Definition

A milliequivalent (mEq) is a unit of measurement used to express the concentration of electrolytes in a solution. It represents one-thousandth of an equivalent. This unit is commonly used in medicine to measure the amount of electrolytes like sodium, potassium, and chloride in blood and other bodily fluids. It helps doctors assess electrolyte balance, which is crucial for proper bodily function. Think of it as a tiny unit for measuring the 'active' part of a substance.

Etymology

'Milli-' is a prefix meaning one-thousandth. 'Equivalent' refers to the amount of a substance that will react with or replace a specific amount of another substance. The term 'milliequivalent' combines these concepts to express very small quantities of reactive substances.
