The free test will correctly tell you (96% of the time) that you are deficient – which appears to be somewhere between 10 and 20 nanograms of vitamin D
Vitamin D testing is only needed to confirm that you are getting enough vitamin D (from sun/uv/supplements).
The amount of vitamin D from sun/uv/supplements varies almost 4 to 1 between similar individuals (same age, weight, skin color, etc).
It is extremely rare to have too much vitamin D, so testing is not used to check for toxicity.
