Interpretive Data
Normal peak serum concentration for meropenem is 26 µg/mL with a 500 mg IV dose or 55-62 µg/mL with a 1 g IV dose. 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.
