Reproducibility of serological titers [PDF]

Journal of Clinical Microbiology, 1980
Serologists are making increasing use of the term "reproducibility" when referring to the reliability or repeatability of serological tests. The practical use of the concept, however, has been limited by the absence of an appropriate numerical scale on which differing reproducibilities can be quantified and objectively compared.
