[Proposition of a reference serum for the immunochemical assay of human serum proteins]. / Proposition d'un sérum de référence pour le dosage immunochimique des protéines du sérum humain.

Sera of healthy students (from Academy of Paris) aged between 18 and 30 years were collected with a view to routine clinical testing. 50 samples each representing the pooled sera of 400 individuals were investigated by evaluating 7 proteins for each pooled sample. Calculations of standard deviations showed that there existed a significant reproductibility of less than 2% for the population as a whole. These pooled sera representing 20 000 individual blood samples are proposed as a standard of human serum proteins.
