JUNIOR LEVEL
What is involved in the development and validation of new diagnostic assays?
Sample answer to the question:
The development and validation of new diagnostic assays involves several steps. First, we need to identify the genetic markers that are associated with the condition we are trying to diagnose. This can be done through literature research or by conducting our own experiments. Once we have identified the markers, we design and optimize a set of primers or probes that can specifically detect them. We then perform various tests to validate the accuracy and reliability of the assay. This includes testing the assay on a large number of samples to ensure that it produces consistent results. We also compare the results of the assay with other established diagnostic methods to assess its sensitivity and specificity. Finally, we need to obtain regulatory approval before the assay can be used in clinical practice.
Here is a more solid answer:
The development and validation of new diagnostic assays is a complex process that requires a deep understanding of molecular biology and genetics. First, we must identify the specific genetic markers associated with the condition we are targeting. This can be done through literature research or by conducting our own experiments. Once we have identified the markers, we design and optimize a set of primers or probes that can specifically detect them. This involves extensive knowledge of laboratory techniques such as PCR, sequencing, and bioinformatics analysis. We then perform rigorous validation tests to ensure the accuracy and reliability of the assay. This includes testing the assay on a large number of samples to assess its sensitivity and specificity. We also compare the results of the assay with other established diagnostic methods to ensure its robustness. In addition, we need to consider regulatory requirements and obtain necessary approvals before the assay can be used in clinical practice. As a Molecular Oncologist, I have gained hands-on experience in all these aspects through my residency and fellowship training. I have conducted research projects focusing on the development and validation of new diagnostic assays for cancer.
