Limit of quantification definition

Limit of quantification or “LOQ” means the minimum levels, concentrations, or quantities of a target variable, for example, an analyte that can be reported by a laboratory with a specified degree of confidence.

Limit of quantification means a concentration of an analyte at which one can state with a degree of confidence, using the most sensitive analytical test method approved by EPA, for that sample matrix that an analyte is present at a specific concentration in the sample tested.

Limit of quantification means a stated multiple of the limit of detection at a concentration of the determinand that can reasonably be determined with an acceptable level of accuracy and precision. The limit of quantification can be calculated using an appropriate standard or sample, and may be obtained from the lowest calibration point on the calibration curve, excluding the blank;

Related to Limit of quantification

  • Limit of Quantitation or “LOQ” means a measurement of the concentration of a contaminant obtained by using a specified laboratory procedure calibrated at a specified concentration above the method detection level. It is considered the lowest concentration at which a particular contaminant can be quantitatively measured using a specified laboratory procedure for monitoring of the contaminant. This term is also sometimes called limit of quantification or quantification level.
