Is it a new thing that there is no mention of blood fractions, or was that taken off a while back? When I was in, there was section on the card about blood fractions and you marked which ones you were willing to accept. It does't look like it's even addressed on the card now. It looks like the card is just saying no blood in any shape or form.
I know it says "no major components" but without any further detail, it puts your decision about fractions in a pretty grey area. Without it being spelled out, what prevents your family from stopping doctors from even administering blood fractions or drugs made from blood fractions?
