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.

Please include time of last dose, and list of all antibiotics that the patient is receiving or has received in the past 48 hours.  This information is important for laboratory handling and essential for subsequent physician interpretation of results.
