Amoxicillin

Order Code: AMOX

Test Summary

The concentration of antimicrobial agents in body fluids, most notable serum or plasma, are used to regulate therapy to ensure effective dosing (especially with oral agents where GI absorption is in question), to monitor accumulation to help minimize toxicity, and to help evaluate the pharmacokinetics of new agents. Both peak and trough levels obtained immediately after dosing or immediately prior to new dosing, respectively, may be monitored.

Reference Range

Therapeutic trough level	0.5-1 mcg/mL
Therapeutic peak level	5-15 mcg/mL

Toxic range is not established. Interpretation of results should include clinical evaluation.
This assay tests amoxicillin alone since concentrations are equivalent for amoxicillin alone or amoxicillin clavulanate levels. This assay does not detect clavulanate levels.
