About this Panel
Vitamin D is an essential fat-soluble vitamin that is found in only a few foods.
Our main source of the vitamin is through a chemical reaction in the skin that is dependent on sun exposure. Vitamin D is essential for healthy bones, control of cell proliferation and differentiation and modulation of the immune system. We measure the metabolite 25-hydroxyvitamin D in your sample to estimate your vitamin D status. This is our fastest test for vitamin D deficiency with results available next day* if samples are received at our laboratory before noon. p>
Vitamin D plays a critical role in regulating calcium and phosphorus levels in the body, which keep bones, teeth and muscles healthy. Additionally, it plays an important role in immune function, many chronic diseases and mental health. Specifically, it has been associated with cancer, cardiovascular disease and rickets in children and osteoporosis in adults.
Vitamin D is most commonly absorbed from exposure to the sun, although it can also be found in foods such as oily fish, red meat, liver and egg yolks. Vitamin D deficiency is common in the winter months when sun exposure is reduced.
Who is this panel for?
This fast vitamin D blood test is for anyone concerned about their Vitamin D status. Vitamin D deficiency is very common in the UK, especially in the winter months, due to lack of exposure to the sun. Sunlight is essential for the chemical reaction that happens in your skin to produce vitamin D – we are unable to obtain enough vitamin D from food to maintain health. During the summer, any surplus vitamin D that you make is stored in your body for use the following winter. If we don’t make sufficient vitamin D during the summer, then stores are inadequate for the winter. Age is also a factor in vitamin D since as we get older the thinning of our skin diminishes the availability of the components we need to make it. Poor vitamin D status causes poor bone health and has also been associated with many other diseases.

Samples must arrive at the laboratory before 12pm for next-day turnaround. Samples received after 12pm will be turned around within 2 working days.
