According to a recent report from the US Daily Science website, American scientists wrote in the latest issue of the British "E Biomedicine" magazine that they conducted a systematic review of relevant papers and literature, analyzed data from 3432 respiratory samples, and analyzed the nasopharynx Three methods of swab, oropharyngeal swab and sputum collection were compared

Early and accurate detection is essential to stop the spread of the new coronavirus and provide patients with appropriate care

In the latest study, a team of Dr.

Li said: "The gold standard inside and outside the hospital is nasopharyngeal swabs, but there are still many confusions as to which sampling method is the best and most sensitive

The researchers explained that nasopharyngeal swabs collect samples through the nasal cavity; oropharyngeal swabs collect samples by inserting a tube in the mouth; and sputum samples are usually collected by allowing patients to cough deeply to produce and expel sputum

Of course, this meta-analysis only includes studies on hospitalized patients, and other studies are needed for asymptomatic or mildly symptomatic patients
