Abstract

A disposable apparatus for use in blood testing includes a housing (21) having integrated means (41) for receiving a blood sample, a plurality of receptacles (28-33) for diluent and diluted sample, and a plurality of channels (34-39). Depressions are formed in a surface (27) of the housing to form the receptacles (28-33) and the channels. A diaphragm (40) seals the receptacles and the channels relative to said surface (27). When a pressure variation is applied to a portion of the diaphragm sealing a receptacle, liquid is caused to be displaced to or from that receptacle.
