

How Vitamin D Levels are Reported in a Blood Test
Vitamin D levels are typically reported as ng/mL (nanograms per milliliter) or nmol/L (nanomoles per liter).
Different Types of Blood Tests Used for Measuring Vitamin D Levels
There are two different types of blood tests that can be used to measure vitamin D levels: the 25-hydroxyvitamin D (25(OH)D) test and the 1,25-dihydroxyvitamin D (1,25(OH)2D) test.
As previously mentioned, the 25(OH)D test is the most commonly performed vitamin D blood test. It is considered to be the best indicator of vitamin D status in the body as it measures the storage form of vitamin D. The 1,25(OH)2D test is not routinely used to measure vitamin D levels because it is not considered to be as accurate of a measure as the 25(OH)D test.
Normal Range for Vitamin D Levels in the Blood
The normal range for vitamin D levels in the blood is considered to be between 30 ng/mL and 80 ng/mL. However, some studies suggest that the optimal range for vitamin D levels should be between 40 ng/mL and 60 ng/mL.
How to Interpret the Results of Your Vitamin D Blood Test
If your vitamin D levels are below the normal range, it may indicate a vitamin D deficiency. If your vitamin D levels are above the normal range, it may indicate that you are taking too much vitamin D supplementation.
What is the Name of Vitamin D on a Blood Test and Why it Matters
Explanation of the Different Forms of Vitamin D
There are two different forms of vitamin D: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol).
Vitamin D2 is primarily found in fortified foods and supplements, while vitamin D3 is synthesized by the body when exposed to sunlight. Vitamin D3 is also found in some food sources such as fatty fish and egg yolks.
What Form of Vitamin D is Measured in a Blood Test
The 25(OH)D test, which is the most commonly performed vitamin D blood test, measures both vitamin D2 and vitamin D3 levels in the blood.
Differences Between the Forms of Vitamin D and How They Affect Health
While both vitamin D2 and vitamin D3 can raise blood levels of vitamin D, research has shown that vitamin D3 is more effective at raising and maintaining vitamin D levels in the body. This is because vitamin D3 is the form of vitamin D that is most easily utilized by the body.
Why it is Important to Know the Form of Vitamin D Measured in Your Blood Test
Knowing the form of vitamin D measured in your blood test can be important because research has shown that vitamin D3 is more effective at raising and maintaining vitamin D levels in the body. If you are supplementing with vitamin D, choosing a supplement that contains vitamin D3 may be more effective at correcting a vitamin D deficiency.
