Features and Benefits
We get some of it from food, but most comes from sunlight. Vitamin D is also found in oily fish, such as salmon, mackerel and sardines, eggs, fortified fat spreads, fortified breakfast cereals and powdered milk.

What is Vitamin D Deficiency?
Vitamin D is essential for healthy bones. Some people don’t have enough vitamin D – called vitamin D deficiency.
Why do I need this test?
Between October and March, the sunlight in Britain is not strong enough to make enough vitamin D, and up to a quarter of the population has low levels of it in their blood.

How do I perform the Test?
It is very simple – just use the enclosed lancet and capillary tube to transfer a blood sample to the test cassette, then add 2 drops of the buffer solution. You will then be able to read the results after 10 minutes by comparing your results with the colour card that is included. The intensity of the test line will tell you whether your Vitamin D level is Deficient, Insufficient, Sufficient or Toxic.
