analytic sensitivity

an·a·lyt·i·c sen·si·tiv·i·ty

1. the threshold of detection;
2. the degree of response to a change in concentration of analyte being measured in an assay.

analytical sensitivity

The concentration at which the mean response is statistically beyond the noise limits of the signal at zero concentration. Analytical sensitivity is the ability of a test to detect a target analyte (e.g., an antibody or antigen), which is usually expressed as the minimum detectable concentration of the analyte. In practice, the way in which analytic sensitivity is calculated varies according to the lab, with differing replicates and matrices.

The ability of a test to detect a particular analyte or substance or a minimal change in the concentration of the substance.
