Reaction of Passive HaemAgglutination (RPHA)  is based on registration  of aggregates formation of sheep erythrocytes sensibilised by antibodies or antigens in the presence of detecting antigens or antibodies. At negative result the compact residue looking as a dark dot is formed on the bottom of the platewell. At positive result the net of agglutinate is formed looking as a vague, less contrasted spot.The mostly wide spread RPHA kits in Russia are the kits for syphilis diagnostics and antibodies for different bacterial and virus antigens.“E-Lab RPHA” program functions are analogous to latex program, but specially elaborated algorithms of calculations are applied in it.
