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 pig sIgA 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)  
1:200 Average % 92  
Range % 88-97  
1:400 Average % 94  
Range % 90-98  
1:800 Average % 87  
Range % 85-94

Could you indicate me if your kit could be valid for feces samples? Any recommendations for this type of samples?

Thanks for your inquiry.
Here advice the customer to arrange preliminary experiment if you want to detect feces sample.
Below is our sample method for your reference:
Feces Dilute samples with appropriate Sample Diluent.
This can be achieved by adding 0.1g sample to appropriate Sample Diluent.
Remove particulates by centrifugation for 10 minutes at 4000x g at 2-8°C and assay immediately.Pls let me know if you have any further questions. Thank you.
