A physician at a tertiary care outpatient department routinely measures random blood glucose in every patient above 40 years who attends for any complaint, and refers those with abnormal values for confirmation. This activity is best described as:

• A Mass screening
• B Opportunistic case finding ✓
• C High-risk selective screening
• D Multiphasic screening

Explanation

Opportunistic (case-finding) screening tests patients who attend health facilities for unrelated reasons, using the existing contact to screen without a dedicated programme. Mass screening covers the whole population regardless of contact with health services. High-risk screening targets defined risk groups such as family history of diabetes. Multiphasic screening means applying several tests simultaneously to a population, which is not what is described here.
