Vitamin D Bloodspot - ZRT
What's Included?

There is no special preparation required before testing.

A BioHub Vitamin D kit for home collection can be mailed to you for a finger-stick collection in the privacy of your home. The Vitamin D test was created to measure both the natural form of Vitamin D (D3) and D2, the form used in many supplements. The same test used to look for a vitamin deficiency can also be used to monitor the effectiveness of vitamin D supplements in maintaining the right amount for optimum health.

Recently, research has shown that vitamin D is important in protecting the body from a wide range of diseases. Disorders linked with vitamin D deficiency include stroke, cardiovascular disease, osteoporosis, several forms of cancer, some autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, type I & II diabetes, depression and even schizophrenia.

Vitamin D is actually a pro-hormone and not technically a vitamin: a vitamin is defined as a substance that is not made naturally by the body but must be supplied in the diet to maintain life processes. But in fact, we make most of our vitamin D when our skin is exposed to ultraviolet light (sunlight). We only get very small amounts of vitamin D from our diet, although increasingly it is added to foods eaten by children, in an attempt to prevent rickets in the population.

A major cause of deficiency is not getting enough sun. This is very common in northern climates where people don’t spend much time outdoors, but even in countries near the equator, women in particular often have much of their skin area covered for cultural reasons, and the use of sunscreen also blocks the formation of vitamin D in the skin.

Vitamin D is metabolized by the liver to a storage form of the vitamin, which circulates in the blood until needed. Enzymes in the kidneys metabolize it further to form the highly active hormone that is involved in essential biochemical processes throughout the body. Testing for vitamin D is therefore an important screening test, especially if you spend much of your time indoors, or live in a colder climate.
