What is AB?

AB definition and meaning on Health terms:
An antibody (AB), also known as an immunoglobin, is a protein produced by the body’s immune system when it detects harmful substances (called antigens). Antigens can be molecules from microorganisms (bacteria, fungi, parasites, and viruses), or chemicals (insect venom). Antibodies recognise and latch onto antigens in order to neutralise them.
