Definition
筛查 (shāi chá) means 'to screen' — specifically for disease, health conditions, or risk factors in a population (e.g., cancer screening). It differs from 筛选 (shāi xuǎn), which means 'to filter or screen' by sifting through candidates, data, or materials (e.g., resumes). 筛查 is medical; 筛选 is general selection.
