Which term describes testing to keep drug levels within a target range?

• A. Therapeutic blood monitoring
• B. Urine drug screen
• C. Pharmacokinetic analysis
• D. Toxicology screen

Answer: (A)

Therapeutic drug monitoring focuses on keeping drug levels in the blood within a target range to balance effectiveness with safety. This approach is used for medicines that have a narrow therapeutic index, where small changes in dose or how the body handles the drug can shift from a positive effect to toxicity. By measuring the drug concentration at appropriate times and adjusting the dose accordingly, clinicians aim to maintain levels in the desired window. Urine drug screens detect whether a drug or its metabolites are present, not the exact blood concentration needed to guide dosing. Pharmacokinetic analysis studies how the body absorbs, distributes, metabolizes, and eliminates a drug, often for research or optimization, rather than routine level Maintenance. Toxicology screens look for toxins or a broad range of drugs to assess exposure or poisoning, not to regulate therapeutic levels.
