The analytical process of determining drug concentration typically involves a systematic approach that includes both screening and measurement. Screening refers to the initial phase where a sample is analyzed to identify the presence of specific substances, often utilizing techniques such as immunoassays or initial chromatographic separations. Once a drug is confirmed to be present, the measurement phase quantifies the concentration of that drug using more precise methods, such as high-performance liquid chromatography (HPLC) or mass spectrometry. This two-step process ensures both the identification of the drug and accurate quantification, which is essential for understanding its efficacy and safety in a clinical context.

Other approaches, such as visual inspection or qualitative analysis alone, do not provide the necessary quantitative data to determine drug concentration accurately. Similarly, microscopic examination is more focused on structural analysis rather than quantitative measurements, making it unsuitable for this specific purpose.
