The limit of detection (LOD or LoD) is the lowest signal, or the lowest corresponding quantity to be determined (or extracted) from the signal, that can be observed with a sufficient degree of confidence or statistical significance. However, the exact threshold (level of decision) used to decide when a signal significantly emerges above the continuously fluctuating background noise remains arbitrary and is a matter of policy and often of debate among scientists, statisticians an… Nettetfor 1 time siden · Analytical validation of multivariate assays, such as this MCED test, is challenging because the evaluation of test sensitivity using a single analyte-based limit of detection experiment is not directly applicable due to the fact that the MCED test aggregates information from >100,000 genomic regions to assess cancer signal status.
