The at-home Vitamin D test measures your Vitamin D levels using a dry blood sample and a physician reviews the results to assess whether your levels are adequate for maintaining healthy bones and muscles.

What is Vitamin D?

Contrary to the name, Vitamin D is a hormone that is produced in the body on exposure to sunlight. The body stores Vitamin D in liver which releases, as necessary, to the kidneys which convert it into an active form that circulates in the blood. Our Vitamin D Home Test kit measures this active form.

Why measure Vitamin D?

Vitamin D is crucial for absorption of calcium and phosphorus, two key minerals for healthy bones and muscles. The age related bone density loss can be accelerated by Vitamin D deficiency, making the bones susceptible to fracture and, in severe cases, may result in Osteomalacia. Vitamin D deficiency in children results in weak and improper bone and muscle development (a condition called rickets).

Exposure and intensity of UVB rays, that are responsible for producing Vitamin D, vary based on several factors including location, season, time of the day, skin tone, clothing, and surrounding. Therefore, our Vitamin D levels vary significantly.

Symptoms of low Vitamin D include muscular weakness, feeling of heaviness in the legs, fatigue or easy tiring, and chronic musculoskeletal pain (i.e., pain related to bones, muscles, ligaments, and joints). Without adequate Vitamin D in the body, symptoms of depression and more frequent infections are commonly observed. Many of these symptoms can be caused by other issues but a blood test for Vitamin D deficiency is an important first step to ensure proper diagnosis. Children, new mothers, elderly, and people with extra weight (as Vitamin D dissolves in fat) are especially at higher risk.

Recent research has shown that 26 different body tissues have Vitamin D receptors making it vital for overall health. Studies indicate Vitamin D plays a key role in preventing and reducing over fifteen different kinds of cancers including cancers of breasts, lung, colon, and prostate. Vitamin D is also crucial for weight loss, muscle strength, bone fracture, healthy heart, and a healthy immune system.

Those residing above the 33rd parallel (regions north of Bakersfield, CA or Flagstaff, AZ or Charlotte, NC) get almost no Vitamin D from sun during winter months (due to low UVB in the sunlight) and may be at higher risk of Vitamin D deficiency. Experts believe a value of at least 30 ng/ml is necessary but 40 ng/ml or more is optimal

The report will also specify what are the expected low and high ranges. It will briefly discuss what your numbers mean and what next steps should be taken to maintain healthy Vitamin D levels.

Q: Can I use my insurance to pay for the test?

A: No. Unfortunately, the insurance process is extremely complex and we are not yet able to negotiate our low prices with them. Our tests are generally cheaper than what you pay for an out-of-pocket test. You do not need to visit a physician or a lab which saves both time and money. The tests include a physician's prescription and review, and we strongly encourage to take the results to your doctor for further consultation. You can typically pay for the tests with your HSA/FSA but we encourage you to talk to your insurance provider before getting an reimbursement from your plan.

Q: How reliable are my results?

A: We have partnered with CLIA-certified labs that are used by physicians across the US. These labs are regulated by the states, as well as Centers for Medicare and Medicaid Services (CMS). Majority of the tests from these labs are FDA approved to ensure they meet the proper regulatory requirements. Additionally, the College of American Pathologists (CAP) requires inter-laboratory tests to ensure the ranges established by each lab do not drift or are not out of acceptable ranges. This is done by regularly testing reference samples between different labs. Finally, the labs test thousands of sample for different age groups and health conditions, and have well established reference data to compare your results against this large pool.

Q: Can you recommend what therapy should I take if my Vitamin D levels are low?

A: As a lab test provider we can only test and report out data from your samples. We are not authorized to provide any medical recommendations. But we strongly encourage you to discuss the results with your doctor for next steps. Vitamin D can be naturally supplemented using sunlight. For more information, please read: All About Vitamin D.
