It depends on where you have the test done. The cheapest I have found is to order it through LEF.org. It is $47 for members and $63 for nonmembers. They use Laboratory Corporation of America for the tests.
FYI
Life Extension's research has found that if a person is not taking at least 5000IU of vitamin D a day they will likely be below an optimal blood value of 50ng/mL. Life Extension suggests most people take this amount for at least 1 month before doing their vitamin D blood test. Please see our January 2010 magazine article "Startling Findings About Vitamin D Levels in Life Extension Members" for more details.
By eating foods with high vitamin c in them, and recording the difference in your health. How to test for vitamin C: 1. Draw up 2cm3 of lemon/orange juice (or the substance you're wanting to test for vitamin C) into a syringe. 2. Add it drop by drop into 2cm3 of a 0.1% solution of DCIP (a blue dye) 3. The dye will turn colourless if vitamin C is present
To convert yards to feet, we multiply by 3. So, 25 yards is equivalent to 75 feet. To find the cost of 100 feet, divide the cost of 25 yards by 75 feet and multiply by 100 feet: 9.95 / 75 * 100 = $13.27.
Yes, but way of exposure to the sun. Very few foods contain vitamin D so synthesis of vitamin D in the skin is the major natural source of the vitamin. Vitamins A, D, and B12 are stored in significant amounts in the human body, mainly in the liver. But after the stores are gone, there will be a deficiency condition. Well-known human vitamin deficiencies involve thiamine (beriberi), niacin (pellagra), vitamin C (scurvy), and vitamin D (rickets).
In presence of ultraviolet rays of sun Cholesterol in skin is converted to Cholecalciferol. then in Liver it get converted to 25 Cholecalciferol. then in kidney, it get converted to 1,25 Cholecalciferol. Which is active form of Vitamin D. Also called as Calitriol. If execass of Vitamin 'D' is ingested as in Cod Liver intake, then body converts it into 24, 25 cholecalciferol, which is almost inactive form of Vitamin 'D'. You have almost no Vitamin 'D' in diary food or any other food. So almost all people have subclinical vitamin 'D' deficiency, except people living in polar area. (Who almost never get heart attack.) so Vitamin 'D' should be added by government in food. Calcitriol deposites calcium salt in bones, enhance absorption of calcium salts from intestine, Reabsorbs calcium ion from kidney.

For a Vitamin D and 25-hydroxy Vitamin D test, a red and gold tiger-stripe or speckled tube top is typically used.
82306 is the code for Vitamin D; 25 hydroxy, includes fraction(s) if performed 82652 is the code for Vitamin D; 1,25 hydroxy, includes fraction(s) if performed (82307 has been deleted. for 25 hydroxy vitamin D, use 82306) This information is straight out of the CPT 2011 manual.
Tests level of 25 hydroxy vitamin D
Tests level of 25 hydroxy vitamin D
1,25- Dihydroxy vitamin D
To measure vitamin D levels, you take a blood test called the 25-hydroxyvitamin D test (25(OH)D test). This test assesses the concentration of 25-hydroxyvitamin D in your bloodstream, which is the primary form of vitamin D circulating in the body. It helps determine if you have sufficient vitamin D levels, are deficient, or have excess amounts.
No you are not required to fast before taking a vitamin D 25 blood test. This test determines the amount of Vitamin D a person has in their system.

The average cost of a CNA test is $25. This price can increase, depending on various factors like where you take the CNA test and in what time of the year you take the CNA test.
