When to request this test
Patients living in regions with high prevalence or engaging in high-risk behaviors (e.g. injecting drug use, tattoos).
Interferences & limitations
- False negative results: some RDTs may fail to detect low levels of antibodies, particularly in the early stages of infection or in individuals with weakened immune responses (e.g. immunocompromised patients)
- False positive results: cross-reactivity with other antigens, autoimmune diseases
A confirmation test (ELISA or PCR) is required to diagnose an active infection
