The selection of a large number of biosamples can be tedious and time-consuming. Central BioHub offers pre-selected and accurately composed sets of biospecimens as panels that save a lot of time and money. The panels are theme-specific and available in different sizes with the stock growing steadily. They are ideal for testing diagnostic systems for interfering substances. Every diagnostic device has to be tested for potential interfering factors during development. For this essential step in assay validation, we have put together ideally composed collections of biospecimens: - Interfering Substances Panel - Sepsis Panel - Rheumatology Panel - Thyroid Diseases Panel - Obesity Panel - Pregnancy Panel - Diabetes Panel - Gerontology Panel - Oestrogen Panel Besides the interference panels, biospecimen collections of COVID-19 patients in different sizes tested positive or negative available.
