Vitamin D plays a vital role in maintaining strong bones and supporting glucose metabolism in the body. It also helps in the absorption of calcium and phosphorus from your diet; which are essential for healthy teeth and bones.
A deficiency in vitamin D may result in serious health issues, such as rickets in kids and osteomalacia in adults. For this reason, frequent vitamin D testing is crucial to ensure optimal health and prevent potential complications.
Vitamin D exists in 2 major forms: D2 and D3. Vitamin D2 is primarily obtained from fortified foods such as breakfast cereals, milk, and other dairy products. On the other hand, Vitamin D3 is produced by the body when exposed to sunlight. It is also found in certain foods, including fatty fish (tuna, salmon and mackerel) and eggs.
Both forms are converted by the body into 25-hydroxyvitamin D (25(OH)D), the active form of vitamin D present in the blood.
A vitamin D blood test, thus, measures the level of 25(OH)D in your blood. Abnormal results could indicate various health concerns, including nutritional deficiencies, organ damage, bone disorders, etc.
The vitamin D test is mainly used to monitor bone health and diagnose conditions related to vitamin D levels. It is also helpful in managing chronic diseases such as asthma, psoriasis, and other autoimmune conditions where vitamin D plays a role in overall health.
We recommend a vitamin D test for patients exhibiting symptoms of deficiency or those at high risk. If you are experiencing any of the following symptoms, it’s important to consult with us to determine whether testing is necessary:
Additionally, we recommend testing for individuals with risk factors for vitamin D deficiency, including:

A vitamin D test entails removing a blood sample from a vein in your arm. The sample is then sent to the lab for examination. No special preparation is required for this test, making it simple and convenient.
Once we receive the laboratory results, we carefully review them. Here’s what they might indicate:
This could result from taking too many vitamin D supplements, potentially leading to damage to your blood vessels or body organs.
