The in-house coefficient of variation of the BMD measurements ranged from 0.5 1.4%.
The assay has been validated in-house, showing a coefficient of variation of less than 8%% over time.
We test our concept by infiltrating both top and bottom surfaces of a strong class of zirconia ceramic with an in-house prepared glass of similar coefficient of thermal expansion and Poisson's ratio to zirconia, producing a controlled modulus gradient at the surface without significant long-range residual stresses.
Correlation between the anti- Toxoplasma IIF commercial test and in-house IIF was excellent (kappa coefficient = 0.98) and allowed us to compare the antibody titers against both parasites.
(1) In one experiment, plasma and alveolar PTX3 was assayed with a specific enzyme-linked immunosorbent assay (ELISA) kit developed in-house (intra- and interassay coefficients of variation <10%, sensitivity of 0.1 ng/ml, assay dynamic range from 75 pg/ml to 2.4 ng/ml).
This has a sensitivity of 0.16 ng/ml (1.1 pmol/L) and in-house intra- and inter-assay coefficient of variation of <6%.
The Microarray Quality Control Consortium MAQCC) study highlighted once again that in-house microarrays generate a much higher coefficient of variation for expression signals compared to commercial products [ 6].
To quantify the spatial similarity between the sighted and blind group maps, we computed a concordance correlation coefficient (Lin, 1989 ) using in-house software written in MATLAB (MathWorks).
In order to visualize the parameter estimates related to the parametric regressions described above, regression coefficients were extracted using in-house Matlab (The MathWorks, Inc).
Serum IGFBP1 levels were measured by an in-house radioimmunoassay with intra-assay and interassay coefficients of variation of 3 and 10%, respectively.
Numerically obtained results from ANSYS Fluent 15.0 were compared with in-house experimental results to determine the heat transfer coefficient from the walls of the heat sink.
