New rapid Anthrax test developed through collaboration between
Mayo Clinic and Roche Diagnostics
Test, which provides results in less than one hour, will be made
available to United States laboratories
ROCHESTER, MN (November 5, 2001) - Mayo Clinic has developed a
new DNA test to rapidly identify anthrax in human and environmental
samples. Roche Diagnostics is making the test widely available to
public health agencies, hospital laboratories and reference laboratories
in the United States and other countries. The new test can identify
the presence of anthrax in less than one hour instead of days.
"The first thing people want to know in a case of suspected
exposure is whether the agent was in fact anthrax," says Franklin
R. Cockerill III, M.D., the Mayo Clinic microbiologist who led the
development team. "Until now, local labs have been able to
quickly determine the presence of a bacterium, but they cant
tell whether it is anthrax or not. The current process to identify
the presence of anthrax may take several days. The events of the
last several weeks require as rapid a response as possible."
Roche plans to give regional and local laboratories the ability
to perform rapid DNA testing, eliminating the waiting period currently
required at most laboratories to identify anthrax. Thus, a larger
number of laboratories will now be able to provide a rapid yes
or no answer.
"This rapid identification will enable doctors to begin more
timely treatment of patients who have been exposed to anthrax, and
it will more quickly alleviate undue anxiety for people who havent
been exposed," says Dr. Cockerill.
The Mayo Clinic team led by Dr. Cockerill developed the test using
Roche's LightCycler® instrument for polymerase chain reaction
(PCR)-based assays. To make the test widely available, Roche significantly
accelerated production of the reagents needed to run the assay.
"Making this test available in a very short time-frame is
our contribution to the fight against bioterrorism and is a direct
outcome of the excellent cooperation between Roche and Mayo Clinic,
says Martin Madaus, President and CEO of Roche Diagnostics Corporation.
Mayo researchers have several years of experience in developing
assays . The speed and broad distribution of the LightCycler®
made it an ideal platform for developing the anthrax test. By combining
our efforts, we are able to make this test available to qualified
laboratories only a few weeks after beginning this initiative.
The test materials will be made available to about two dozen geographically
dispersed LightCycler®-equipped laboratories. The timing of
the local availability will vary location to location, but some
may be available as early as later this week. Mayo Clinic has been
working with the federal government to make the test formula available
to any federal agency that requests it, and is lending its expertise
to state and federal health officials in the wake of the reported
cases of anthrax exposure. Roche is working with the FDA to determine
requirements for expedited regulatory approval. Tests will be offered
initially to laboratories at no charge.
"People who suspect they have been exposed to anthrax should
contact local law enforcement officials, who will assess the situation
and take appropriate steps," says Dr. Cockerill. "These
officials will investigate possible exposures and, with local laboratories,
will determine whether this rapid testing is warranted. Those who
are experiencing unusual, flu-like symptoms should contact their
physician."
Mayo Clinic recommends that it is best to have specimens tested
at the nearest regional location to realize the full advantage of
the rapid return of results that the new test offers.
"The time involved in transporting samples to Mayo Clinic
also would undermine the main goal of the test, which is rapid identification,"
says Dr. Cockerill. "That's why we have helped Roche make the
test available locally, to speed the preliminary diagnosis and improve
patient care. We are pleased that after a few weeks of round-the-clock
efforts, that goal has been achieved."
