Whether a panel test or more-comprehensive testing methods are used, the inclusion in CF tests
of mutations that are disproportionately present in nonwhite, non-Ashkenazi Jewish ethnicities would be expected to produce better diagnostic sensitivities in these and mixed populations.
Thus, the rates of CF responding were similar during the analogue CF test
and the CF replication test.
psittaci include complement-fixation (CF) tests, modified-direct CF tests
, latex-agglutination tests, elementary-body agglutination (EBA) tests, and microimmunofluorescence tests.
The protocol for the xTAG Cystic Fibrosis 39 Kit v2 has been streamlined to make the test fast and easy to use, with less hands-on time for laboratory technicians than any other CF test
The antigen used in the CF tests
was prepared from brains of infected baby mice injected intracerebrally with vaccinia virus; infected brains were treated by the sucrose acetone extraction method (4).
Reagents for the CF test
were supplied by the Onderstepoort Veterinary Institute, South Africa, and the Centers for Disease Control and Prevention, Division of Vector-Borne Infectious Diseases, Fort Collins, Colorado.
The overall agreement of the CF test
results suggested a general robustness of these multiplex PCR-based technologies for CFTR mutation detection.

Carrier Sensitivity, NPV (a), Ethnic group status Disease percent percent Caucasian: All 1/29 1/3,300 80 99.
However, no antigenic relationship was shown by CF test
The commercial availability of the test samples described in this study provides easily accessible routine controls to monitor and evaluate respective CF test
Serologic examination of domestic animals by CF test
gave [ILLEGIBLE TEXT] results for goats (26% of 969) and sheep (28% of 421).
