The phrase "as negative specificity" is correct and usable in written English.
It can be used in contexts discussing the precision or clarity of negative statements or characteristics.
Example: "The study highlighted the importance of as negative specificity in understanding the limitations of the research findings."
Alternatives: "as negative precision" or "as negative clarity".
Of 53 non-TB samples, Xpert MTB/RIF identified 51 as negative specificity: 96.2% (Tables 1 and 2).
Conversely, if we reported every image as negative, specificity would be perfect but we would never diagnose any abnormality.
According to the chosen threshold, 24 out of 27 normal controls were classified as negative (specificity = 88.9%), while 87 out of 98 EOCs were classified as positive (sensitivity = 88.8%).
However, this also allowed us to use GFP as a negative specificity control and, as expected, UBC12 did not coimmunoprecipitate with GFP.
p53−/− hESCs and fibroblasts were used as negative controls for specificity of immunoprecipitation. (D) The interaction between p53 and Mdm2 in p53+/− and K8R cells by co-immunoprecipitation. p53 was immunoprecipitated from p53+/− and K8R cells, and the levels of p53 and Mdm2 in the immunoprecipitate were determined by Western blotting.
Non-immune goat, rabbit and chicken IgGs (Insight Biotechnology Ltd) served as negative controls for specificity of primary antibodies.
Using the RAD cut off criteria for disability, 63 (62.4%) participants recruited as cases were identified to have disability (true positives, sensitivity) and 82 (81.2%) controls were identified as not having disability (true negatives, specificity) in Fiji, indicating acceptable sensitivity and very good specificity in detecting disability.
The kinase-dead variant K1906M served as negative control to confirm specificity of the observed signals.
Media collected from 293T cells transfected with wild type mouse proinsulin was used as negative control for radioimmunoassay specificity.
In the laboratory, these behaviors can serve as negative controls for the specificity of tectum manipulations.
Out of the remaining 1457 lesions, 501 were diagnosed as negative, yielding an observed specificity of 34·4%.
