The laboratory of the Institute of Medical Psychology is located at Bergheimer Straße 20 in Heidelberg. It is a wet laboratory with a preparation room and two storage rooms with temperature-controlled deep freezers (-20, -40 and -80 degrees Celsius), in which biomaterials (saliva and blood samples) are stored during analyses. The laboratory offers quantitative analyses of the parameters alpha-amylase, cortisol, estradiol, oxytocin, progesterone and testosterone from saliva and blood samples. For quality assurance purposes, the manufacturer's specifications of the assays as well as common quality control parameters (e.g. sensitivity, specificity or intra- and inter-assay coefficients of variation) are taken into account. Furthermore, the laboratory regularly participates in inter-laboratory ring trials. Requests to use the service can be made by employees of Heidelberg University Hospital (UK-HD) as well as by persons outside the UK-HD. Upon request, the necessary materials for sample collection are provided by IMP-UKHD. After completion of the analyses, the raw data will be processed according to standardized pipelines for further use by the respective project, and quality parameters of the measurements will be made available (see above). The costs for carrying out the analyses as well as the necessary materials are subject to a fee and are determined on the basis of a fee schedule.
