You have seen how to use pandas to filter and summarize lab results—essential skills for extracting actionable insights from clinical data. Filtering allows you to isolate records that meet specific criteria, such as abnormal values, while aggregation methods help you quickly summarize counts or averages across groups. In real-world pharmacy settings, these techniques enable you to monitor patient safety and flag potential issues promptly.
