Routine blood tests, particularly advanced fourth-generation laboratory assays, are highly sensitive for detecting established HIV infections, but rapid or point-of-care screening tests can miss cases during early seroconversion or primary infection.
what the evidence does support
Routine blood tests detect most established HIV infections, though rapid screening tests can miss cases during early infection.
