Is blood transfusion permissible in Jewish belief?

Is blood transfusion permissible in Jewish belief?


There is nothing in Jewish law that would preclude a person from benefiting from a blood transfusion (or donating blood, for that matter).

Furthermore, according to Jewish belief, saving a life is one of the most important mitzvot (commandments), overriding nearly all of the others. (The exceptions are murder, certain sexual offenses, and idol-worship—we cannot transgress these even to save a life.) Therefore, if a blood transfusion is deemed medically necessary, then it is not only permissible but obligatory.

All the best,

I was almost killed by a typo. I needed a transfusion after surgery and they were taking an unnecessary amount of time and effort explaining why I needed it. It wasn't til later that I found that my religious preference had been entered as JW instead of JE.

If I recall correctly, a Jew can accept a porcine heart valve if it is needed to save his or her life. It's not the same as eating a bacon cheeseburger.

Blood transfuson
Janice, Tennessee. I agree with your comment entirely.
See my comment of 10 December. Would not withholding a life-saving transfusion (refusing to save a life) equate to murder? If so, would not those who claim that they withhold transfusion on scriptural grounds be claiming that G-d was an instigator of murder? I find it hard to find any alternative, and would like to hear clarification from those who refuse transfusions.
RM. To increase the patient's red blood cell production with Epo, or anything else, they have to be kept alive until it has time to work .
For the information of anyone facing surgery and being able to follow this path; I had an artificial hip implanted, and before the operation I gave two units of blood for an 'autologous' transfusion. If I required blood I would get my own back. If I did not require it, it would go into the blood bank for someone who did need it.
I was a blood donor for 52 years, and praise G-d that I never needed to receive any

blood transfusions
It;s a huge jump using a dietary law restricting eating the blood of an animal for restricting blood transfusions. The two aren't even comparable and its misapplication of torah

Re the above comment that murder is forbidden, even to save life. This is a more complex issue than that comment would indicate. Firstly, are 'murder' and 'killing' synonymous? Some argue that 'murder' is for personal reasons and 'killing' is for duty or humanitarian reasons. Having the ability to save life and not doing so, is the same as taking life. Seeing a person in the act of taking the life of another, having the ability to prevent that murder (even perhaps multiple murders) but only by killing the perpetrator, is not a hypothetical situation. It is an issue Police Officers and Armed Forces personnel face in the line of their duty. Having to make such a decision is unlikely for most individuals, it was forced on the passengers and crew of flight 93 on 9/11. This is a fraught question, a deeply personal one, and one which we will need to justify before G-d, but the principle is better decided after careful thought rather than in the heat and uncertainty of a stressed situation.

Blood Transfusions should be against the Torah
The Torah commands "You must not eat nothing containing blood." Leviticus 19:26. Isn't receiving a blood transfusion just as bad as eating blood? The Torah also commands "You should pour [the blood] out on the ground like water." Deuteronomy 12:16. Receiving a blood transfusion would be in violation of the scripture at Deuteronomy 12:16 which states that the blood (the source of life) should be poured into the ground like water. In addition, there are blood alternatives that can be used such as erythropoietin. Erythropietin or Epo can be used make the bone marrow produce more red blood cells. In addition, blood transfusions are not necessarily safe. In Sherwood v. Danbury Hosp., 896 A.2d 777 (Conn., 2006) a patient filed suit against a hospital claiming that she contracted HIV from from a blood transfusion given prior to surgery. The court sided with the hospital stating that the plaintiff's complaint was time barred due to the statute of limitations.

Dear Mrs. Chein,

Your fine answer does not go far enough in support of Jews (and others) donating blood. Yes, saving a life trumps all but three mitzvot. While donating blood is permitted, saving lives is required. If your spouse, parent, child or rebbe needed blood, you would rush to give, provided it did not endanger your own health. Every day someone's beloved needs blood. The fact that we do not know their name is no excuse under Jewish law. (In the 8 levels of tsedakah from Maimonides, giving when donor and recipient are anonymous to each other ranks #2 from the top. Because of medical confidentiality, this is always the case with blood.)

Thus, because the need is always here and it is safe for the donor, Jews must search out this simple way to save lives. Giving a pint of blood takes about one hour from walking in to walking out.

Shirin Bar-Sela's comment
Dear Mohammad Khan, You obviously misunderstood my comment. In no way have I ever promoted the eating of pork. I used that example, as have many Muslim and Jewish scholars, only to show that even the most important of laws can be broken to preserve a life. Taking my comment out of context is nothing more than flaming, and there was no reason other than that to feign disgust at my comment. I know nothing of witches' remedies, but I do know of health laws; my father was a scholar of both Islam and Judaism, and translated the Asaf and Rambam into English. All I said - and you repeated it - is that is it permissible to eat pork to save a life.

Shirin Bar Sela's comment
As a Muslim I found Shirin Bar Sela 's comment horrible and violation of G-d's law. There is no medical research indicating that a patient would get healed by eating pork. That would have to be remedy from witches of thousand years ago.
However under Islam pork and meat of other animals is only allowed during the outbreak of famine and war when only no other food is available. You only eat as much to sustain your life in that circumstance and not for enjoyment.

As a former Jehovah's Witness that watched her mom die from not having a blood transfusion, even though the doctor said she has a good chance of dying if she did not receive one was upsetting to me. It is not up to your conscious, if you take one you would be disfellowshipped (shunned by friends and family in the religion). They never told the members of her congregation why she really died even though it is on her death certificate, they did not acknowledge it.

blood of my blood
In England Witnesses go door to door in an attempt to convert people. Sadly this is more often than not greeted with scorn and foul derision. I, on the other hand, as a practising agnostic, invite them in and try to convert them.

Mudz, kudos to you. Porphyria - what a genius question!

Anonymous, what happened to you in those three weeks that caused you to u-turn so vehemently? It should also be noted that medicine evolved as it did because of the certain knowledge that blood is even more essential to life than water. We all know that we've only got a few days without taking in fluids but I challenge anyone to survive for just one second without blood. Why do you think keyhole surgery even exists? It will always be chosen before slicing someone open.

If god really exists then surely he would want us to use our brains for our own benefit.
