Why test for Vitamin D?

Vitamin D is a hormone responsible for promoting calcium absorption by the gastrointestinal tract. Virtually all cells in our body have vitamin D receptors, meaning they need adequate levels of vitamin D to function properly. The health risks associated with vitamin D deficiency are currently estimated to be higher than a few decades ago.

The test is easy to use and, of course, if performed correctly, provides a reliable result, comparable to a laboratory.

Vitamin D deficiency has been recognized as a global epidemic. Severe vitamin D deficiency is causally linked to serious diseases such as osteoporosis, osteomalacia and muscle weakness and associated with multiple sclerosis, cardiovascular disease, pregnancy complications, diabetes, depression, increased mortality, autoimmune diseases, influenza, infectious diseases, Alzheimer’s, obesity and an increased risk of various forms of cancer (see figure above, copyright Dr Jos Wielders, September 2016).

Therefore, determining (25-OH) vitamin D levels can be seen as a medically necessary screening test, not only to promote bone health, but to improve health in general. In the Netherlands, measuring vitamin D is recommended for the risk groups of the elderly and immigrants, especially in combination with dark skin and a lifestyle with little sun exposure.

The two most abundant forms of vitamin D in the human body are vitamin D2 and vitamin D3. Vitamin D3 is produced in human skin under exposure to ultraviolet light (sunlight) or absorbed from animal foods. D2  vitamin is only absorbed from plant foods.

Reliability

The vitamin D self-test has high reliability values in terms of sensitivity and specificity. In addition, the test is CE-certified.

The sensitivity of a medical test is the percentage of correct positive results in sick people.

Sensitivity = 94%

The specificity of a medical test is the percentage of correct negative test results in non-sick people.

Specificity = 94%

Instructions for use:

  1. Open the sealed bag and remove the test cassette. Place it face up on a clean, dry, and flat surface.
  2. Massage your fingertip and clean it with the alcohol wipe. Now let the arm hang down for a few minutes to improve blood flow to the fingers.
  3. Press the automatic lancing device with the round opening firmly against the clean fingertip and wait for a drop of blood to appear.
  4. Take the transfer pipette and hold it horizontally against the drop of blood so that the transfer pipette fills.
  5. Add two drops of blood to the test cassette (S).
  6. Add 2 drops of buffer to the test cassette (S).
  7. Read the result 10-15 minutes after adding it.

For a full result, please read the instruction manual before use.

Wat is vitamine D?

Vitamin D is a hormone responsible for promoting calcium absorption by the gastrointestinal tract.

In the Netherlands, measuring vitamin D is recommended for the risk groups of the elderly and immigrants, especially in combination with dark skin and a lifestyle with little sun exposure.

Guidelines

Many guidelines for determining vitamin D deficiency have been published by national public health organizations, without leading to internationally accepted recommendations on lower limits. This is partly due to the basic principles (only considering bone pathology or looking more broadly at multiple health effects) and partly due to the requirements imposed on the design and quality of the research accepted as evidence. International literature suggests the following  intervals for classification of vitamin D status:

25-OH VITAMIN D LEVEL REFERENCE AREA (NMOL/L)
Deficient 0-25
Insufficient 25-75
Sufficient 75-250
(Possibly) toxic >250

In the Netherlands, the Health Council (advice Evaluation of the dietary reference intakes for vitamin D) recommends a lower limit of 30 nmol/l up to age 70 and above 50 nmol/l. Laboratories and a large proportion of healthcare providers prefer to use 50 nmol/l for all ages as a lower limit and a target value of 75 nmol/l or higher.
