What is the characteristic of quantitative testing?

• A. Identifies the presence of a drug only
• B. Determines the precise amount of the drug present
• C. Reports only on the medical necessity
• D. Assures drug purity levels

Answer: (B)

Quantitative testing is designed specifically to determine the precise amount of a substance present in a sample. This type of testing goes beyond merely identifying whether a drug is present or absent; it provides an exact measurement of the drug concentration. This can be crucial in clinical settings, especially for determining appropriate dosages, monitoring therapeutic levels, or assessing potential overdoses. The other options focus on different aspects. Identifying the presence of a drug refers to qualitative testing, which acknowledges whether or not a substance is detected but does not provide its concentration. Reporting on medical necessity pertains to evaluating whether a test is justified based on a patient's condition rather than measuring drug levels. Assuring drug purity levels involves assessing the quality of the drug itself, not the amount present in a sample. Thus, the emphasis of quantitative testing precisely aligns with defining the exact quantity of the drug rather than other factors.
