Signal-to-noise ratio

Seen on reporting limit rationale.

Definition

The height of an analyte response relative to the baseline noise around it. It is the basis on which limits of detection and quantitation are established, and it is why a very small peak may be visible but not reportable as a number.

Related terms

Limit of detection
The lowest amount that can be reliably distinguished from noise, but not necessarily measured accurately.
Limit of quantitation
The lowest amount that can be measured with acceptable precision and accuracy.
