Which are disadvantages?

• A. They are cost-free and perfect
• B. They guarantee 100% accuracy
• C. They replace clinical judgment
• D. Imperfection/margin of errors, cost, follow up not guaranteed, anxiety

Answer: (D)

Screening tests have clear downsides even though they help identify potential issues early. They are not perfectly accurate, so there’s always a margin of error that can lead to false positives or false negatives. This can cause anxiety for individuals and may prompt unnecessary follow-up testing or procedures. They also come with costs—financial, logistical, and resource-related—for both the screening itself and any required confirmatory tests or treatments. Additionally, follow-up isn’t guaranteed; some people won’t complete recommended steps, limiting the overall benefit. Finally, screening results don’t replace clinical judgment and must be interpreted in the broader clinical context. These factors together describe the disadvantages shown.
