Vitamin D Laboratory Test
Vitamin D Laboratory Test
Vitamin D is a fat soluble vitamin. Research over the years has identified the importance of Vitamin D to health.
Why test for Vitamin D Deficiency
Vitamin D deficiency can be a serious problem and does not have very obvious symptoms. It increases susceptibility to other more serious conditions. 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.
PLEASE NOTE: These tests can only be carried out on those over 18 years of age.
How does the test work?
Explore Exmoor uses a highly reputable laboratory to carry out our laboratory testing. The test uses a conventional ELISA based technology to determine levels of 25-Hydroxyvitamin D and other metabolites in serum or plasma.
The test requires just a pin-prick blood sample. The test kit will be sent to you on receipt of your order. When you place your order please e-mail your date of birth to us via firstname.lastname@example.org.
The results are normally available in 10 – 15 working days and we will contact you as soon as they arrive.
Additional information on Vitamin D
Vitamin D has been in the spotlight over the past few years. One major reason for this is the increase in cases of Vitamin D deficiency. Vitamin D is a vitamin and pro-hormone which is rarely found in natural foods. Our bodies naturally produce it by synthesising ultraviolet light from the sun. It is required in the body to make proper use of calcium for stronger bones and teeth. Vitamin D deficiency is often the cause of bone diseases in children and adults, including osteoporosis and rickets.
Health experts are becoming more concerned about the impact of not getting enough sunlight in the body. Our summers are wetter than usual, we spend hours cooped up indoors and when we do get out in the sun we tend to cover ourselves in high factor suntan lotions. Added to this, the stresses and strains of modern life are making it increasingly difficult to make our own Vitamin D.
The Government has recently become concerned with the low Vitamin D status of many people in the UK and they advise “that to ensure sufficient intake, the following groups of people should take a vitamin D supplement:
• All pregnant and breast feeding women.
• All infants and young children from 6 months to 5 years of age.
• Older people aged 65 and over
• People who have low or no exposure to the sun.”
Benefits of Vitamin D:
Vitamin D is most commonly known for its role in bone health and the prevention of osteoporosis.
However it is now known to have the following other important functions:
• Plays a major function in our overall health and wellbeing
• Supports the immune system
• Regulates cell growth which could help protect against certain types of cancer
• Aids glucose tolerance
• Helps regulate blood pressure
• Supports good mental health, helping to combat depression
• Low vitamin D levels have been associated with the development of Multiple Sclerosis and Rheumatoid Arthritis
• Helps to protect against Age-Related Macular Degeneration.
Sunlight is necessary for the synthesis of Vitamin D3, which is produced underneath the skin following exposure to sunlight. D3 is also contained in foods such as salmon, mackerel, tuna, sardines, milk, eggs, beef and liver.
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
