Because of the expected $30 cost and the need for a smartphone to receive results, this particular test is unlikely to be the game-changer several public health experts have been calling for — a test that families could use routinely at home before leaving the house, to prevent silent spread.
The Ellume contract is "a step in the right direction towards identifying fast tools that can actually help serve to identify and slow spread," says Dr. Michael Mina, a Harvard epidemiologist who has been a vocal advocate for widespread rapid tests. What's needed, he says, are "tests that are highly accessible, abundant, can be used frequently, provide immediately actionable results and are $5 [or less] per test. A test that does not meet each of these [criteria] will not perform well as a public health test to fight this pandemic."
