Sensitivity specificity curves
Webis the sensitivity of test 2 (i.e. the test performed on January 25). The total averaged sensitivity σ+=0.9044 is obtained by averaging the sensitivity of repeated testing when considering uniform distribution of exposure times. Specificity Specificity does not depend on viral load and is assumed to be the same on January 22 and on January 25. Web9 Mar 2024 · The ASIMBs showed high sensitivity, specificity and good biocompatibility to the model CTCs and low nonspecific adsorption to the negative cells (∼93% for MCF-7 cells and 17% for Jurkat cells). ... and the standard fluorescence emission curve of goat anti-mouse IgG-FITC antibody was acquired.
