Tamara Coakley is "lucky" she had this accident after 2006.
The Watch Tower banned all hemoglobin until 2006.
“Is it wrong to sustain life by administering a transfusion of blood or plasma or red cells or others of the component parts of the blood? Yes!...The prohibition includes "any blood at all." (Leviticus 3:17) - Blood, Medicine and the Law of God, 1961, pp. 13, 14“…various tonics and tablets sold by druggists show on their labels that they contain blood fractions such as hemoglobin. So it is necessary for one to be alert… if they are to keep themselves ‘without spot from the world.’—Jas. 1:27.” The Watchtower, 9/15/61, p. 557.
“Early in man’s history, our Creator ruled that humans should not eat blood. (Genesis 9:3, 4) He stated that blood represents life, which is a gift from him. Blood removed from a creature could be used only in sacrifice, such as on the altar. Otherwise, blood from a creature was to be poured on the ground, in a sense giving it back to God ...It would be right, of course, to avoid products that listed things such as blood, blood plasma, plasma, globin (or globulin) protein, or hemoglobin (or globin) iron.” The Watchtower, 10/15/92 - Questions From Readers. (Italics added)
As recently as 1998 two officials from the Watchtower Society’s “Hospital Information Services” wrote that Jehovah's Witnesses “do not accept hemoglobin which is a major part of red blood cells.... Jehovah’s Witnesses do not accept a blood substitute which uses hemoglobin taken from a human or animal source." Bailey R, Ariga T. The view of Jehovah's Witnesses on blood substitutes.

Hemoglobin was first pronounced "allowed" in the Awake! August 2006, front page title "BLOOD: Why So Valuable?"

What Are Hemoglobin-Based Oxygen Carriers?
Within each red blood cell are some 300 million hemoglobin molecules. Hemoglobin represents about one third of the volume of a mature red cell. Each molecule contains the protein globin and a pigment called heme - which includes an iron atom. When a red blood cell passes through the lungs, oxygen molecules penetrate the cell and attach themselves to hemoglobin molecules. Seconds later, the oxygen is discharged into body tissue, sustaining the life of the cells.
Some manufacturers now process hemoglobin, releasing it from human or bovine red blood cells. The extracted hemoglobin is then filtered to remove impurities, chemically modified and purified, mixed with a solution, and packaged. The end product - not yet approved for use in most lands - is called a hemoglobin-based oxygen carrier, or HBOC. Since the heme is reponsible for the rich red color of blood, a unit of HBOC looks just like a unit of red blood cells, the primary component from which it is taken.
Un like red blood cells, which must be refrigerated and discarded after a few weeks, the HBOC can be stored at room temperature and used months later. And since the cell membrane with its unique antigens is gone, severe reactions due to mismatched blood types pose no threat. However, compared with other blood fractions, the HBOC presents more challenges to conscientious Christians, who seek to obey God's law on blood. Why? As long as the HBOC is derived from blood, there are two objections that may be raised. One, the HBOC carries out the key function of a primary component of blood, the red cells. Two, hemoglobin from which the HBOC is derived, makes up a significant portion of that component. Regarding this and similar products, then, Christians face a very serious decision. They must carefully and prayerfully meditate on Bible principles concerning the sacredness of blood. With a keen desire to maintain a good relationship with Jehovah, each must be guided by his Bible-trained conscience. - Galatians 6:5.
