Some researchers say there could be a way to help solve the testing riddle, by getting much more out of each individual test through a method known as 'group testing.' But big questions remain:
Kotlikoff, a former 2016 write-in presidential candidate, said he has conveyed the national group testing plan to some members of the White House coronavirus task force, but so far he has not received any word back from the administration.
"This technique could be helpful in areas of low infection prevalence and needs to be validated," the spokesperson said."The Department of Health and Human Services has taken a multifaceted approach on COVID-19 testing to control and ultimately end this outbreak." In the Nebraska study, researchers determined that the five samples mixed together was the right number, and said that using such a method would result in using 57% fewer tests on average to reach the same number of individuals.
Using the system, the researchers claim that around 10,000 people could be tested at a time using around 120 tests, a small fraction of the number of test kits that would have been required if every person was tested individually. Frazier said some of his Cornell colleagues whose academic focuses include population medicine, molecular biology as well as animal medicine were looking into how group testing could be used for universities as well.
But he said that it remains to be seen how much dilution would be a problem especially using such large second order groupings as Frazier and Kotlikoff propose, and there would have to be a"validation process" to combat the false negatives.
