Antibodies in blood causes
What substance causes the body to produce antibodies?
An antibody is a protein produced by the body's immune system in response to antigens, which are harmful substances. Antigens include bacteria, fungi, parasites, viruses, chemicals, and other substances the immune system identifies as foreign.
What does having antibodies in your blood mean?
Antibodies are proteins produced by your body to help protect you against infections. They can, however, mistakenly attack your own tissues, causing illness. The consequence is described as an autoimmune disease, and some thyroid conditions are caused by this immune system dysfunction.
Are antibodies in blood from transfusions harmful?
Patients often develop antibodies to transfused red blood cells making it more difficult to find a match if future transfusions are needed. Transfused blood also has a suppressive effect on the immune system, which increases the risk of infections, including pneumonia and sepsis, he says. Frank also cites a study showing a 42 percent increased ...
Why do antibodies attack red blood cells?
An antibody binds to red blood cells at low temperatures and causes destruction of red blood cells within arteries and veins after warming. It occurs most often after a viral illness or in otherwise healthy people, although it occurs in some people with syphilis.

Antibodies are proteins that are found in your plasma (the liquid portion of your blood). Your cells make antibodies in response to antigens on cells that are different from your own and foreign targets such as viruses and bacteria. Antibodies play a key role in the immune system.

The antibodies are specific to one binding site on one protein antigen and so can target a specific chemical or specific cells in the body. They are produced by stimulating mouse white blood cells to make a specific antibody. The white blood cells are combined with a special kind of tumour cell to make a cell called a hybridoma cell.
