Blood Testing

Some people, maybe those who are pomo, for some medical reason, regularly have to have blood testing done. Maybe they are on a drug that needs to be monitored closely. Maybe they have wrangled unsuccessfully with close ones over WT's deadly prohibition on blood transfusions with no results.

What if they announced to their pimi spouse or family that, as of now, these blood tests violated their conscious as the Bible speaks of blood's sacredness and that it should be poured out onto the ground. What do you think that their reaction would be?

edit: WT has no prohibition against blood testing. I'm just considering what would be the reaction of a zealous WT adherent if a person in their family, a pomo, took this position. I'm just wondering whether it might jar their thinking process a bit.
