The company says the retail value of that kit is $400, but sells it for $300 online.
Per manufacturer's specifications, the sensitivity, specificity, positive predictive value, and negative predictive value of this kit are 96%, 97%, 90%, and 99%, respectively).
The prognostic value of the c-kit expression was demonstrated by a univariate analysis, but not by a multivariate analysis.
For the technical comparison, the cut-off value of the prototype kits was based on the mean ± three standard deviations of 12 healthy blood donors.
On the other hand, the prognostic value of the c-kit expression was demonstrated based on multivariate analyses for nueroblastomas (Krams et al, 2004).
Therefore, the aim of the present study was to evaluate the relationship between the c-kit expression and the clinicopathological factors in invasive ductal carcinoma of the breast, and the prognostic value of the c-kit expression in breast cancer was also evaluated using univariate and multivariate analyses.
There have, however, so far been few studies on the relationship between the c-kit expression of breast cancer and clinicolpathological factor such as lymph node metastasis and the proliferative activity, and the prognostic value of the c-kit expression in breast cancer has not yet been evaluated.
The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the kit were 77.1%, 88.0%, 73.6%, 89.8%, and 84.7%, respectively.
Serum samples with BAFF levels exceeding the maximum value of the standard curve for the kit were diluted and re-assayed.
