From: Screening is not always healthy: an ethical analysis of health screening packages in Singapore
Category^ | Example |
---|---|
Category 1—suitable for population level screening There is good evidence that test is effective and cost efficient for population screening. A caveat is that the individual must fit the age and sex profile of the target population for the test to be considered appropriate | Fasting lipids in individuals aged 40 years and above to screen for hyperlipidaemia |
Category 2—suitable for individual level action Test may be useful for high-risk populations or its cost effectiveness has not been evaluated or is unfavourable | Alpha-fetoprotein in hepatitis B carriers to screen for liver cancer |
Category 3—not recommended There is insufficient evidence or the net harms outweigh benefits for use as screening test | Serum uric acid to screen for gout |
