Publications

The aim of INSTAND as a medical-scientific professional society is to make contributions on current issues of quality assurance in medical laboratories accessible to a broad professional public. For this reason, we publish the findings from research projects and interlaboratory tests in selected peer-review journals.

We deal with topics of daily laboratory routine in our high-quality series of publications, which summarise the most important findings on methodology and diagnostics in the various fields of laboratory medicine.
