Quantitation Requires Parallelism

Parallelism Between Calibrators And Dilutions Of Sample

Parallelism is a term that refers to an assay's ability to analyze patient samples in a manner that is identical to that which is used by the calibration system to convert the measured response signal into an analyte dose estimate.

 
Dilution of calibrator and serum containing specific IgE antibodies to different allergens in ImmunoCAP Systems. Dilution curves are parallel, which is a prerequisite for adequate results over the measuring range. (1)
