Each antibody is specifically produced by the immune system to match an antigen after cells in the immune system come into contact with i This minimizes non-specific binding that leads to false positives and high background noise. An antibody is defined as “an immunoglobulin capable of specific combination with the antigen that caused its production in a susceptible animal.” Antibodies are produced in response to the invasion of foreign molecules in the body. It’s right and their production comes about as a result of medications for instance patients administered with alpha-methyl dopa develop haemolytic anaemia due to the production of RBC auto-antibodies, but it’s also seen that the anemia resolves on stopping the use of this drug.
