| area under curve | A statistical means of summarizing information from a series of measurements on one individual. It is frequently used in clinical pharmacology where the auc from serum levels can be interpreted as the total uptake of whatever has been administered.

| area under the curve | A measure of how much of a drug reaches the bloodstream in a set period of time, usually 24 hours. AUC is calculated by plotting drug blood concentration at various times during a 24-hour or longer period and then measuring the area under the curve between 0 and 24 hours as shown in the figure to the right.
