The phrase "ascertaining infection" is correct and usable in written English.
It can be used in contexts related to medical or scientific discussions, particularly when referring to the process of determining whether an infection is present.
Example: "The laboratory is focused on ascertaining infection through various diagnostic tests to ensure accurate treatment."
Alternatives: "determining infection" or "identifying infection".
However, our choice to focus exclusively on a hospitalised population was guided by the desire to have a gold standard, namely, validated medical diagnoses in hospital discharge summaries for the purpose of ascertaining infections.
A network of laboratories ascertains infection with any of the 5 organisms under surveillance within the region.
Nevertheless, its high sensitivity and specificity make the test applicable to ascertain infection status and to serve as a reference for assessing the performance of high-throughput second-generation assays such as enzyme immunoassay.
Other investigations of leukaemia and infections in early life (Dockerty et al, 1999; Chan et al, 2002; Perrillat et al, 2002; Jourdan-Da Silva et al, 2004; Ma et al, 2005; Macarthur et al, 2008) have primarily ascertained infection from parental recall, but this has been reported to be an inaccurate method for collecting data on childhood infections (McKinney et al, 1991).
Other recent studies have ascertained infections primarily from parental recall.
In general, serology is the mainstay for ascertaining viral infection status.
An aliquot of Ad-GFP-infected MSCs was visualised using fluorescent microscopy (450 nm excitation) to ascertain the infection efficiency.
It is able to reveal whether ascertained CMV infection is congenital or postnatal at an age when viral isolation is not able to do so.
It was impossible to ascertain when infection occurred for case-patients with multiple days of exposures.
(The most desirable design, prospectively ascertaining incident infections and subsequently monitoring progression, would likely be prohibitively difficult).
