摘要：
Quantity quotient (QQ) reporting has been proposed by several authors to improve or support the present situation of presenting quantitative laboratory results. This proposal is based on a concept (symmetrical model) known from the intelligence quotient, which was developed to make intelligence tests comparable. In laboratory medicine, however, most measurands follow a non-symmetrical (skewed) distribution, leading to a compression of the QQ values at the lower end of the reference interval. This effect can be avoided by several alternatives. Three models considering non-symmetrical distributions are compared with the symmetrical model in the present study. The corresponding algorithms can be easily handled on the Excel platform. Graphical presentation of the QQ allows a quick overview of test results if they occur in a large number.
