Assay Principle quantitative
Measurement Sandwich
Intra-assay Precision (Precision within an assay): CV%<8%      
Three samples of known concentration were tested twenty times on one plate to assess.  
Inter-assay Precision (Precision between assays): CV%<10%      
Three samples of known concentration were tested in twenty assays to assess.    
To assess the linearity of the assay, samples were spiked with high concentrations of human IgA in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
  Sample Serum(n=4)  
1:10000 Average % 89  
Range % 85-94  
1:20000 Average % 90  
Range % 86-97  
1:40000 Average % 96  
Range % 90-103  
1:80000 Average % 89  
Range % 86-93  
The recovery of human IgA spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.
Sample Type Average % Recovery Range  
Serum (n=5) 91 89-94  
EDTA plasma (n=4) 92 88-97
