Can A Blood Transfusion Give You New Allergies
Very Unlikely, but..: ...Not impossible. First, there is the possibility of a reaction to the transfused blood itself, in spite of type and crossmatch; second, a very small amount of serum remains with packed red cells (the most usually transfused part of blood) and it contains the donor's ige, the allergic immunoglobulin, which may contribute to a mild, temporary, and very rare new allergy. ...Read moreSee 1 more doctor answer
Allergies occur when your immune system is triggered by envirionmental factors it should ignore--for example, pollen in the air, or dander on a cat or dog--and creates cells to fight against them. An allergic reaction typically causes itching, congestion, or drainage, and ...Read more
Can you tell me if O- blood can be used in a transfusion to a person of any blood type. is there any medical benefit to using a matching blood type over o-?
Can you tell me if a b- blood type could be used for someone with o+ blood type to have a blood transfusion?
No: Each person has two components to blood type (one each from mother & father). To be "O," both must be O (OO). To be type B, could be BO, BB, OB. Type O(-) ideally is the "universal donor," as cells lack any major antigens. O could be given to B,but Type B has antigens that would react in a person w/type O blood. ...Read more
Please answer! what would happen if you receive a small blood transfusion from a person not your blood type?
Depends: If the transfusion is with compatible blood, as expected, then there should be no hemolysis in the patient. Usually blood type "O" is considered the universal donor because is compatible with all other types (A, B, and AB). If the patient is type "O" then the only blood type compatible is "O". ...Read more
What can happen if you need a blood transfusion due to low platelets during cancer and you refuse to have the transfusion?
What could happen if you receive a small blood transfusion from a person who is not your blood type?
No.: It's very unlikely. First the donor, who appears completely healthy, would have to have cancer cells in their blood, such as with leukemia, and not know it. The donated unit must pass the all the lab tests. Finally the donor and the recipient would have to be a tissue match, not just have compatible blood. The odds there are less than 1 in 10, 000 if the blood is not from a relative. ...Read more
No: There may be extremly rare exceptions but a variety of reasons prevent this from happening including the careful screening of blood, the difference in the make up of individuals, the refrigerated storage of blood, use of leuko depletion to removed white blood cells, etc. ...Read moreSee 1 more doctor answer
Typical Reaction: Just like dr. Machtinger stated, blood mismatches can cause itch and rash. But the simple infusion of a "foreign" blood product can stimulate your mast cells to release histamine causing the itch and rash. Unless something more serious happens, maybe they could slow down the infusion rate and/or pre-treat you with an antihistamine to prevent this reaction in the future. ...Read moreSee 2 more doctor answers
Would mitral regurgitation cuase someone to have a decreased red blood count, and would a blood transfusion help the case?
It could: Severe mr with turbulent flow can cause hemolysis of rbcs. Although a transfusion will top you off it won't solve the underlying problem. ...Read more
After a blood test, if your blood is completey disease free, can they give it to someone else for transfusions?
Not sufficient : Amount. The amount of blood collected for blood tests is 5-10 ml and even if it were the best blood ever, it would be too little for transfusion. For transfusion about 350-500 ml is collected and tested for a number of parameters before transfusion. ...Read more
Can a blood transfusion from a healthy patient help a patient with sever rheumatoid arthritis? And is anyone trying to do blood transfusions for this?
Highly unlikely.: This is unlikely to help a rheumatoid arthritis patient, unless they also have severe anemia/blood loss. Rheumatoid arthritis is a disease that is characterized by inflammation of joints due to many immunologically mediated processes that transfusion would likely aggravate rather than alleviate. Plasmapheresis might help this as it would remove things like rheumatoid factor but is not done. ...Read more
If you receive a blood product like ivig (intravenous immunoglobulin) can you still be an organ donor later on?
I want to go get a blood test for allergies. Will this assess for all types of allergens? Will it tell if I'm allergic to food dyes?
Uncertain: Every single test needs be interpreted with the history and physical findings in context. Food dye allergy. other than to red carmine dye, is very rare if non-existent although it was in vogue over 40 years ago. ...Read more
Immune reaction: The body identifies the foreign red cells and launches attack to destroy "invaders." The cells are destroyed by immune system, proteins/cell components get filtered out by kidneys, but can overload and cause kidney injury--> failure and shock. In sick patient, can be fatal (=why crossmatch process is so intensive). ...Read more
