WebOnce the assay quantitation accuracy is validated based on acceptable recovery at multiple spike levels, routine quantitation can be performed by testing replicates (e.g. duplicates or triplicates) of the sample and its appropriate buffer control and calculating the difference. Webthe routine analysis. This is a pharmacopoeia requirement. Spike recovery can be used for investigational purposes and provides a health check for the manufacturing process. Typically, if something occurs in the manufacturing process it will be observed in the spike recovery and past data will validate your assumptions.

WebAlso known as “Spike and Recovery”. Your method should be able to quantitatively recover a known amount of standard or API spiked into your placebo Typical Assay Data: Spiking is typically performed at 80% (n=3), 100% (n=3) and 120% (n=3) of your drug’s label claim Typical Assay Acceptance Criteria: % Recovery is within 98.0% to WebFeb 24, 2024 · Spike recovery is a good method to determine if process-specific buffers have a detrimental effect on the assay. Using the assay standard for this is preferred as a control — however, the best results can be obtained by also using HCP from the customer’s specific processes that has been measured by an orthogonal method (e.g., mock cell line ...
