analyte

 [an´ah-līt]
a substance or material determined by a chemical analysis.

an·a·lyte

(an'ă-līt),
Any material or chemical substance subjected to analysis.

analyte

By comparing analyte concentrations between serum and EDTA-treated plasma samples collected simultaneously from the same mouse, we found that arginine concentrations were consistently higher in serum than in plasma.
Concentrations of analytes in medical centers around the US and in many European countries continue to be reported in the traditional mass units, whereas SI units are routinely used in other parts of the world.
A practical procedure for converting a comparison of fluorescence radiance into a comparison of fluorescence yields is to work with the same fluorophore in the standard solution and in the analyte so that the molecular absorptivities are reasonably matched and cancel out from the comparison of fluorescence radiances.
In five years, Analyte Health's online medical service has seen its model proven out dramatically with more than 80,000 patient encounters.

Clearly the lower the analyte concentration, the lower the signal/noise ratio, it being commonly accepted that a ratio of 3 defines the LoD.
This may typically involve the use of a reference material containing a certified or known concentration of analyte, followed by replicate analyses of the sample and spiked sample (a sample to which a known amount of the analyte has been deliberately added).
A fundamental difficulty in polymer MALDI is shown by the model to be caused by the magnitude of typical MAs (or more precisely the small difference between matrix and analyte MAs).
A mass spectrometer provides the ability to calculate the concentration of analyte in a sample by comparing the response ratio of analyte to internal standard and multiplying by the known amount of internal standard added.
The analyte is usually separated from the rest of the matrix by distillation, extraction or precipitation.
Although population- and laboratory-based reference intervals are useful, clinicians frequently encounter changes in analyte values that remain within or outside the reference interval.
At least two references are included for each analyte, along with the statistical basis by which reference ranges were calculated and the population source.
