In the fight against Ebola, medical professionals have long asked for
a test that can quickly and easily identify the deadly virus that has killed nearly 10,000 in western Africa.
The World Health Organization announced Friday
that it has approved a new rapid test for Ebola, which gives results in
15 minutes. The new test, called ReEBOV Antigen Rapid Test, lives up to
its name; it’s much faster than the standard laboratory test, which
requires 12 to 24 hours for results, according to Reuters.
And the new test is streamlined to use much less equipment: it’s simply
a piece of paper and a test tube. With no electricity required to
operate and its small size, the test can be carried and used in remote
areas.
“It’s
very similar to a pregnancy test,” Doug Simpson, who designed and
produced the test at the Corginex Medical Corporation, told NPR. “A drop of blood is placed on the paper, and if two lines appear, then it's positive for Ebola.”
In the blood, the test is searching for the Ebola protein, rather
looking for the genetic material of the virus, the nucleic acid, which
is used in standard laboratory tests. As a result, the margin of error
with the ReEBOV Antigen Rapid Test is slightly higher, but the Guardian reports
that trials show it can correctly identify about 92 percent of
Ebola-infected patients and clear 85 percent of those not infected with
the virus.
Even though it’s not perfect, the rapid test will help doctors
quickly identify the beginnings of an outbreak and quarantine the
infected individuals. This also helps solve the problem of healthy
people being quarantined while waiting for their results and getting
infected during the waiting period.
NPR reports
that the first shipments of the ReEBOV Antigen Rapid Test will go out
to West Africa in about two weeks, because the U.S. Food and Drug
Administration is required to give a final approval before the product
can leave the U.S.
While the price tag for the rapid test is currently unknown, Simpson told NPR that it will cost far less than the current standard test for Ebola.
Due to the margin of error in the ReEBOV Antigen Rapid TEST, medical
personnel will still need to conduct a backup standard test if someone
tests negative, but according to U.S. News, Dr. Bruce Aylward, WHO’s assistant director-general, said “(the new test) might help us get to zero faster."
