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.

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.

The intensity of the test line will tell you whether your Vitamin D level is Deficient, Insufficient, Sufficient or Toxic.
