Who is this test for?
This test is suited to anyone who would like to quickly get an indication of whether they are deficient in vitamin D. Vitamin D is essential to keep us healthy, yet up to a quarter of the UK population does not get enough of this vital vitamin. During winter months, sunlight levels in the UK are not strong enough for our bodies to make as much vitamin D as we need, and our levels may become deficient.
Some groups are more at risk of deficiency; these include women who are pregnant or breastfeeding, people aged 65 years and over, or people with darker skin, although vitamin D deficiency can affect anybody. This test is suited to anyone who would like a quick way to gain an indication of whether they are vitamin D deficient.
What you will discover
This rapid test will give you a good indication if your vitamin D levels are sufficient (>30ng/ml), insufficient (10-30ng/ml) or deficient (<10ng/ml).
Vitamin D is essential to keep us healthy. It helps to regulate the amount of calcium and phosphate we have in our bodies, allowing our cells to function effectively and keeping our bones and teeth strong.
Vitamin D deficiency may lead to a loss in bone strength. Reduced bone strength can create difficulties with walking and lead to an increased risk of fractures. It is also associated with several other health risks, so taking a test to help spot a potential deficiency early could help avoid more serious problems in future.

Intended use
This test can be used to screen for vitamin D deficiency and provides a preliminary test result based on a simple home blood test. It gives you a semi-quantitative analytical result. This means that while it will give you a good indication of whether you have too little or too much vitamin D in your blood, you’ll need a secondary analytical test if you require your specific levels of vitamin D.
