An automated system and process is provided for pooling samples from a multiplicity of blood or plasma donations for subsequent testing to uniquely identify any such blood or plasma donations which may be infected with a particular virus. The system includes an autosampler needle which is directly inserted into a blood or plasma sample aliquot container in order to withdraw an aliquot portion of the contents for forming a sample pool with aliquot portions of other blood or plasma samples. The autosampler comprises a tubular piercing member having a hollow interior bore and a tubular shroud surrounding the piercing member.

Automated method and system for testing blood samples

Method for obtaining highly purified transferrin from a partially purified plasma fraction containing transferrin in which the starting fraction is concentrated. Its ionic strength is reduced and then transferrin is adsorbed onto a chromatographic column. Following elution, the transferrin can be further processed through to packaging in final containers. The final purified transferrin product is sterile, at least 95% pure and is substantially free of enveloped and non-enveloped viruses.
