The United States approved the new coronavirus “saliva test method”. Foreign media reported that it will reduce the risk of infection of medical staff.
Foreign media said that researchers from Rutgers University in the United States obtained the first batch of saliva tests from the US government to help confirm the diagnosis of new coronary pneumonia (COVID-19). This method can help expand detection options and reduce the risk of infection by medical personnel.
According to the Associated Press reported on April 13 in Washington, the New Jersey State University said on the 13th that the US Food and Drug Administration authorized this test method based on emergency disposal authority to combat the epidemic. The first batch of tests will be conducted through hospitals and clinics affiliated with the school. Today, communities across the United States are still doing their best to carry out testing to help track and contain the new coronary pneumonia epidemic.
The currently used COVID-19 screening method requires medical staff to use swabs to extract laboratory specimens from the patient’s nose or throat. In order to reduce the risk of infection, many hospitals and clinics require staff to discard gloves and masks after close contact with people who may carry the new coronavirus. But now many medical institutions are struggling with the shortage of basic medical supplies such as gloves, masks and swabs.
According to reports, with the new saliva detection method, patients can spit saliva into plastic test tubes multiple times, and then give the test tubes to medical staff for laboratory testing.
Andrew Brooks, director of the Rutgers University Laboratory that developed the saliva test, said: “This prevents medical staff from directly contacting people with symptoms.”
According to the report, an infectious disease expert who did not participate in the development of saliva detection method said that this method also helps to alleviate the difficulty of extracting laboratory specimens with swabs and the discomfort caused to patients.
Dr. Amesh Adarja of Johns Hopkins University said: “Now I hope that various options can be used to deal with various situations, so that as many tests as possible can be carried out in an appropriate way.” A Darja emphasized that similar saliva testing in the past has helped expand the testing of AIDS and other diseases.
The report said that Rutgers University used saliva test and swab test on 60 patients to test the accuracy of the former. The result is that the saliva test is completely consistent with the swab test.
The report also stated that Rutgers University developed this laboratory test method using the saliva collection box produced by Spectral Solutions. The Utah-based company has been providing similar equipment for blood line detection based on DNA. According to Brooks, the Rutgers University laboratory currently processes 10,000 patient test specimens per day.
In its authorization letter to Rutgers University, the US Food and Drug Administration stated that testing should be carried out “in a medical and health setting and under the supervision of trained medical personnel.” The Food and Drug Administration has not approved any household COVID-19 testing method, but several companies have announced plans to provide such services.
The Food and Drug Administration also stated that patients with negative saliva test results should take another test to confirm the test results.
