Measurement Competitive
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 sLDL 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)  
1:100 Average % 95  
Range % 92-103  
1:200 Average % 92  
Range % 86-96  
1:400 Average % 104  
Range % 97-107  
1:800 Average % 84  
Range % 80-88  
The recovery of human sLDL 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.

What kind of dsLDL does the kit measure? (LDL-cholesterol? LDL-ApoB…. Etc?)
How does the kit differentiate de sdLDL from other LDL?

Thanks for your inquiry.
This kit specifically use the sLDL raw material and detects the total sLDL(including the free SLDL or in combination with other proteins).
sLDL is the small dense Low-Density Lipoprotein,sd LDL or sLDL, which has much smaller grains and lower densities.
While those larger grains and lower densities LDL called large LDL.
You also can check more detailed informaiton on sLDL from this link: Pls let me know if you have any further questions. Thank you.
