“#NYC doctor develops rapid, noninvasive COVID-19 test<\/strong>”<\/p>\n

\n A New York fertility doctor has developed a rapid, noninvasive coronavirus test that can deliver accurate results in 30 minutes or less, according to a preliminary study.<\/p>\n

The test, developed by Dr. Zev Williams, a reproductive endocrinologist who runs the Columbia University Fertility Center, uses a person\u2019s saliva to screen for COVID-19.<\/p>\n

A small sample of saliva is placed into a tube containing enzymes and a compound that causes a chemical reaction before the tube is then warmed up with a heat block. The liquid in the tube turns yellow when it\u2019s positive for the virus or red when it\u2019s negative.<\/p>\n

\u201cWe wanted to design a single step test where all the work was being done by enzymes and chemicals rather than cartridges and components,\u201d Williams said, adding that enzymes and chemicals are easy to scale and distribute.<\/p>\n

The one-step, rapid test was able to detect as few as one or two copies of the SARs-CoV-2 virus in a microliter of saliva, according to a preliminary study published by Williams on MedRxiv \u2014 meaning that it can detect if a person is infected even if they only have a low concentration of the virus.<\/p>\n

\u201cLow limits of detection help ensure that you can detect the virus in infected individuals, even if they are asymptomatic,\u201d Williams explained.<\/p>\n

The study, which has not been peer-reviewed, also recorded sensitivity of 97 percent and specificity of 100 percent.<\/p>\n

Sensitivity refers to the ability of a test to correctly identify infected patients, while specificity is the ability of a test to correctly identify those who are not ill. In this case, when the sample was negative, the saliva test didn\u2019t deliver a false positive result, while when the sample was positive, 97 percent of the time it was correctly detected.<\/p>\n

\u201cThis test is very, very simple, very fast and is extremely accurate,\u201d said Dr. Henry Ji, chairman and CEO of Sorrento Therapeutics, which has partnered with Columbia University and is licensing the test.<\/p>\n

\u201cCurrently the accuracy of other tests is not there.\u201d<\/p>\n

If the test proves successful in further testing, Williams hopes it can help curb the spread of the contagion by aiding contract tracing.<\/p>\n

\u201cWhen you get the results back quickly it allows you to have the individual be self quarantined so that they\u2019re not spreading it and it also allows you to do contact tracing,\u201d Williams said.<\/p>\n

\u201cIf you get the results a week later, good luck trying to do contact tracing if they took the subway system once you\u2019ve lost.\u201d<\/p>\n

Current COVID-19 testing involves a nasal swab and specialized laboratories and machinery, which slows testing down and has resulted in delays of days, or even weeks, in delivering results.<\/p>\n

\u201cThe problem is the delay between the time you test and the time you get the results,\u201d said Dr. Alexis Nahama, SVP of regulatory affairs at Sorrento.<\/p>\n

\u201cWe need to bring the testing to the people versus taking the people\u2019s samples and taking them to the lab because that\u2019s where it breaks apart today.\u201d<\/p>\n

Sorrento is conducting a larger study of the saliva test before app<\/a>lying for FDA emergency authorization next month.<\/p>\n

The cost per test is expected to be under $15, Williams said.\n <\/p><\/div>\n
