RAN 4060/109 Abstract There is disclosed an improved process for the pre- treatment of a sample of serum which is to be used in the determination of carcinoembryonic antigen. The improved pro- cess, in essence, comprises negating potentially interfering substances in the sample by diluting the sample with water and heating to a temperature below that which, at the ionic strength and pH of the sample, would cause coagulation of the proteins present and carrying out an immunoassay for carcinoembryonic antigen on said sample.
