Confirm paternal half-sister

[ShawnN]

Can FF test be used to confirm my paternal half sister? After doing a bit of reading it mentions females getting x from both parents but males only getting x from their mother so was wondering if the Autosomal test somehow could be used to confirm my half sister and I are actually related.

Yes it can

And it's not solely a matter of the X chromosome. The total amount of DNA you share will prove it. They will assign you a relationship of "Half Siblings, Grandparent/ Grandchild, Aunt/ Niece" if you are half-siblings, because all of them share roughly the same amount of DNA. Double cousins also fall in that category, though they don't state that.
