If both your parents did a DNA test with the same company, and you are their child and not the result of a liaison with the milkman, you are 100% screwed.
If you are the product of a liaison with the milkman and the milkman didn’t do a DNA test with the same company, you’re 50% screwed.
If you were adopted, then there will be no impact from the DNA test, but if your parents didn’t tell you, they’re 100% screwed. (Assuming that your birth parents didn’t have a DNA test.)
In other words, there’s a non-zero chance that you’re screwed.
