immunoglobulin

Definition

A fancy scientific term for antibodies—the Y-shaped protein soldiers your immune system deploys to tag and destroy foreign invaders like viruses and bacteria. These glycoproteins are basically your body's homeland security system, recognizing threats and coordinating defensive responses. There are five main types (IgG, IgA, IgM, IgD, IgE), each with specialized security clearances.

Example Usage

The lab results showed elevated immunoglobulin levels, indicating her immune system was working overtime fighting off something—possibly that questionable street taco.
