Antibiotic Level, Piperacillin
Also known as: ML PIP
Use
This test is used to monitor the levels of the antimicrobial drug piperacillin in a patient's serum. Monitoring is essential for optimizing drug dosage, ensuring efficacy, and minimizing toxicity. The reference intervals provide guidance for interpreting drug levels relative to standard doses of piperacillin and piperacillin/tazobactam.
Special Instructions
Include the time of the last dose and a list of all antibiotics the patient has received in the past 48 hours. This information is necessary for laboratory handling and is crucial for accurate physician interpretation.
Limitations
Bioassay measurements can be interfered with by the presence of other antimicrobial agents. Other factors affecting antimicrobial levels include patient-specific variables such as differences in physical condition, and drug administration specifics including dose and route.
