A new way to make tampons could be faster and more effective: take saliva instead of a nasal or throat swab.
Possible alternative
A study from Yale University (not yet published)
he tested the saliva samples and called them “an interesting alternative”: a minimally invasive test, less risky for healthcare professionals (you can collect the sample yourself, like for urine) and also seems very sensitive. In the academic test, saliva produced increased detection sensitivity during infection. In one case, a healthcare professional’s swab was negative for two days before the third was positive, while saliva detected the virus immediately. In a separate investigation, the Yale University team said saliva could detect the virus only in mildly ill people, while a nasopharyngeal swab could not.
Used in New Jersey
the New York Times He writes that the first saliva test is already being offered in some areas of New Jersey. The saliva is immersed in a liquid that holds it until it can be analyzed. This could allow the development of kits that people could have at home and then mail or deliver to a lab. The analyzes in New Jersey were possible because on April 13 Food and Drug Administration The United States has performed a saliva test developed by a Rutgers University laboratory, RUCDR Infinite Biologics, an authorization for compassionate use in an emergency, a procedure that allows you to skip some steps. Rutgers has already processed nearly 90,000 tests and plans to hit 30,000 a day. Results are available within 72 hours. Swabs now have faster results: some quick tests provide results in minutes. The Rutgers test often produced a stronger signal than the swab, fewer false negatives, and no false positives in all samples tested.
