Test ID: Teicoplanin Trough
|
Teicoplanin
|
Therapeutic Drug Monitoring Assay
|
Useful For
|
The test is useful in assessing serum concentrations of Teicoplanin. Monitoring trough levels is essential to ensure therapeutic efficacy by achieving sufficient concentration.
|
Method name and description
|
Teicoplanin assay is a homogeneous particle-enhanced turbidimetric immunoassay.
|
Clinical information
|
Teicoplanin (Targocid) is a bactericidal glycopeptide antibiotic that inhibits cell wall biosynthesis in Gram-positive bacteria. It is indicated for moderate to severe infections caused by susceptible staphylococci, streptococci, and enterococci.
Due to its high plasma protein binding and exceptionally long elimination half-life (up to 150 hours), fixed dosing regimens lead to significant inter-patient variability in serum concentrations. Therapeutic drug monitoring is essential to ensure trough concentrations are sufficient for efficacy while minimizing the risk of concentration-dependent toxicity, particularly during high-dose therapy.
Results must always be interpreted in conjunction with the patient's clinical presentation and other diagnostic findings.
