The implementation of risk-based screening can vary, but generally involves the following steps:
1. Identification of Risk Factors: Risk factors such as age, genetics, lifestyle, and pre-existing conditions are identified through epidemiological studies. 2. Risk Stratification: The population is stratified into different risk categories based on the identified factors. 3. Screening Protocols: Specific screening protocols are developed for each risk category, which may include different testing methods or frequencies.
