Tramadol and Metabolite, Serum/Plasma
Clinical Use
Order TestUse
Used to determine tramadol and its active metabolite (o‑desmethyltramadol) concentrations in serum or plasma, typically for monitoring patient compliance, assessing usage within the past several days, and identifying potential overdose or toxicity.
Special Instructions
Not provided.
Limitations
Specimens collected in serum gel separator tubes may lead to falsely decreased concentrations due to drug absorption by the gel. Timing of collection (peak vs trough) affects interpretation.
