Therapeutic Drug Monitoring (TDM)

Drug level detection of Anti-Infectives

Personalized Drug Treatment for improved therapy success with reduced toxicity and reduced therapy costs.

Measuring and monitoring of the concentration of the drug in the blood allows continuous, individualized adjustment of the dose and prevents the drug from falling below the minimum inhibitory concentration (MIC) and thus the potential developing antibiotic resistance.

Determination of the effectiv free fraction of the drug in serum

Measurement of the total concentrations and the free and thus effective portion of the drug

Personalized dose administration taking into account age, ethnicity, metabolism and history

Detection of patient- and drug-specific variations in protein binding

Monitoring small variations can lead to significant changes in protein binding and thus the free fraction and efficacy.

lifespin has developed a method to determine the total drug concentration of an anti-infective in the blood and to digitally transmit the result within 12 hours.

Optimal medical care for critical patients remains a medical challenge due to significant individual pharmacokinetic
variability. In this context, therapeutic drug monitoring (TDM) is establishing itself as an effective way to implement personalized medicine.

It enables physicians to personalize drug therapies, precisely control dosages and thus, through personalized drug dosing, achieve optimal treatment results while minimizing the risk of concentration-dependent side effects.

Our method determines the concentration of antibiotics and antifungals, requiring only 1mL of serum for fully automated analysis.

With TDM Anti-Infectives, you can quickly achieve the optimal active ingredient level and the dose that suits your individual needs.
