There are some risks to getting vitamin D tests. The main risk is that you may collect a sample incorrectly, leading to an invalid test result. If you do not feel confident collecting your own sample, going to a healthcare professional to get a vitamin D test may be a better option.
There is also a risk that your test samples will get lost in the mail, or, rarely, laboratories may mix up results. However, using tracked mail delivery services and laboratories that follow regulations can minimize these risks.

“I found out a few months ago that I had a severe vitamin D deficiency, so I started taking daily Vitamin D supplements. I was curious if these were working and if I was taking a high enough dose, but didn’t want to go through a whole doctors appointment and bloodwork test.
“It was super easy to create an account and register my kit. Everlywell’s app is extremely user-friendly, and they provide QR codes and step-by-step instructions for how to register your kit. It took me less than a minute to register the kit.
“For this test, I did have to prick my finger. The process went a lot smoother than I had expected. The kit came with several tips on how to make it easier, like putting your finger against a hard surface so that you don’t have to push as hard, as well as running your hands under warm water and moving them around to get the blood to flow faster. It was a very quick process and took me longer to prep my finger than it did to collect the sample. The lancet tool they provide was very easy to use and not scary, as it was easy to hold and didn’t show the needle at any point in the process.
“I would definitely recommend this product to our readers. Although I hate getting my finger pricked at the doctor, the Everlywell test kit made it really easy and quick to do at home by myself. I loved using the app and found the entire process of at-home testing to be very clear and quick. It was nice that I got to do the test in the comfort of my own home, on my own time.
“I had a really positive experience with Everlywell. I have used several of their at home tests and have never had any issues. I really like how easy it is to use their app, both to learn how to collect the sample and to use it for receiving results. I never like having to log into a bunch of portals to get my lab results from the doctor, which are then sometimes confusing to interpret. With Everlywell, I got a notification when my results were ready, and simply clicked it and immediately had an understandable read on my vitamin D levels.”

What is the 25-hydroxy vitamin D test?
There are two forms of vitamin D in the blood: 25-hydroxy vitamin D, or calcidiol, and 1,25-dihydroxy vitamin D, or calcitriol. Tests will measure the amount of 25-hydroxy vitamin D in your blood. This is because 25-hydroxy vitamin D is a better indicator of your vitamin D levels and stays in the bloodstream for longer, making it easier to detect.
25-hydroxy vitamin D
If you have a vitamin D test at a doctor’s office, the doctor will take a small blood sample from the arm using a needle. If you take a test at home, you will take a blood sample using a finger-prick test.

How to choose a vitamin D test
Some things you should consider when looking for an at-home test include:
Cost: At-home testing can be expensive, so consider your budget and whether it could be more affordable to get a test with a doctor who accepts your insurance.
Certifications and accreditations: You should always check for CAP, CLIA, and ISO certifications to make sure the company you are buying from will send your sample to reputable and safe labs.
Reviews and reputation: Checking independent reviews from sites such the Better Business Bureau (BBB) can help a person make an informed decision about a company’s reputation.
Vitamin D deficiency
According to a 2022 overview of vitamin D deficiency, around 1 billion people worldwide have a vitamin D deficiency, and 50% of the global population has vitamin D insufficiency.
2022 overview
Although the article states that most people with a vitamin D deficiency will not experience symptoms, some people do.

Another important thing to consider is the source of vitamin D. The overview suggests you should spend 20 minutes a day in the sun. However, this also brings risks of premature aging and skin cancer.

A person should always use sunscreen when outside to protect the skin against the sun’s harmful effects.

How to increase vitamin D
The body makes vitamin D naturally when you expose it to the sun. However, people who are older, live further north, or have a dark skin tone may not be able to create enough vitamin D.
Spending 20 minutes per day in the sun can help increase vitamin D levels. However, it is important to wear sunscreen to protect the skin against sun damage.
20 minutes per day
You can also use vitamin D supplements to increase your vitamin levels. The British National Health Service (NHS) recommends taking 10 micrograms of vitamin D supplements every day during the fall and winter.

Situations include people with insufficient intake of foods containing vitamin D and malabsorption syndromes, such as Crohn’s disease and celiac disease.

Doctors measure vitamin D deficiencies in nanomoles per liter (nmol/L) or nanograms per milliliter (ng/mL). The current staging is as follows:
as follows
• Deficiency: Below 30 nmol/L or 12 ng/mL.

• Inadequate levels: 30 to 50 nmol/L or 2 to 20 ng/mL.

• Adequate levels: 50 to 125 nmol/L or 20 to 50 ng/mL.

• High levels: Above 125 nmol/L or 50 ng/mL.

Samples from at-home tests go through the same lab processing as those from medical professionals in a doctor’s office or clinic. The validation process for at-home testing is the same as for traditional testing that takes place in a lab and clinic.

However, if you take a test at home, you must follow all the test manufacturer’s instructions to avoid invalidating the results.

You can check whether the lab that processes your chosen test has accreditation from the College of American Pathologists (CAP) and certification from the Clinical Laboratory Improvement Amendments (CLIA). You can also check whether the lab’s manufacturing facilities have International Organization for Standardization (ISO) certification.
