LINEARITY English meaning - Cambridge Dictionary

Nettet: Linearity Study • Analytical Measurement Range (AMR) – Range of analyte where results are proportional to the true concentration of analyte in the sample – Range over which the test can be performed w/o modification (e.g. no dilution) • Also called: Dynamic Range, and Reportable range • Determined in the lab by linearity experiments Nettetof the test. The laboratory must participate in the next scheduled PT event, if the Laboratory Accreditation Program requires external PT for that analyte.

Limits of linearity and detection for some drugs of abuse

NettetThe LOD varies from 0.4 to 5.0% of the DON cutoff value for each drug. The limit of quantitation (LOQ) is calculated as the LOD + 7 SD. The range for LOL is greater for drugs analyzed with deuterated internal standards compared with those using conventional internal standards. For THC acid, cocaine, PCP, and morphine, LOLs are 8 to 160-fold ... Nettet6. nov. 2024 · The analytical range or reportable range is the analyte concentration range over which the measurement is within the declared tolerances for imprecision and bias of the method. In practice, the upper limit is often set by the linearity limit of the instrument response and the lower limit corresponding to the lower limit of quantification (LoQ). NettetFlow Cytometry.
