Serologic testing. Serologic testing is laboratory testing of blood specimens for biomarker confirmation of HBV or HCV infection.
Hepatitis B Risk-Factor Screening CDC has identified risk factors for becoming infected or chronically infected with HBV (see Box 5-4). As discussed in Chapter 3, improved provider awareness about risk factors is critical for ensuring that people at risk for chronic HBV infection are identified and that those at risk for becoming infected with HBV are vaccinated. Providers should review patients’ backgrounds (for example, country of birth) and discuss relevant behaviors to determine what services they need.
Figure 5-1 illustrates the pathway of services and care for people depending on their risk factors identified. People who have HIV infection or other sexually transmitted infections, men who have sex with men, injection-drug users (IDUs), and institutionalized and incarcerated persons
