The principle of the blood vitamin D reading in this (and probably other home tests) is to compare the intensity of the coloured bar with the scale on the printed card provided. This is very imprecise, so the result is very, very approximate.

It's fine for an indicative result and it makes sense
I didn't want to prick my finger, but still better than a vein .

This test is at most just an indication of whether you are already overdosing on vitamin D, because reading the color from the test strip and comparing it to the printed scale to see if it is a deficient, insufficient, sufficient vitamin D result is quite difficult. When we took this test as a family, it revealed my wife and I as deficient and the blood tests after that over the holidays revealed that my wife was deficient and I was normal.
more affordable than going somewhere for blood, but just to check for vitamin D overdose.
inaccurate evaluation by the user, because comparing where a given colour falls and where it doesn't is pretty shitty
