Clinical Relevance of- Limit of Detection (LOD) - Limit of Quantification (LOQ) - Based Flow Cytometry Approach for Measurable Residual Disease (MRD) Assessment in Acute Myeloid Leukemia (AML)

Blood, 2020
Background: In Acute Myeloid Leukemia (AML), identification of measurable residual disease (MRD) thresholds with clinical significance is still a matter of debate. For this purpose, multiparametric flow cytometry (MFC) is extensively employed for MRD quantification, due to high sensitivity (down to 1:10-3/10-5 cells) and wide applicability (up to 90 ...

Limit of detection (LQD)/limit of quantitation (LOQ): comparison of the empirical and the statistical methods exemplified with GC-MS assays of abused drugs

Clinical Chemistry, 1994
Abstract The limit of detection (LOD) for any analytical procedure, the point at which analysis is just feasible, may be determined by a statistical approach based on measuring replicate blank (negative) samples or by an empirical approach, consisting of measuring progressively more dilute concentrations of analyte.
