These are three (human) sera in which 19 proteins at three
concentrations are valued: normal, 2x normal and 3x normal.
The concentration of 13 proteins has been obtained by using
the reference serum RPPHS (Reference Preparation for Proteins
in Human Serum), certified reference material developed
jointly by the CAP (College of American Pathologists), the
BCR (Bureau Communitaire de Reference) and the IFCC (International
Federation of Clinical Chemists).
For further information about this reference material, please
consult the specifications of the RPPHS Lot #91/06 19 (CAP
designation) and CRM 470 (BCR designation).
The concentration of the remaining six proteins has been
obtained by using internal standards.
