What is a Vitamin D test used for?
The vitamin D test is used to monitor or screen vitamin D deficiency, bone malformations and weakness, body pains, etc.
What is included in the Vitamin D test?
The test measures total vitamin D content in the blood (25-hydroxy vitamin D). Additionally, the levels of vitamin D2 (25-hydroxy vitamin D2) and vitamin D3 (25-hydroxy vitamin D3) will also be measured.
- Vitamin D2– Vitamin D2 is also known as ergocalciferol. The liver converts vitamin D2 into 25-hydroxy vitamin D2. Some sources of vitamin D2 include mushrooms, fortified foods, and dietary supplements.
- Vitamin D3– Vitamin D3 is also referred to as cholecalciferol. Like vitamin D2, vitamin D3 is converted into 25-hydroxy vitamin D3 inside the body. Our body can synthesize vitamin D3 when the skin is exposed to sunlight. It can also be supplemented with animal foods like fish, egg yolk, etc. Vitamin D3 is more effective in raising the total vitamin D levels than vitamin D2.
Procedure for the Vitamin D test
The vitamin D test is similar to other routinely performed blood tests.
- A trained phlebotomist will draw a small amount of blood by inserting the needle into the vein.
- The collected blood sample will be transferred to a small vial or test tube. The sample will then be sent to a partner lab for further processing.
- While inserting the needle into the vein, slight pain may be experienced in the arm. However, the pain will reduce immediately. Some individuals may also experience redness and swelling at the needle insertion site.
- The procedure usually lasts for about 5-10 minutes.
How to prepare for a Vitamin D test?
No special preparations are needed for a Vitamin D test. Disclose all the medications you are taking to your healthcare provider before the test.
Things to consider after the Vitamin D test is complete
No special considerations or precautions are needed once the test is complete. Once the result is available, please consult your doctor. The doctor would suggest further diagnostic tests or prescribe medications based on your results. Please do not self-diagnose disorders based on the Vitamin D report.
What types of disorders can Vitamin D test detect?
The Vitamin D test can diagnose vitamin D deficiency disorders like rickets in children and osteomalacia in adults.
How much does a Vitamin D test cost?
The cost of a Vitamin D test in India varies across different cities. The charges for the test ranges from Rs. 580 to Rs. 1615.
Disclaimer: The value varies based on location, time, and your preferred lab partner.
How long does it take to get the results for the Vitamin D test?
You can expect to get the results for the Vitamin D test within 24 to 48 hours after the sample is collected. However, in certain cases, depending on the location, medical advice, and preferred lab partner, it may take longer.
What do abnormal Vitamin D test results indicate?
Elevated levels of Vitamin D in the blood indicate excess supplementation of Vitamin D pills or foods rich in Vitamin D. Lower levels of vitamin D in the blood may indicate the following-
- The patient is not getting enough exposure to sunlight.
- The patient is having trouble absorbing Vitamin D.
- The patient is not getting enough Vitamin D supplementation
A low vitamin D level may also indicate that the body is not synthesising enough Vitamin D. This can happen in individuals who have underlying kidney or liver diseases.
Disclaimer: Please consult with your doctor for interpreting the test reports.
Is Vitamin D a definitive test?
Yes, vitamin D is a definitive test for the screening of vitamin D deficiency. However, for an accurate diagnosis of bone disorders like rickets, osteomalacia, and osteoporosis, the doctor would recommend X-ray or MRI scans, bone mineral density tests, and other blood tests that measure the levels of calcium, phosphorus, and magnesium in the blood.
How to read the Vitamin D report?
Once the results are available, it is advised to discuss the report with your doctor. However, the following table can be referred to for interpretation.
|Total 25-hydroxy vitamin D level (ng/mL)||Interpretation|
|<10 ng/mL||Severe deficiency|
|10-30 ng/mL||Mild to moderate deficiency|
|30-50 ng/mL||Optimum levels|
|51-70 ng/mL||Upper normal|
Vitamin D test at home – how does it work?
The Vitamin D test is just like any other blood test. A lab technician visits your home when you book your tests through the MFine app. The lab technician first cleans the arm and then inserts a syringe into a vein. The required amount of blood is then taken into a vial. The lab technician then removes the needle and places cotton wool or a bandage over the prick.
Are there any risks involved with a Vitamin D test?
The Vitamin D test does not involve any risks. Some people may experience pain, swelling, and redness at the site of needle insertion.
What can affect the results of a Vitamin D test?
The results of Vitamin D tests are not affected by food or fasting. However, do tell your healthcare provider about the medications and nutrient supplements you consume, as they can affect the results of the test.

How does the Vitamin D test work?
Vitamin D exists in two forms, Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol). In the liver, the vitamin D2 and D3 get converted into their active forms, 25-hydroxy Vitamin D2 and 25-hydroxy vitamin D3, respectively. This test measures the total amount of 25-hydroxy Vitamin D (sum of 25-hydroxy vitamin D2 and 25-hydroxy Vitamin D3 levels) in the blood. Low levels of total Vitamin D indicate Vitamin D deficiency.
What are the symptoms associated with Vitamin D deficiency?
Some symptoms of vitamin D deficiency include the following-
- Fatigue and tiredness
- Bone pain
- Back pain
- Impaired or poor wound healing
- Muscle pain and muscle cramps.
- Anxiety and depression
- Hair loss
What are the risk factors for developing Vitamin D deficiency?
Some common risk factors for developing vitamin D deficiency include the following:
- Inadequate exposure to the sun by spending time indoors.
- Dark-skinned people have a higher risk of developing Vitamin D deficiency.
- Vitamin D levels tend to be lower in aged individuals.
- Consumption of medications such as corticosteroids, statins, phenytoin, etc., for prolonged periods, interferes with the metabolism of Vitamin D.
- Having chronic liver disease, kidney diseases, or hyperthyroidism.
- Having health ailments like Celiac disease or Crohn’s disease, which affect the absorption of nutrients.
- Being overweight or obese.
- Lower consumption of fish and dairy products.
- Patients who underwent gastric bypass surgery.
- People with cancer such as lymphoma
- People with bone disorders like osteoporosis.
- Malabsorption of Vitamin D.
How much Vitamin D should an individual consume?
The recommended dietary allowance of Vitamin D tends to vary with age and underlying disease conditions. The doctor would recommend vitamin D supplements based on individual needs. The following table provides a reference for the daily allowance of Vitamin D.
|Recommended dietary allowance (IU/day)||Upper limit (IU/day)|
|Infants 0-6 months||400||1,000|
|Infants 6-12 months||400||1,500|
|Children 1-3 years old||600||2,500|
|Children 4-8 years old||600||3,000|
|People 9-70 years old||600||4,000|
|People over 70 years old||800||4,000|
|Females 14-50 years old, pregnant/lactating||600||4,000|
What happens when you consume too much Vitamin D?
Increased intake of Vitamin D supplements can lead to overdose and toxicity. Vitamin D toxicity is known as hypervitaminosis D. Excessive exposure to sunlight does not cause hypervitaminosis D. Hypervitaminosis D can lead to hypercalcemia (high calcium levels in the blood). These conditions could cause the following symptoms-
- Decreased appetite
- Increased thirst and urination
- Confusion and weakness.
- Ataxia (a neurological disorder characterized by slurred speech and poor coordination)
What is the treatment for Vitamin D deficiency?
Depending upon your blood Vitamin D levels, your doctor would suggest Vitamin D supplements or foods rich in Vitamin D. Some foods rich in Vitamin D include-
- Fish like mackerel, tuna, and salmon
- Egg yolks
Foods fortified with Vitamin D are also available. Check the label of food items to check if they have Vitamin D. Some foods fortified with Vitamin D include cereals, milk, dairy products like yoghurt, orange juice, and soy drink. In addition, your treating doctor may also recommend oral or injectable supplementation of Vitamin D.
