NYC physician develops rapidly, non-major COVID-19 test


According to a preliminary study by a fertility doctor in New York, it can give accurate results in 30 minutes or less.

The reproductive endocrinologist who runs the Columbia University Fertility Center, Drs. The test, developed by Zev Williams, uses a person’s saliva to screen for COVID-19.

A small sample of saliva is placed in a tube containing the enzyme and a compound that causes a chemical reaction first from the tube, then heated with a heat block. The liquid in the tube turns yellow when it turns red when positive or negative for the virus.

“We wanted to design a single step test, with all the work being done by enzymes and chemicals rather than cartridges and components,” Williams said.

According to a preliminary study published by Williams on MedRxiv, one step, the rapid test was able to detect something as one or two copies of the SARs-CoV-2 virus in a microliter of saliva – meaning it could detect Is whether the person is infected even if they have low concentrations of the virus.

“Low threshold detection ensures that you can detect the virus in infected individuals, even if they are asymptomatic,” Williams explained.

The study, which has not been peer reviewed, also reported a sensitivity of 97 percent and specificity of 100 percent.

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 did not produce a positive result, whereas when the sample was positive, it was detected correctly 97 percent of the time.

The Chairman and CEO of Sorrento Therapeutics, Drs. Henry G said, “This test is very simple, very fast and very accurate.”

“Currently there is no accuracy of other tests.”

If the test proves successful in further testing, Williams hopes that this contract may help prevent the spread of contagion by tracing assistance.

Williams said, “When you get results it allows you to separate quickly so that they don’t stretch it and it also allows you to do contact tracing.”

“If you get a result after a week, luckily trying to do contact tracing if they took the metro system after it was lost.”

The current COVID-19 test includes a nasal swab and specialized laboratories and machinery, which slows the test and delays results in days, or even weeks.

The SVP of regulatory affairs in Sorrento, Drs. Alexis Nahama said, “The problem is the delay between the time of getting your test and the result.”

“We need to bring tests to take people’s samples and take them to the lab because that’s where it breaks today.”

Sorrento is conducting a large study of saliva testing before applying for FDA emergency authorization next month.

The cost per test is expected to be less than $ 15, Williams said.
