I was very impressed by how quickly the test was done, and relatively painlessly. Very quick in and out. You can only get this with someone who's been doing this for 20 years. Come if you're afraid of needles and want steady hands!

Once I checked in, I was seen within 10 to 15 minutes. The receptionist also acted as the person who draws blood. She was perfectly nice but not overly so where it felt inauthentic. I was out after about 5 minutes worth of blood drawn, so I'd say the whole experience took about 20-25 minutes. Space was overall clean. It's a very unassuming location just down from Park Avenue, I believe. Blink and you might miss it.

Latest Vitamin D Test Updates

Oct 31, 2022
A surge in respiratory syncytial virus is putting severe strain on children's hospitals nationwide. Hospitals first began seeing the unseasonable RSV rise in August. Now, many are reporting a case increase of over 300 percent compared to last month. (Becker's)

Vitamin D Test FAQs

  • How much does a vitamin D test cost?

    The cost of a vitamin D test is often based on factors including testing provider rates, your geographical location, and whether your health insurance plan covers this test. Your health plan may cover vitamin D testing if your doctor considers this test to be medically necessary, though at-home vitamin D tests may not be covered by your health plan. Ask the vitamin D testing provider to verify the costs associated with a vitamin D test.

  • Does insurance cover vitamin D testing?

    Your health insurance plan may cover the cost of vitamin D testing if your doctor determines that this test is medically necessary based on your symptoms and health condition. Vitamin D tests are usually ordered if you have symptoms of vitamin D deficiency or meet risk factors of vitamin D deficiency. Contact your health insurance provider directly to learn more about your benefits and coverage.

  • Who should get a vitamin D test?

    Anyone can benefit from getting a vitamin D test, as this test can determine whether you are getting the amount of vitamin D needed to maintain optimal health and effectively ward off illness and disease. A vitamin D test is also recommended for those who have symptoms of vitamin D deficiency or meet risk factors of vitamin D deficiency such as having osteoporosis, being obese, or having a dark complexion.

  • How do they test for vitamin D deficiency?

    Vitamin D deficiency can be diagnosed using a vitamin D blood test. In the bloodstream, vitamins D2 and D3 convert into 25-hydroxy vitamin D, which can be measured by a vitamin D test to determine whether or not you are deficient. The vitamin D blood test involves drawing a small sample of blood from a vein in your arm using a tiny needle. Your sample is then evaluated in a lab to determine whether or not you have vitamin D deficiency.

  • How do I read vitamin D test results?

    Vitamin D ranges are typically measured as nanograms per milliliter (ng/mL). A normal range is considered any level between 20 and 40 ng/mL, though some medical professionals consider a normal level to be between 30 and 50 ng/mL. Your doctor or the vitamin D test provider can often help you interpret the results of your vitamin D test.

  • What does low vitamin D mean?

    Having low vitamin D levels may indicate that you are not getting enough vitamin D in your diet or that you are not spending enough time in the sun to allow your body to generate vitamin D. Low vitamin D levels may also indicate that you have an underlying medical condition interfering with your body’s absorption of vitamin D. Your doctor can work with you to identify and treat the root causes contributing to low vitamin D levels.

  • How long does it take to get vitamin D test results?

    Vitamin D test results may come back within a few days to up to a week. Factors that can affect the timing of test results include lab productivity and staffing, and the length of time it takes for your doctor to contact you about your results. Your doctor can give you a more accurate expectation regarding when you can expect to get your test results.

  • Where should I get a vitamin D test?

    Vitamin D tests are available from several healthcare providers, including primary care physicians, urgent care clinics, walk-in laboratories, hospitals, and wellness centers. At-home vitamin D tests are also available for purchase from a number of retailers. Try using Solv to locate top-rated vitamin D testing providers in your area.

  • How accurate are vitamin D tests?

    The 25-hydroxy vitamin D test is currently the most accurate way to measure your body’s levels of vitamin D. However, some factors are known to affect the accuracy of vitamin D tests, such as medications including phenobarbital, isoniazid, and corticosteroids. If you are using medications that are known to affect vitamin D test results, your doctor may ask you to temporarily discontinue these medications within several days leading up to your test.

  • How can I book a vitamin D test through Solv?

    Go to the Solv Home page and type “vitamin D test” into the search field provided. Then, select your location from the dropdown menu to the right. Solv will display a list of top-rated providers in your area that offer vitamin D testing. Select the provider of your choice, then use the contact information listed to call and book an appointment.

About Vitamin D Test

A vitamin D test can be used to determine whether you are getting enough vitamin D or if you are deficient in this vitamin. Vitamin D is essential for strong and healthy bones and a strong immune system. Being deficient in vitamin D may indicate that you are at increased risk for bone conditions, including fractures and osteoporosis.

Vitamin D comes from a variety of foods and is also generated naturally by your body when your skin is exposed to sunlight. Vitamin D deficiency may occur when your diet is lacking in foods that contain vitamin D or when you receive very little sunlight exposure. Vitamin D deficiency can also be caused by kidney disease, liver disease, and other conditions that prevent your body from absorbing vitamin D as it should.

People who can benefit from getting a vitamin D test are those who are experiencing symptoms of vitamin D deficiency, including bone weakness, bone softness, bone malformation, and fractures. People who meet risk factors for vitamin D deficiency can also benefit from having a vitamin D test. Common risk factors for vitamin D deficiency include obesity, a dark complexion, bone disorders including osteoporosis, and having had gastric bypass surgery (a type of weight loss surgery that prevents the body from fully absorbing nutrients).

A vitamin D test is performed as a blood test. During this test, your healthcare provider will draw a small sample of blood from your arm using a tiny needle. Your blood sample will then be sent to a lab, where it is tested for vitamin D levels. A vitamin D test usually takes less than five minutes and involves no special preparation.

If test results show that you are deficient in vitamin D, your doctor will work with you to determine why your levels are low and establish a treatment plan as necessary to increase your vitamin D intake. This may involve modifying your diet to include more foods high in vitamin D, taking vitamin D supplements, spending more time in the sun, or treating the underlying health condition contributing to low vitamin D.
