Vitamin D is a group of compounds essential proper growth formation teeth bones. This test the level of vitamin D in the blood.
Can measure two types of vitamin D in blood, 25-hydroxy vitamin D and 1, 25 di hydroxy vitamin D.
25 hydroxy vitamin D is the main form found in blood.
What is the importance of vitamin D?
Vitamin D effects on the metabolism of calcium and phosphorus and bone health. Believes that vitamin D is important to maintain the normal function of many tissues and non-structural such as muscle (including heart muscle), improve the immune system and ability to resist infections, as well as to enlarge the cells and differentiation.
Studies have shown that vitamin D may be useful as adjunctive therapy for tuberculosis andpsoriasis , andmultiple sclerosis , or for the Prevention of certain types of cancer. May increase the insufficiency of vitamin (D) the risk of developing Type I diabetes or cardiovascular disease (insulin resistance or high blood pressure or inflammation of low degree) or impaired function of the brain (such as depression). However, did not clarify the roles of the physiological microflora of vitamin D and its impact on these diseases and the importance of these roles.
Natural levels of vitamin D in the body
You have to get people healthy adults in the age group between 19 – 50 years about 200 international units of vitamin (D) per day. Have to get older people on higher levels to ensure the survival of healthy bone. Recommendations for between the ages of 51 and 70 is 400 IU, and to 600 IU for people over the age of 70.
Why is the analysis of the vitamin D?
Analysis uses Vitamin D to achieve:
- What if there is a weakness or deformity in the bone or the metabolism of non-normal calcium (which reflects his calcium is normal, phosphorus, and PTH) occur as a result of the transfer or increase vitamin (D).
- Help diagnose or monitor problems in the functions of the thyroid gland so that hormone PTH is necessary for activation of vitamin D.
- Screening of persons at risk of cash dramatically, as recommended by the foundation osteoporosis National Institute of Medicine and the endocrine glands.
- Assist in monitoring the health status of individuals with diseases interfere with fat absorption, such as cystic fibrosis andCrohn’s disease, because vitamin D is a fat-soluble vitamin and is absorbed from the intestine like a fat.
- Control of persons who have undergone surgery, gastric bypass, and may not be able to absorb enough vitamin D.
- Assistance in determining the effectiveness of treatment when prescribing vitamin D, calcium, phosphorus, and / or supplements magnesium.
When to request analysis of vitamin D?
Analysis of 25-hydroxy vitamin D
When calcium is low and / or the person suffers from the symptoms of vitamin D deficiency, such as bone malformation in children (rickets) and bone weakness or softness, or fracture in adults (osteomalacia), so the analysis of 25-hydroxy vitamin D is usually required to determine the probability of a lack of vitamin D.
Can request testing when the individual is known to be at risk of deficiency of vitamin D. the elderly, and persons who are not exposed to the sun, and those who suffer from obesity excessive, and those who undergone surgery in the stomach, and / or who suffer from malabsorption of fat are at increased risk of vitamin deficiency (d). Include also this group of people with dark skin and women in the stage of breastfeeding.
Often called the analysis of 25 – hydroxy vitamin D before the individual begins drug therapy for osteoporosis.
Analysis of 1, 25 dihydroxy vitamin D
May be requested this test when suspected kidney disease or abnormalities in the enzyme that converts 25-hydroxy vitamin D to 1, 25 dual-hydroxy vitamin D.
In rare cases, this check can be made when calcium is high or a person has the disease may result in excessive amounts of vitamin D, such as sarcoidosis or some forms of lymphoma (because immune cells may make 1, the 25 binary-hydroxy vitamin D).
When vitamin D or calcium, phosphorus or magnesium necessary, is sometimes measured levels of vitamin D to monitor the effectiveness of treatment.
What do you mean as a result of analysis of vitamin D?
Although there are differences in the methods of analysis of the vitamin D, used for most laboratory periods similar reference.
Identify the Endocrine Society America vitamin D deficiency if the level of 25 hydroxy vitamin D in the blood of less than 20 nano grams / ml (50 Nano Mol / liter) and vitamin (D) if the level ranges between 21-29 ng / mL (52.5 – 72.5 Nano-mol / L).
Conclusion the Institute of Medicine in the United States that the level of 25 hydroxy vitamin D of 20 ng / ml (50 Nano mol / L) or higher is suitable for bone health and that levels greater than 30 ng / mL does not provide effects significantly better. However, it is fair to say that the level of 25 hydroxy vitamin D associated with protection from many of the other disorders associated with the recent transfer of vitamin D is controversial.
25 hydroxy vitamin D
May mean a low level of 25-hydroxy vitamin D in the blood that the person does not get enough periods of exposure to sun or enough vitamin D food to meet the needs of his body or that there is a problem in its absorption from the intestine.
From time to time, it can interfere with medications used to treat seizures, particularly phenytoin (Dilantin) with the production of 25-hydroxy vitamin D in the liver.
There is some evidence that vitamin D deficiency may increase the risk of some cancers andimmune diseases and cardiovascular diseases.
The high level of 25 hydroxy vitamin D usually results from supplements in excess of multivitamin tablets or other dietary supplements.
Of 1, 25 dihydroxy vitamin D
Can be Level 1, 25 there vitamin D are low in the case of kidney disease which is one of the changes that occur when a persons suffering from kidney failure early.
May happen high level of 1, 25 dual-hydroxy vitamin D when there is a hormone see a plus or when there are diseases such as sarcoidosis or some lymphomas, which can be manufactured of 1, 25 dual-hydroxy vitamin D outside the kidney.
High levels of vitamin D and calcium can lead to calcification and damage organs, especially the kidneys and blood vessels.
How can I get vitamin D to avoid any shortages?
Is to get vitamin D naturally during exposure to the sun. Enjoy people with white skin the ability to get this vitamin easily because they have less melanin to protect their skin (this is also why their skin to sunburn easily). Often has dark skinned people in cold regions such as Northern Europe to taking supplements of vitamin D because they don’t get enough of this vitamin through the sun, naturally, because of the low sun in the cold winter months.
But, you must get vitamin D during the winter because it helps in the treatment of winter depression, seasonal, and often feel upset and sad when we are making of vitamin D, think about the happy feeling you feel in the early spring when the sun shines while it’s still cold.
