This is how they are supposed to deal with it , according to p111 of the new "Shephering The Flock" Book . I noted the words unrepentantly (well, you could argue that you would have been repentant if they had asked you.)..and willingly taking it...In your case you did not know about it.
"Willingly and unrepentantIy taking blood.
If someone willingly takes blood, perhaps because
of being under extreme pressure, the committee
should obtain the facts and determine
the individual's attitude. If he is repentant, the
committee would provide spiritual assistance in
the spirit of Galatians 6:1 and Jude 22,23. Since
he is spiritually weak, he would not qualify for
special privileges for a period of time, and it may
be necessary to remove certain basic privileges.
Depending on the circumstances. the committee
may also need to arrange for an announcement
to the congregation: "The elders have
handled a matter having to do with [name
of person]. You will be glad to know that
spiritual shepherds are endeavoring to render
assistance." On the other hand, if the elders
on the committee determine that he is
unrepentant, they should announce his disassociation."
BTW..Get well soon Oompa, sorry to hear about your accident but I am pleased that you are still with us
