Which QC concept involves creating a replicate of the same sample through the entire analytical process?

Creating a duplicate of the same sample and sending it through the entire analytical workflow tests how repeatable the method is under real running conditions. By splitting one sample into two or more aliquots and analyzing them separately, you capture small variations in sample handling, instrument performance, and measurement. If the results are close within predefined limits, you gain confidence in the method’s precision; if they diverge, it points to random errors or consistency issues that need addressing. This approach is different from spikes, which add a known amount of analyte to test recovery; blanks, which check for contamination or background signal; and calibrators, which establish the standard curve for quantitation. So, duplicating the sample through the full process directly assesses intra-assay precision and reliability.
