title: [From qualification to quantification in immunoserological testings].
abstract: During the 1980's, quantifications of immunoserological testings, especially C reactive protein, rheumatoid factor and antistreptolysin O, progressed rapidly. However, marked interlaboratory differences in these quantifications have been observed. In this brief review, difficulties to satisfy requirements for good quantitative performance in immunochemical assays are discussed.
