If an adult without serious diseases for some reason decided to take care of his health, then he need not bother with tests for vitamin D.
Tests are needed for those who may have problems with vitamin absorption, or who have a sharp increase in vitamin requirements. These are people with obesity, osteoporosis, low blood calcium levels, diseased intestines, or old people sitting at home.
It's funny that North America is especially sensitive to unnecessary vitamin D tests.
Americans live relatively high, and the sun is not enough for them. So they drink their fortified milk even without tests.
They have taken a very tough stance on blood vitamin D testing. Both Canadians and Americans issue approximately the same official statements, in which they urge not to do unnecessary tests for either adults or children.
This is motivated by the fact that now everything is changing rapidly, and strict standards for vitamin D have not been developed.
An innocent person in such a situation can very easily be branded a lack of vitamin D, and he may not deserve it.
Personally, it seems to me that some kind of political correctness is intervening here. In the sense that everyone has the right to have their nature assigned level of vitamin D, which allows him to live normally.
Like if you are dark-skinned, then no one should hint to you that in high latitudes of the vitamin you can receive less. Everyone has the right to play hockey. Something like this... But these are my fantasies.
American pediatricians, by the way, now believe that fatty children do not need to be tested for vitamin D. If mom and dad feed them supplements, then they should better spend money on supplements than on expensive and pointless tests.
This is because obese people traditionally have low blood levels of vitamin D.
Americans also say that it would be a mistake to think that the entire population needs to have blood levels of vitamin D above 20 nanograms per milliliter.
In fact, roughly 97.5% of the population can get by at 20 nanograms per milliliter or less.
Moreover, every second needs even less than 16 nanograms per milliliter.
I suspect that you and I live geographically in approximately the same conditions and the attitude towards analyzes should be approximately the same.
