The Pavia approach to clinical protein analysis.

The protein chemistry laboratory of the Pavia University Hospital is specialized in the study of monoclonal components in body fluids. It is closely connected with the research laboratory devoted to the structural and functional study of pathogenic proteins and with the Clinical Chemistry Central Laboratory. The analyses are performed on specific medical request. The analytical approach is mainly based on analysis of patient's serum and urine by high-resolution agarose gel electrophoresis and immunofixation with the possible addition of the quantification of specific proteins. The interpretation of the protein pattern and the final reporting result from the integration of the laboratory data with the clinical information. This labor-intensive approach requires skills in the performance of protein analysis and in the interpretation/referral phase, as well as close communication with the attending physician.
