Vitamin D Health Check Test
This Vitamin D Health Check will be able to test your vitamin D levels in the body. If you are lacking in vitamin D it may contribute to you suffering from a range chronic diseases. Maintaining Vitamin D levels protects the body from a wide range of diseases.
Including viruses, cardiovascular disease, bone disease including osteoporosis, rickets and osteomalcia, autoimmune disease (such as multiple sclerosis and rheumatoid arthritis), strokes, nervous system disorders (such as Parkinson’s Disease) and type 1 and 2 diabetes. Depression and breast, prostate and colon cancer have also been linked to Vitamin D deficiency.
What is Vitamin D
Vitamin D, a fat soluble vitamin, is more appropriately categorized as a pro hormone. Vitamin D is metabolised by hepatic 25-hydroxylase into 25-hydroxyvitamin D and by renal 1α- hydroxylase into the active form 1,25- dihyroxyvitamin D. This is responsible for the modulation of calcium absorption and inflammatory responses. Low circulating levels of 25-hydroxyvitamin D Is the most reliable marker of Vitamin D deficiency.
Causes of Vitamin D Deficiency
- Deficient production
- Decreased input due to seasonal lack of exposure to sunlight
- Anything that interferes with the penetration of solar ultraviolet radiation into the skin will diminish the cutaneous production of Vitamin D3
- Dietary intake is low
- Marked decrease in the capacity of the human skin to produce vitamin D in the elderly
- Impaired absorption due to kidney or digestive diseases
Foods Rich In Vitamin D
They are a number of foods which are rich in vitamin D, amongst the best for Vitamin D are fish, especially mackerel, salmon and tuna. They are also small amounts of vitamin D in foods such as cheese, egg yolk and liver found in beef.
How Does The Vitamin D Health Check Test work ?
This test work by using ELISA based technology to determine levels of 25-Hydroxyvitamin D and other metabolites in serum or plasma. Calibrators, controls and samples are diluted with biotin labelled 25-OHD.
Diluted samples are incubated for 2 hours at room temperature before washing. Enzyme labelled Avidin is added and binds selectively to complexed Biotin and following a further wash step colour is developed using TMB. Colour produced is proportionate to the concentration of 25-OH D.
The test is carried out by taking a pin prick sample of blood from your finger. the blood is then sent off to the lab for analysis and you should receive your results in around 10 to 15 working days from the day the lab receives your sample.
This test is not suitable for anyone under the age of 18 years.
