COVID-19 diagnostics: which test should you choose?
RT-PCR, antigen and antibody testing; each has its niche and each has a flaw. But what are the key differences between each of these tests and what are the key things to consider when selecting the appropriate COVID-19 diagnostic for you?
In this podcast, supported by Zymo Research, I speak to Senior Scientist in assay development Paolo Piatti in order to answer this question. Whether you are a concerned citizen looking for the best test to take to inform your behavior, or a researcher aiming to understand which testing systems you need to set up in your lab – this episode should have the answers for you.
In addition to these key points, Paolo addresses the importance of testing during the rollout of vaccine programs and issues of false negatives in diagnostics, examining what, if anything, can be done to improve the accuracy of testing programs.

Skills-based teaching and microcredentialing in STEM
54:22|This episode of Talking Technique deviates slightly from specific lab technologies to instead discuss techniques and methods we use for teaching and testing life sciences.To do this, I’m speaking to two pioneers of unconventional teaching and testing approaches to STEM education. Angela Consani is the Co-Founder and CEO of the Bioscience Core Skills Institute (KS, USA). This skills-first microcredential program provides certification for lab skills in techniques, safety and quality control, using performance-based practical testing.
