Remodelling qPCR as a tool for molecular diagnostics

by Professor Stephen Bustin   Remodelling qPCR as a tool for molecular diagnostics PCR is an incredibly powerful tool in the field of molecular diagnostics, and its current role is embedded in the clinical laboratory where it is indispensable for non-time-critical routine testing. However, point-of-care testing via lateral flow devices, as seen in the recent […]

Minimizing the number of false positives in dexamethasone suppression testing for the diagnosis of Cushing’s syndrome

Cushing’s syndrome is related to high production of cortisol and, without timely treatment, it can lead to complications such as heart attacks, strokes and type 2 diabetes. The condition can be diagnosed using a dexamethasone suppression test, which involves tracking the effects of this glucocorticoid medication on cortisol levels. Since the absorption of dexamethasone depends […]

Next-generation apo(a) standardization: why, when and how?

There is a revival of the genetically determined cardiovascular risk factor Lp(a). Yet, it is one of the most complicated clinical chemistry parameters, and up to 2-fold variation in measurement results may be observed between in vitro diagnostic tests. A next-generation reference measurement system based on mass spectrometry – and endorsed by the International Federation […]

Role of AI in optimizing the whole-slide image acquisition workflow

By Dr Maria Ada Prusicki Advances in whole-slide scanning technology enabled the automation of microscopy. Researchers can run image acquisition overnight and check the results remotely, minimizing the need for supervision and optimizing their use of time. Nonetheless, a few steps still require intense human supervision, especially for sample identification and scan area definition, where […]
