The phrase "as primary test" is not correct in written English.
It may be intended to refer to a main or initial test in a specific context, but it lacks clarity and grammatical structure.
Example: "We will use the results from the initial phase as primary test data for our analysis."
Alternatives: "as the main test" or "as the initial test".
Despite its limited sensitivity [ 1], the conventional cytology test has long been used as primary test method.
The impact of replacing CC by LBC as primary test method depends on the type of LBC test used.
Using SurePath versus conventional cytology as primary test method resulted in a 12%% increase in the rate of primary smears classified as >BMD.
Our results indicate that the widespread use of SurePath as primary test method has led to an increased probability to detect both CIN I and CIN II+ lesions.
The widespread use of ThinPrep as primary test method did not lead to changes in CIN II+ detection rates, although cervical cancer detection was nonsignificantly lower.
Economic issues of cost-effectiveness of IHC or ISH as primary test have been the issue of several previous studies and are still debated [ 10, 11].
We are not aware of any similar studies on systematical analysis of HER2 positivity-rate and accuracy in a solely routine diagnostic setting using three different approaches as IHC primary testing with complimentary FISH assay, FISH tests as primary testing and double testing using IHC and FISH on a large diagnostic breast cancer cohort.
Using immunohistochemistry as primary testing from 2001 to 2004 resulted in a substantial variation in score 3+ cases and in an unsatisfactory congruence to the complementary FISH testing (53% to 77%).
When using FISH methodology as primary testing between 2005 and 2010, we observed a constant positivity-rate from 16-17%, which slightly dropped to 13-14% after implementing the modified ASCO guidelines in 2008.
trend test based on the number of rare alleles carried as the primary test of association, as the true underlying genetic model is not known.
