The present invention provides a test strip (10) for detecting, in a sample from a human subject, the presence of an antigenic substance which comprises a solid support (11), the antigenic substance bound to a first discrete area (14) on the solid support (11), an anti-human antibody bound to a second discrete area (15) on the solid support (11) as a positive control, and an antibody directed against an antigen which does not naturally occur in human subjects bound to a third discrete area (12) on the solid support (11) as a negative control. The invention additionally provides a test strip (21) for detecting, in a sample from a human subject, the presence of an antigenic substance which comprises a solid support (11), an antibody-based reagent directed against the antigenic substance in an immune complex and native human antibody thereto bound to a first discrete area (24) on the solid support (11), an anti-human antibody bound to a second discrete area (15) on the solid support (11) as a positive control, and an antibody directed against an antigen which does not naturally occur in human subjects bound to a third discrete area (12) on the solid support (11) as a negative control. The invention also provides for a method for detecting in a sample from a human subject the presence of an antigenic substance using the aforementioned test strips. |
