Vitamin D Blood Test


This test is ideal if you are wanting to know your Vitamin D levels. If you are deficient in Vitamin D you may have muscle weakness, pain, fatigue and depression.

Vitamin D is needed to maintain a healthy body. Vitamin D keeps teeth, muscles and bones healthy and strong, It also helps absorb calcium and fight off viruses.



Vitamin D Blood Test

Vitamin D is found in sunlight and foods we eat such as fatty fish and fortified dairy products.

Health conditions such as coeliacs disease, chrohns, poor diet, obesity, kidney and liver disease can cause Vitamin D deficiency along with age, skin colour and mobility (due to not going outdoors much resulting in lack of sun exposure).

As we age our skin had reduced ability to make Vitamin D and the darker our skin the less we are able to make Vitamin D compared to a fair skinned person.

If we suffer with Vitamin D deficiency it can lead to loss of bone density resulting in osteoporosis and increased risk of fractures. In children, in severe cases which is very rarely found in developed countries, it can lead to rickets.

Treatment to Vitamin D deficiency can be sought from increased sun exposure, eating more enriched Vitamin D foods or if suitable taking a supplement.

Testing for Vitamin D deficiency

The test can be performed using a small amount of blood from a finger prick which you can do yourself.

How often should I have a Vitamin D blood test?

We recommend checking your Vitamin levels annually unless you experience any health changes or commence a weight loss programme which involves a restricted diet.
