At Home Vitamin D Test: What You Should Know

A lack of vitamin D is not uncommon and can arise due to a number of reasons. An at-home vitamin D test can be used to evaluate a person’s levels of vitamin D. Here, we will discuss what a vitamin D deficiency is, the purpose of an at home test, how it works and who may require one.

What Is a Vitamin D Deficiency?

Vitamin D is a fat-soluble component that the body requires for essential processes, including bone and tooth maintenance. It also aids the body’s immune defence against viruses and bacteria. Despite this, research reveals that vitamin D is crucial for more than just bone and immune function. According to some studies, a vitamin D deficiency can be linked to a higher risk of heart problems, autoimmune illnesses, diabetes, and cancer.

Fortunately, determining your vitamin D levels is simple. An at-home vitamin D test can assist you in determining whether your levels are within a healthy, normal range.


What Is the Purpose of An at Home Vitamin D Test?

A vitamin D test determines how much vitamin is present in your blood. These exams can determine whether your body has too much or too little of it. Both the nutrition you eat and the vitamin you get from the sunlight commence out as an inactive state. The kidneys and liver then convert 25-OH D to a chemically activated state. The total level of 25-OH D in the blood is measured in several tests. This is because this type of vitamin D has a lengthier half-life than 1,25-dihydroxy.

How Does It Work?

A blood specimen is required for vitamin D analysis. Calcidiol and calcitriol are the two types of vitamin D found in the blood.  25-hydroxy is a more accurate predictor of a person’s vitamin D status and lasts longer in circulation, making it simpler to measure.

If a patient has acquired a test at a physician’s office, the physician will use a needle to draw a small amount of blood from their forearm. When a person performs a home test, they will use a prick test to obtain a blood specimen.

After blood sample has been safely taken, it will go in a sample bottle and be sent off to a lab to be examined.


When May a Test Be Required?

Anyone can develop a vitamin deficiency depending on their lifestyle choices, dietary habits, and their body’s natural ability to absorb vitamin D.  The following people are at a greater chance of acquiring a deficit:

  • those suffering from gut diseases like Crohn’s disease or stomach cancer
  • those suffering from severe kidney or liver disease
  • those who don’t get enough sun
  • those who have had surgery in the past
