# 2003/422/EC: Commission Decision of 26 May 2003 approving an African swine fever diagnostic manual (Text with EEA relevance) (notified under document number C(2003) 1696), Division 2

Extent: E+W+S+N.I.

The ELISA test is the most reliable and useful test for large-scale serological studies. It is based on the detection of ASF virus antibodies bound to the viral proteins which are attached to a solid phase by addition of protein A conjugated with an enzyme that produces a visible colour reaction when it reacts with the appropriate substrate.
