Interpretive Data
Normal peak serum concentration for ticarcillin is 324 µg/mL with a 3.1 g IV dose of ticarcillin/clavulanate. Trough serum concentration is not well established.

For bioassay measurements, the presence of other antimicrobial agents may interfere with the assay. Other factors that may influence antimicrobial levels include inherent differences among patients and their underlying physical conditions as well as the dose and route of administration of the antimicrobial agent.
