Hi Experts,
I encountered difficulties during the validation of a mouse serum pharmacokinetic (PK) assay. While the recovery and %CV were consistently good for standards, I observed significant variability in the recovery of the lower limit of quantification (LLOQ) in the quality control (QC) set during inter-precision validation.
Could you please give me some suggestion how to solve this problem?
is there something wrong with my ELISA assay which I donot know and is important for QC's recovery?
Appreciate your help in advance!
