Likewise, it is not impermissible for Jehovah's Witnesses to use such products if made from any of the four components of blood provided (1) the product of interest should be a "nutrient" derived from one of these blood components and (2) they should choose to do so, for such blood fractions are no longer blood, so that would not be reusing it in their own bodies, and they may conscientiously choose to accept or reject such nutrients (fractions) in connection with the medical treatment they receive.

Are we to consider the injection of serums such as diphtheria toxin antitoxin and blood fractions such as gamma globulin into the blood stream, for the purpose of building up resistance to disease by means of antibodies, the same as the drinking of blood or the taking of blood or blood plasma by means of transfusion?
No, it does not seem necessary that we put the two in the same category, although we have done so in times past. Each time the prohibition of blood is mentioned in the Scriptures it is in connection with taking it as food, and so it is as a nutrient that we are concerned with in its being forbidden....
The injection of antibodies into the blood in a vehicle of blood serum or the use of blood fractions to create such antibodies is not the same as taking blood, either by mouth or by transfusion, as a nutrient to build up the body’s vital forces.
While God did not intend for man to contaminate his blood stream by vaccines, serums or blood fractions,
doing so does not seem to be included in God’s expressed will forbidding blood as food. It would therefore be a matter of individual judgment whether one accepted such types of medication or not."
DJ is a blood fraction food/nutrient or not? In your first post that I quoted you indicate that it is?
