Detection RANGE

  • 0.313-20ng/mL The standard curve concentrations used for the ELISA’s were 20ng/mL, 10ng/mL, 5ng/mL, 2.5ng/mL, 1.25ng/mL, 0.625ng/mL, 0.313ng/mL

Sensitivity : 

  • The minimum detectable dose of this kit is typically less than 0.116ng/mL.
Specificity :
  • This assay has high sensitivity and excellent specificity for detection of Cytokeratin Fragment Antigen 21-1 (CYFRA21-1). 
  • No significant cross-reactivity or interference between Cytokeratin Fragment Antigen 21-1 (CYFRA21-1) and analogues was observed.
Precision :
  • Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Cytokeratin Fragment Antigen 21-1 (CYFRA21-1) were tested 20 times on one plate, respectively. 
  • Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Cytokeratin Fragment Antigen 21-1 (CYFRA21-1) were tested on 3 different plates, 8 replicates in each plate. 
  • CV(%) = SD/meanX100 
  • Intra-Assay: CV<10% 
  • Inter-Assay: CV<12%
                                                            Stability :
                                                            • The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. 
                                                            • To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.
