Understanding Vitamin D2


What is Vitamin D2?

The Vitamin D2 is a blood test that measures the levels of vitamin D2 (ergocalciferol), a form of vitamin D in the body. This test is a key indicator of Vitamin D deficiency. It can be conducted as a part of a routine checkup for assessing bone health, especially if there are symptoms or risks associated with bone weakness, bone malformation, or bone softening. 

Vitamin D2, also known as ergocalciferol, is a vital nutrient found in fortified foods and dietary supplements. It plays a crucial role in calcium absorption, supporting bone health, immune function, cardiovascular health, and muscle function. Ensuring an adequate intake of vitamin D2 is essential for overall well-being.

Your doctor may recommend the Vitamin D2 test if you display symptoms suggestive of vitamin D deficiency, such as bone deformities, weakened immune system, muscle cramps, dental abnormalities, bone pain, fatigue, and more. Additionally, individuals with dietary restrictions, certain conditions affecting nutrient absorption, or undergoing specific medical treatments may also undergo this test. Routine checkups as part of a vitamin D profile may be advised if there are concerns about vitamin D intake or absorption.

No special preparation is required for this test. You can eat and drink as per your daily routine. However, it is advisable to stop taking vitamin D supplements before this test, as they may affect the accuracy of the test results. 

Lab test results may vary across different laboratories. Abnormal test results require an expert interpretation, therefore, never try to self-medicate at home based solely on these results, and always consult a doctor for a proper understanding of the test results. By assessing vitamin D2 levels through the Vitamin D2 testing, doctors can offer tailored recommendations for supplementation, dietary adjustments, or sun exposure to prevent deficiencies and related health problems.

What is Vitamin D2 used for?

The Vitamin D2 test can be done:

  • To assess vitamin D2 levels in the body.
  • To check for Vitamin D deficiency.
  • To determine bone health status.
  • To evaluate the risk of conditions like osteoporosis (bone weakness), rickets (bone malformation), osteomalacia (bone softening) etc.
  • To assess the need for vitamin D2 supplementation or dietary modifications.
  • As a part of routine checkup, especially in individuals with risk factors for vitamin D deficiency. 
  • In individuals with symptoms such as bone deformities, muscle cramps,dental abnormalities etc. suggestive of vitamin D2 deficiency. 
  • To monitor treatment response in individuals who are taking vitamin D supplementation.
  • To diagnose or monitor the function of the parathyroid gland, which can impact vitamin D2 metabolism.

What does Vitamin D2 measure?

The Vitamin D2 test measures the amount of vitamin D2, also known as ergocalciferol, which is a type of vitamin D. It is usually found in plant-based sources such as mushrooms and in some fortified foods. The Vitamin D2 test is ordered to determine if a deficiency, insufficiency, or abnormally high level of vitamin D is present in the body, or to monitor ongoing treatment for a previously diagnosed deficiency.
